A really good interesting video Dave, fantastic editing, I appreciate the sounds effects and photography! Those Oaks are going to grow really well in the new pots and soil.
Thanks Nigel, I really appreciate your kind words. Yes when they grow bigger the pyrenean oaks are very pretty, especially with their tightly spaced small leaves.
Thanks ! I'm flattered that you would be interested... but this year the video would be like 30 seconds long! Basically they're all still in these grow pots for this year, thickening up. Next spring I'll do a Year 4 update, if all goes to plan. The seedlings in bigger white pots will stay in their pots until year 5 but all the oaks in smaller black pots, I'll repot them into the white pots. It's also a chance to inspect how the roots are getting on, and hopefully remove the rest of the tap roots.
@@BlueSkyBonsai awesome! I'm interested in learning how to develop a future bonsai from seed/seedling and I think this series has a lot to offer on that department! I germinated one european oak (quercus roble) and one cork oak (quercus suber) which grew absolutely huge just these season (~60cm)! I will rewatch this video to cut the tap root next spring! Greetings from Porto!
Great idea to use the tourniquet on seedlings. I’ve used that process to fuse clumps and to eliminate reverse taper. I Never used it with seedlings but I will now. No wonder many of my seedlings don’t make it. Thanks
Cheers Matt! Yep, I noticed a few years ago that some of my seedlings withered beyond revival after I chopped the tap root, and others just didn't bud out until mid summer when there's less of the growing season left to grow. So tourniquetting and taprooting over two years seems to avoid that risk. I wonder why oaks seem to tap much thicker than other trees. It's also, I guess, the reason why I have never successfully kept oak yamadori alive.
Hello blue sky bonsai! Nigel Saunders tipped me off to come check out your channel I think I might be interested in some oaks now. keep making the great videos
I’m so excited for you and your new Oaks, Growing from seeds like a pro! You shared advice with me several months back on the Oaks seedlings I found in my yard most likely from squirrels. I dug them up, clipped the tap root, which was about 16” long! They survived the freeze if the century we had this winter and budded out! For the third one that was much bigger, I dug down about a foot on one side and cut the tap root and placed a glazed square tile under the cut portion and covered it back up. I’ll let it be for the summer and dig it up next year . You mentioned it might be harder to transplant since it was much bigger and I thought this might be an interesting way to deal with the tap root. It seems to be doing well, new leaves look happy! That you for your advice and feedback! I most likely would have let them grow far too long in the ground had you not suggested digging them up. I also like the idea for using the wire to slowly choke off the long tap root. As always, I appreciate your videos and the care in which you take to provide such helpful information! Cheers to another growing season and the fun it brings!
Thanks so much! I remember it well; I'm so happy yours have budded out and are doing well. They will make fantastic bonsai in the future. It's a great plan to plant a glazed tile under the roots - that will make it so much easier to pot up in the future. Cheers! 🌳👍
Cheers Edinborogh! Yes the tap root can be horrendous in some seedlings. But it does help to think there's always another year! you can deal with it over 2 or even three goes if necessary. Glad the video helped - thanks!
You’ve again given us a great summary on a specific tree. I’ll be using it to rehab our Burr Oak. Your oak seedlings look to be very interesting, and should become a prized bonsai.
Thanks Jeff! yes I think the oaks all make wonderful bonsai, I have five different species developing -- two you saw in this video, and also Holm oak (aka holly oak), Cork oak, and Portuguese oak. I haven't seen any Burr oaks here in Europe, but looking at pictures of them, they look fantastic full size. If you can reduce the leaves they would make super bonsai. I also like the look of pin-oak leaves but I think they are just too big; not sure they could be reduced sufficiently for a convincing looking bonsai.
Thanks OB! Yes if ever you are considering what to use as potting soil for seedlings or any plants... that 16-month like-for-like comparison is clear enough for me. Cheers!
@@OddBonsai yep! Also there's a lot to be said for trying it out yourself and seeing the results first hand! I was surprised at how well the vermiculite worked on its own, but, it was much stickier and trickier to get off the roots than akadama or cat litter.
Good stuff man. I have nine acorns that have been rooting for the last month and have started to sprout above ground. This is my first ever attempt at bonsai (let alone oak bonsai), so your directions are invaluable for my confidence going forward.
What a wonderful video. I have two English oaks grown from acorn, about 4 years old now, and they're doing well, although I think I need to reconsider the soil as I feel the trunks should be thicker by now. The diameter of the larger of the two is about 15mm at its base.
@@jgp9260 thank you! I have seen that the English oaks like to shoot up fast and high before the trunk starts to thicken significantly. They grow faster in the ground, which I think is because oaks push down a massive thick taproot, which they can't do in a pot. Of course the disadvantage is then it's much harder to uproot then tame the root system. So I griw mine in deep pots. What soil are you using? And are you fertilising sufficiently? Also, how deep are the pots?
this is exactly what i was looking for! i killed two oak trees this year from chopping the tap root and not leaving enough fine roots. i won't be making that mistake again next year. got several oaks that are just germinating ready for spring. also, love the bench. watched the video where you built it and i think i'll have a go ready for this summer
Sorry to hear about this year's oaks. I have also lost several oaks in the past, tried to take some as yamadori and they all died. They are pretty sensitive if they don't have enough fine roots. When you start on your benches next year drop me a line and I can give you an update on mine, what I'd do different next time, etc.
Cheers Ian! Yep - and amazingly a few of the seedlings I decided to tourniquet have already wilted substantially in the hot sun, so I'm really happy I didn't just do the chop and hope because I'm sure they wouldn't have survived. Hey maybe they still won't make it through summer! 😂
I left the acorns on mine, and one fell off the other week by itself. :) Thank you for the great video. It reassured me that I did the right thing when I cut the taproot where I did. XD
I'm so glad you found you had done the right thing. TBH this video was one month too late or even 6 weeks late. But that's a glimpse into my life and how I have zero time spare... hey, first world problems etc... I shouldn't complain! Thanks S.Y.
@@BlueSkyBonsai Totally! Thank you again. Now I know how to prune the tap root of my 2 year-old trees that I collected as tiny saplings last year. I subscribed to your channel and I hope to find the time to explore your videos some more. Also love your channel name. I want to create a photo garden blog with photos of our garden but couldn't yet think of a fitting name, haha. Kind greetings
@@Dispatern it's getting quite late in spring by now to prune the tap roots. If it has already grown several large leaves then you might be risking killing it to prune off the tap roots this late in the season. You could still do the torniquet part only now, then do a more severe root pruning next spring in early march?? Ps. Good luck with your blog name!
@@BlueSkyBonsai Thank you for the advise. I'll prune the tap root next spring then. Is it okay to prune the tap root of 3 year-old trees or would the ideal time have been in the second year? That's something I'm confused about. (I've got a green thumb but I'm fairly new to the wonderful world of Bonsai.) Thank you! Every project starts with a name :) Have a nice weekend and thanks a lot for your tips. I appreciate it.
@@Dispatern it's okay to prune the tap root year 3 as long as there are plenty of fine roots still attached to the trunk (ie above where you prune). And as mentioned do it just as the leaf buds are swelling but before the leaves have all started to extend.
Hi Isa, that's great to hear! I'm also happy for you. Are you going to be brave and tourniquet your tap root? Or will you wait until we can visit next??
Thanks for the video! I collected some monterey cypress cones a couple months ago and some of those seeds actually germinated! Unfortunately two of them died but I'm hoping some of the other seeds start to germinate as well. I haven't started any bonsai from seeds yet so it'll be an exciting endeavor if I can get it started.
Thanks Garrett! That's why I always recommend planting many seeds, because some wil always die along the way. Growing them from seeds is really special, because you did everything to the tree from before it even became a tree. Good luck with the remaining cypresses!
ty for teaching me so much so shortly, with all your vids! my trees will thank you too, ive been torturing them with wrong trim times and wrong root pruning times. how have my trees suffered. idk how they survived....dam i just need to keep them healthy in a pot b4 i think about actually learning how to prune and the right time....slowing learning the art, trying to rush bonsai is a lost cause...
You're welcome, and, you're right to see that you can't rush bonsai. Part of the beauty of it is in the long term development and seeing your work from 5 years ago come to fruition now! Some trees survive much easier than others. Elms and ficus for example seem to survive all kinds of chopping and hacking! But at the same time, it's inevitable that we will lose one or two trees along the way. What trees do you have?
Booom!!! Great video. I have had the tap root issue with trident maples, and London plane trees. This turniquet idea is amazing. I never would have thought of that. The tap root makes repotting terribly difficult with seedlings. Im going to use this technique in the future. Thanks broski. 😎🍺🍺
Cheers Broski!! Glad you liked it.. the tap roots have to be dealt with of course, but, if that threatens the survival of the seedling then it defeats all the work you've put in so far. Actually a few of the seedlings that I tourniquetted have already wilted a bit in the hot sun, so I'm double glad I decided not to completely chop the taps. Ps. Madrid out against Chelsea last week, did you see the match? Madrid's defense was worse than nomal, so it was almost predictable result, but my son was really sore!
Yes, at 3:08 you see this was grown in 100% vermiculite and it grew really vigorously. For acorns you don't need to fertilize in the first year, but from the second year I recommend fertilize every two weeks from Spring through to autum.
You never let us down with the quality of your video and information. I love dealing with oaks and that tap root is the problem we all must face...at some point. in my growing beds I undercut once a year to ensure the tap doesnt go to Japan! I had never heard of the tourniquet method and I wish I had. I presume ti would work as well with some of our other species - hawthorne, Larch and Hornbeam? Thank you.
Thanks Xavier! One of the things I love about oaks is their lovely leaf shape, but at the same time those leaves draw up tons of water from the roots. This is why I find it safer to tourniquet the tap and deal with it over 2-3 years rather than a "Hail-Mary" "chop and hope". I have lost 2 oaks (that I can remember...) due to severe root pruning too late in spring when the big leaves are already demanding lots of water. I have also tourniquetted Japanese maples, sycamores, mulberry, anything with bigger leaves that risk dying of thirst after a tap-root chop. Elms and hornbeams can take quite a heavy root chop and survive ok - I haven't bothered tourniqueting them. Never tried it on a hawthorn (I don't have any) but Larch - I have one thickening up in a deep grow pot so I will inspect the root system next spring and decide whether to tourniquet it. There is a potential downside to the tourniquet. It can give lopsided or uneven radial roots. My biggest Japanese maple in a grow pot still has its tourniquet but I can't really use the resultant roots: one is so much bigger and thicker than all the others. And there is a big gap. So I will have to tourniquet again above the roots or do a full ground layer next spring. But for oaks, it's still better to do this than continue growing the massive tap root and sending out feeder roots 30cm under the trunk base...
Very interesting, I'd love to see the root development after the tourniquet! I'm starting with some pines, I'll be lucky if I get that much growth after a couple more years.
@@Augustinion yes, I did it in spring this year, but unfortunately time ran out and I didn't make a video of it. Luckily I took some photos, if you're interested you can see them in this album: www.flickr.com/gp/davidhseymour/2t571HB25q -you need to scroll down a bit. I repotted them into the same deep grow pots, to keep thickening them up for another couple of years. If I get more time next spring I'll do a video. Maybe take a few out again and inspect, with a kind of "what worked and what went wrong" angle, maybe lessons learnt.
I get so excited when you post a new video, and this was great because I just planted 20 Cork oak acorns and have some English oak stratifying now. Can you keep.track of what you do with these pre bonsai over the years so you can make that pre bonsai development video we talked about last video? How, when and why will you wire these saplings? What's your plan for them? What style? OMG.... I wish I could share a fee Bottle's of wine chatting about bonsai with you mate. Thanks for another cracking video!!
Thanks Raphael! Glad this video met your expectations.. and was relevant to your oaks. You've picked two great oak choices to develop. Of course the English oak is deciduous, but the cork oak is evergreen - they have wonderful small leaves a bit like holm oak but a deeper green and less spiky. I have two corkers, one is two years old (i.e. in its third year) and the other only 1 year old. They were both out all winter, so we know they can withstand snow and sub-zero temperatures for a significant period of time. Just saying, because they are most common in southern spain and portugal where they don't get much freezing temperatures. Haha the wine sounds good, I also drink beer by the gallon! I plan to leave my english oaks for several years to get bigger and fatter, but some of the pyrenean oaks I will probably start to bonsify sooner because they are slower growers and have smaller leaves. It's also the advantage of planting many acorns, like you did-- you have a lot more options each year for deciding whether to bonsify or continue trunk development. I'm not too keen on wiring seedlings. On one hand, now is a great time to do it, but on the other hand if you leave that wire on for just a few weeks too long, and you'll have the tell-tale spiral wire mark for many more years .. the growing bark takes a long time to forgive and forget! Maybe I will wire just a couple of them for interest but the best bet then is to unwire and rewire each 4-6 weeks, to avoid the scars. Too much effort for me, especially when you're also watching dozens of other trees. Anyway, yes, I'll continue to track these along with some of my other developing trees. And now re-reading my reply here, maybe the subject title of my future pre-bonsai development video could be "to bonsify or not to bonsify", I believe I might have invented a verb here unless someone has already coined it. 👍🍻
Hi Dave, this David from Australia,, last year I planted 6 tulipwood and cassia fistula ( golden shower) in peat moss, all sprouted but looks a little weak. This spring I'll use your advice and plant more seeds in a more efficient mix
Great stuff David, the key is drainage so that every time you water them, a pot-load of air is also sucked down into all the pores in the soil which is essential for root health
Hahaha yes, lived in Madrid for over 20 years, I drop it into a few of my videos but this time I said it right near the beginning so you couldn't miss it! In a week or two I will be attempting to construct some kind of semi-shade over the bonsai benches. Some trees love the strong sunlight, like the oaks and elms, and of course olives love full-on direct sunlight. But my Japanese maples seem to get leaf burn every year and it's not for lack of watering! Azaleas suffer too. Cheers Edu!
@@BlueSkyBonsai yeah, i just got a couple of maples and was just thinking about doing the same, but for now I'll just keep them in a shaded area. Take care!
@@PSPMHaestros thanks! Hey it's a tricky situation though, of course they need sunlight to grow, and in the shade they sometimes develop bigger leaves. But bigger leaves are better than burnt leaves, given the choice.
Thanks! I don't have any bald cypresses, they're very rare in Spain. So I can't say from personal experience. If you do try the tourniquet method, there are a few things I've learnt since this video. 1, use a thick enough wire to ensure the bark doesn't callus over the wire, and wrap it 2 or 3 times around the trunk. 2, remove ALL roots above the tourniquet, otherwise they will grow much bigger and thicker than any new roots. 3, Bury the tourniquet deeply enough in the soil so that the new root plane you want doesn't become uncovered. Hope that helps!
Great video, any chance we can get the follow up, like the trees health and how to help them along, I just replanted a few cuttings and another small yardadori and they seem to lose some leaves when I transplanted them from potting soil into an akadama mix.
Thanks Robby! Not sure if you already saw this video about ensuring your cuttings take root: th-cam.com/video/RnGfUeQC7r8/w-d-xo.html For a few weeks you need to have the cutting in an incubator or propagator to keep the humid at 100% to keep the leaves alive. Also, keep the pot resting in a shallow bowl of water for a few weeks so that the akadama stays wet. You can do this with a cutting to encourage roots, but not a seedling that already has roots because you have a risk of the water stagnating and then possibility of root rot in that water. Hope that helps!
No, sorry Darren for some reason I only took video, no photos. The thumnail is from a screen capture during the video. Or did you mean, how the roots have grown above the tourniquet 1 or 2 years later?
@@grobonsai same, I have some oaks and JMs with tourniquets but they're stil buried. Have you read Harry H's 'Inspirations' books? He has some good pictures of his touniquet results in ... can't remember if it was book 1 or book 2. I'll have a look now.
Thanks Chris! I did this last spring to over 40 seedlings, and only 1 died. I did it slightly too late in spring - the leaves had already opened up on most of the seedlings. The best time is just before the leaves unfurl, when the leaf buds are really swelling and ready to pop.
Very good explanation Dave. I know this method can be used to air layer certain species but wondered if you can use this to grow an entirely new root base further up the trunk on a more mature tree?
Thanks Toby! I have never tried a touniquet on the main trunk. I'm not sure it would work. One of the risks of air layering is that the bark starts to callus horrendously and that's why it's important to cut the layer right through the cambium and leave a sufficient space bare so that the callusing can't hinder root growth. So I think to use a tourniquet alone, the trunk would callous over it. I think you'd need to combine it with the cut layer. I might be wrong though...
I always try to cut the tap root in the first year, ideally after it started growing. That way much more of the acorns energy can go into the fine roots. It will try to create another tap root though sometimes.
@@BlueSkyBonsai you don't need any if you do it early enough because the acorn supplies the tap root with energy and will push out fine roots just faster and more vigorous if you cut it at this early stage.
Hi, I chopped the tap root last year, unsure how well I did as I've never done it before. In your video you say to wait about 2 years but should I check again this year to see if I need to do any more cutting?
@@sarahrhi82 even if you don't prune the roots now, Spring is a good time to lift it out of the pot and inspect the roots. So you can see if it has rooted prolifically and there are loads of fine roots coming from above the tap root, that's your chance to cut the tap root further now. But if you're not sure, leave it another year. Patience is the key in bonsai!
Good call! Yes I do want to do an update on this - let's see if I get the time over the coming months now my book is finally finished and published! In summary, many of these tourniquet jobs turned out great, but a few of them failed. You can see some results in the last 10 or 11 photos in this album: flic.kr/s/aHsmJ7vVRq The few failures were caused by three different issues: 1. one wire was too thin so the tap root callused over it and continued to grow. 2. Another tourniquet was not buried deep enough so the wire became slightly uncovered, and again the tap root continued to grow. 3. The ones where I left a root growing above the tourniquet, they didn't fail but got a new problem - the root that I left grew much bigger than any of the new roots, disproportionately big, so I had to remove that. You'll be happy to hear that these failures and how to avoid them, are documented in my book!
I have a very small oak 6-7 inches , with two leaves. I dug it up and potted it so I could 'look after it' but having seen your video I think I've probably stalled it as I put it in a pot with something like miracle grow compost. It's ok but seems to be very much in slow motion a year on. It looks like I should change it's soil for??...vermiculite?? Please can you recommend what to do as it's now getting sunny here in west wales and its starting to leaf but incredibly slowly. I'm 53 and I'd like to see a bonsai of it in my lifetime if I'm lucky 😂. Many thanks 😎
I wouldn't recommend vermiculite because it gradually breaks down in the winter freezes - I did it on this on tree as an experiment. Much better soil would be: Akadama if you can get, mixed with tiny chopped pine bark and pumice, all seived to get rid of the dust. The reason for using granular soil (instead of compost) is to allow good drainage and to continually get oxygen down to all the roots every time you water. Get rid of the dust before potting so that it doesn't clog up the pores in the soil and the drainage holes. HTH
Hi, and thanks! Yes same applies to q.ilex too. I have four holm/holly oaks from acorns that I collected near my house and planted in autumn 2017. I used the tourniquet trick on them when I moved them to bigger grow pots 3 years ago. If you're interested they are in my holm oak album in Flickr here: www.flickr.com/gp/davidhseymour/i8173e The last photo in that album was Nov 2020 so I probably better take some new photos... they are already quite a lot bigger now. I am considering turning one of them into a small bonsai already. I'll need to transfer to an intermediate pot first to train the roots and start developing nebari.
That seedling on 6:38 you could also place the tree higher up and remove those few fine roots, you would have a bigger trunk to start with. At least that would be my choice.
Yes that's a good option. The issue here is that I left it too late in the season to do serious root work and I needed leave a lot of the fine roots on. As it is, some of the trees have lost their leaves as a result of the root pruning and hot dry Madrid air. They'll survive, but I should have done this job back in early march...
Thanks Andrei! Now you say that, I regret not doing a close up of the different leaves. On the good side, I took some pics last year and started an archive on Flickr here: www.flickr.com/gp/davidhseymour/446xb8 I don't have any downy oaks though, but I hope this comparison helps to some extent.
Thanks, i loved the tutorial. I have 2 oak trees, I'm not sure how old they are, look about 1 year. Shall. I transfer them to 100% vermiculite? and if roots look good do what you recommend in video?
Thank you! It depends where you are. If you're in the northern hemisphere, you should wait until early spring next year. Oaks don't respond well to root work in the heat of summer. If you're in the southern hemisphere then you're nearly at the right time to do it, as soon as you see the buds swelling, go for it! Vermiculite worked well but it starts to break down after a year or so, so if you can mix it with perlite or pumice then it should hold its structure for a couple of years. If you can get hold of some akadama then that would work great.
what do you use for soil? Not sure if its just because of trying to ship things with covid everywhere but its very hard to get akadama here. I am trying to figure out what to use for my trees. Thanks for the video!
Try perlite and turface 50/50, seived to rdmove the dust and fines. I prefer pumice to perlite but it's rare to get pumice in 4-5mm particles. Perlite is a very good alternative, but is very lightweight and I prefer heavier soil because it's very windy where I live.
Has anyone ever told you that you say “tourniquet” exactly like Roger Waters in “One of my Turns?” I have to admit that I like those gnarly little twists that sometimes happen between tap root and trunk after a seed germinates. Are you just thinking that they wouldn’t work with oaks since they should be grown in an upright/ informal upright style? Cheers man, killer vid.
Thanks C., funny you should say that... most Brits pronounce it in false-french like "torniquey" but I decided to go for the mid-atlantic pronounciation with a hard T on the end. That, and Roger Waters is my dad.. no he's not, of course. Roger Waters would be great nominative determinism for a garden assistant ("Do you know Roger Waters? No, but thanks for the tip!") Regarding the curly tap root, I kept a couple of them like that, and exposed the twists above the soil like for a bit of fun. I think a tap root with a modest curve would be fine to use as a trunk, but most of the twists were too severe in stark contrast with the straight trunk. Btw, still planning on sending you a couple of them, I'll let you know when they're in the post.
@@BlueSkyBonsai OK so I went back and listened to the song (it had been a while) and sure enough, he says "torniQUEY", all Frenchy-like. Unreal, as I'd always sung it (and heard) a hard "T" when spinning the cassette that I ripped from my CD so I could play it in my '84 hatchback Accord. Also I've googled "nominative determinism" and now understand your Waters joke. Very clever, David. Yes I'm sure the degree of twisty insanity would determine whether that part of the trunk were usable or not...good call. It was fresh in my mind as the same thing just happened to me when repotting a hornbeam (hopefully you'l see that soon). Send what you will, though I am undeserving.
@@BostonBonsaiIdiot For interest: About 40 years ago my dad went into a serious depression after he listened and investigated the lyrics of The Wall. Since then I've never really wanted to get into it! except of course the songs are still on the radio all the time... But if I listen now to Dark Side of the Moon I get massive nostalgia from my childhood.. same with Beatles and one or two others. Now I'm showing my age ...
@@BlueSkyBonsai There's something about the tone of that record that's mysteriously jarring. Add to that the subject matter, and the fact that your dad is British and of a certain age...perfect storm. I totally get it. Luckily, you brits have all the other greatest-rock-bands-of-all-time to fall back on, so there should have been no shortage of musical enjoyment in that house!
@@BostonBonsaiIdiot all true, but I also have to say one of my all time favourites was Simon and Garfunkel, that beautiful music was often wafting round the house in those years and I still love it now. And you had Elvis, and Roy Orbison. So it's six of one, half a dozen of the other...?
Hi Dave, i can't wait until spring to cut my tap roots. I was just wondering, you suggested potting in 100% vermiculite, do you need to feed it? Could I also use lechuza pon?
Hi Sarah, if you use vermiculite or any inorganic granular soil, yes then it's a good idea to fertilise at least every second week. However not straight after repotting/root pruning... let it recover for 5-6 weeks before fertilising. Lechuza pon, never tried it - it looks ok but maybe you need more water retention in your soil - it depends on your climate. Here in hot Madrid that would be too dry too quickly. If your climate is cooler and wetter I guess that substrate might work. But again, not great to use fertilizer straight after root pruning trees in containers ... I see lechuza pon already has fertilizer ingredients. Maybe you could try it for one seedling, and vermiculite for another, then compare the results after a year?
@@BlueSkyBonsai thanks so much for reply. Yes I may do that or mix a bit of the lechuza pon with vermiculite. Is there any particular fertiliser you would use if just vermiculite? Many thanks Sarah
Love the video but help. Been growing bonsai for a while now. But, I don't fully understand pruning. Example, I cut a branch back and it just puts a shoot out. Now I've tried directional pruning straight cut even completely wrong cut. Just end up with a branch that goes on and on year after year. All the growth is always at the end. So I just end up with a long branch and no bi directional or finer or secondary branches. Please can you explain. I can send pics if you need. Thank you Tom.
Hi Tom, I hope I have answered your questions about branch pruning in this video: th-cam.com/video/cOGAJ5iqWfk/w-d-xo.html (part 1) And then part 2: th-cam.com/video/rziuv_Cdf-U/w-d-xo.html If you watch these and still have doubts, let me know! Also, a lot depends on the tree species. Some grow apically (taller/upwards) while others are more laterally dominant (more bush-like). Apically dominant trees can be harder to encourage fine ramification because their genes have evolved for elongation, to push up higher than the surrounding trees. But ultimately all can be encouraged to bifurcate, just some slower than others. If you're finding only one new shoot emerges at every pruning point, prune that back to two or three leaves, then those too when they grow. Keep doing it and consider ramification a long term goal, not something you achieve in a matter of months. I really hope that helps. Above all, be patient and don't give up! 🌳👍🏻
If you cut the tap root in half, will a new extension of tap root, from the original half tap root, continue to regrow. OR does cutting the tap root in half stop the tap root from continuing to grow.
If you cut the tap root in half it can continue to grow new roots from the end and from many points further up the root. In the ideal situation we would want to completely remove the tap root to force all new roots to emerge next to the trunk base. But in the real world that can sometimes mean killing the seedling if it doesn't have enough remaining roots to support the water requirements of the leaves. So that's why sometimes need to cut it in half and use a touniquet to limit further root growth.
I have some English oak saplings which are 8 months old. They are already 6-12 inches tall. Would you suggest leaving it another year before the tap root chop? Its probably too late to do this year.
Yes I would leave them until next spring - early spring just as you see the new leaf buds swelling. Because oaks can be a bit sensitive to root work this close to summer with their large leaf area.
Yes! Also, if your tree already has several leaves like in this video, keep it watered and in the shade for a couple of weeks to prevent the leaves from drying due to a temporarily depleted root system. If it already has a lot of large leaves, put a clear plastic bag over it for a week or so, to virtually stop the transpiration in the leaves while it regrows new tiny roots. HTH!
I'm curious about the success with 100% vermiculite. Do you think this would produce similar results with all or most other oaks? Also, in my admittedly limited experience with live oaks, they don't usually like as much root disturbance as all lot of other trees. Is this different with tree that were germinated in containers (compared to those germinated in the ground)? Would you mind if I contact you directly to discuss as it relates to some oaks I'm currently working on?
Hi Joshua, vermiculite encourages more fine roots but it breaks down after a year, can't cope with more than two winters outdoors. So yes I would use vermiculite again for other oaks' acorns too, knowing that in the second spring I have to repot, like in this video. Most oaks don't like too severe root work, but it's much less risky at the start of Spring just when you see the buds swelling ready to pop. Yes you can email me if you want, dave@blueskybonsai.com
Question Dave. I’ve got 6 English oak acorns (kindly sent to me in Connecticut from @Tonys Bonsai) planted in one pot. When would you suggest separating them into individual pots? Thanks
Hi Matt, if you have the extra pots and space, I would separate them (carefully) as soon as you see the roots starting to extend more than an inch or so. The longer you leave it, the more work it is to untangle them. Even if you're planning to develop them as an oak forest, it's still easier to grow them separately for the first few years so each one gets the water and nutrients it individually needs, and so you can prune each tree's roots separately before combining them in a group planting. Whereas, if you keep them together then you're (almost) stuck with that positioning configuration of trees. And pruning tap roots is more precarious if you can't tell which root comes from which tree. Couple of years ago I converted a 5-tree forest to a 9-tree in a bigger pot (not oaks though) and the most time consuming part was separating the original 5 and pruning their roots. Hope that helps!
Thanks for the reply, my oak is on year 2 now has buds and some leaves are just opening now. It's inside because I thought I had lost it this winter. Is the best time now then?
@@samjohnson3170 now yes. The later you leave it the more risk it has. But at this time of year you'll need to leave it indoors to avoid the frost freezing those lovely new buds, until there's no chance of frost outside. 👍🏻
Dave, amazing as always! I planted a bunch of seeds this year so this video will be great for next year! I have a question about 1 year seedlings (if you have the time): I have planted a lot of seeds (oaks, acers, zelkova, some others), into shallow seed trays. Now that they have germinated, do you recommend slip-potting them in slightly larger, individual pots? Or can I leave them together in the shallow seed tray for the remainder of the season and put them in individual pots next year?
Thanks so much Oyens! There is so much long-term pleasure in developing your own trees from seeds. My advice is, carefully move them into indvidual pots now while it's still spring, with granular soil to get the the maximum chance of fine-root development. Like you saw in this video, even pure vermiculite will be good enough, or perlite. Perlite is great, but too lightweight so I've found mixing it 50-50 with a heavier component like any of akadama, pumice, leca/expanded clay, or turface in USA (not available here in EU). If you leave them in the seed tray until next year, it would probably be okay but the roots will start to intermingle and you just make more work for yourself untangling them next year. Also, in general it's better if your tap root goes directly downwards, rather than twisting and going horizontal. If it goes straight down, you always have the option of using some part of the tap root as your trunk. HTH.
@@BlueSkyBonsai Thank you so much for the answer (and such a thorough one as well!). Luckily I have both vermiculite, perlite, akadama, pumice and lava rock (plus sifters!). So I will go on to carefully repot my oaks this weekend and slip pot my zelkova in a slightly bigger pot since they are growing very well. My acers I will leave them alone since one of them is very weak since it germinated early (february!). Once again thank you and keep up the great work!
Looking for a bit of advice - I planted some acorns in small pots (5" diameter - one acorn per pot) and just watered them. Twenty two years later they are about 1.5 meters tall and for the first time they are not looking too well. Should I plant them out (in the woods) or just move them onto bigger containers? I'm in the Midlands in the UK. Thanks in advance : )
Ground or bigger pot... depends how soon you want to turn them into bonsai (assuming that's your plan). If you want to trunk chop quite soon then I would recommend slip-pot them into bigger pots with granular soil, and try not to disturb the roots. It's possible that they are suffering because they are badly potbound. Right now in autumn is a bad time to do any root work on oaks, I have accidentally killed an oak by repotting too late in the year. But they should be fine if you transplant without pruning roots. If you are considering waiting another 5 years before bonsifying them, then maybe they would do better in the ground. Either way you are eventually going to need to do very significant root work (early springtime) when you do finally want to train them as bonsai. And I would recommend not in spring 2022 but let them recover for a year first. Good luck!
Thanks for the suggestion! I will add it to the list of future video ideas. Although I have to tell you, the list is getting quite long! Which is a good position to be in. 🌳👍🏻
Hii! So, just wondering about pests. Like, my oaks have got something on their leaves, I think. But I can't see any animals, though. Just like, slight small spots, and some white fluff on some on them. Do you know what this is, and how/what I can do about it? I sprayed with some pesticide I had at home, but I don't know if that's the right thing to do. Is it just normal, since they're outdoors (I guess) or should I be better with feeding nutrients of some kind? (What kind?) or how often I spray their leaves? Or shouldn't I do that? Aah! XD
Hej Syster Yster! The white fluff might be caused by mealybugs, which have a waxy coating and repel most insecticides. I've had them on a juniper and on a dwarf jade, and on a pomegranate brought by ants. The best way to get rid of them is to get a cotton bud, dip in surgical alcohol and dab them all off. The alcohol gets though the wax and the critters die happy. Another natural method that works (as long as ants aren't involved) is to get several ladybirds and put them in the tree. They stay there and feed on the mealybugs. Ants are bad, they actively farm the mealybugs and consume their excretion! The other possibility if your trees are permanently warm and humid, is it could be fungus. But I guess not. Mealybugs have about 4 or 5 stages of metamorphosis and the first stage are like minuscule white dots the size of pinheads. Alcohol does the trick, variously. 🍻😁
@@BlueSkyBonsai Hmm, I can't see any bugs on them. I've looked and looked. I'll look again just to make sure though. But we have had a stupidly warm and humid summer so far. Maybe fungus then. It's like raining every other day right now, but still stays around 20'C warm. This summer is weird. We can even pick chanterelles (mushrooms) already, like 2 months too early. The birches are growing like crazy though. XD If it's fungus, what do I do about it?
Do you mean the Pyrenean Oak at 3:10 ? The soil was 100% vermiculite. It's good for one year only then decomposes to a mush. So you can use it for seedlings for 1 year but not good for establisted trees that you leave in a pot for more years.
I didn't do a video update because I didn't get enough good footage, but I took a few photos of how some of them look now. If you're interested you can see them in this flickr album- the last 12 photos are from March this year, removing some of the tourniquets and inspecting the roots: flic.kr/s/aHsmJ7vVRq
Wow, that turned out great! Excited to see how my roots look next year and I will for surely use the tourniquet method on it if needed. Mine is Coastal live oak from California, guess they are slow growers but I plan to make a shohin out of it one day if possible. Just happy one took off from see last year
Slow growers can sometimes be better for bonsai in the long term, because once they're in refinement stage they need less work than trees like common elms which need more frequent attention. By the way, the tourniquet method worked on about half the seedlings but not on the other half. Some of them continued to grow the tap root fatter underneath the tourniquet, which then bulged and met up above the tourniquet, enveloping it almost completely. Some of those could be salvaged but one or two were completly unusable. My takeaway from this, (and yeah perhaps I should have done a short video update...) was that for the tourniquets I should have used a thicker wire, and wrapped it round the tap root 3 times to ensure the lower growth could never meet up above the tourniquet. I also should have planted them deeper because a couple of them had become uncovered to the level of the tourniquet, meaning they couldn't produce new roots about it. Hope that helps you with your Coastal live oaks - good luck!
Ps. I encourage you to plant several more live oak acorns again this year! in my opinion there is too much risk and hopes on only one seedling. Y'know, if you have 10 and one dies, not too big a deal, but if you have one and it dies.. enough said!
Yes it's possible and good for the trees. If they are deciduous oaks you need to let them get cold (below 10 degree C) for a couple of months each year so they can have a dormant period. But several oak species can keep their leaves and survive 20-30 degrees all year round, like holm oak (quercus ilex), cork oak (q. suber), Portuguese oak (q. faginea).
That sounds a lot like the konara oak - quercus serrata. It's deciduous. They're from east asia and quite rare in the west. I would love to get my hands on one! Look after it well!!
hi these may be silly questions but many videos assume the viewer know thing these are the questions i have do all bonsai need wires which ones? most bonsai creators never mention wires you barely do why? are wires just a alternative from cutting the tree to encourage it to grow in the desired shape? is a bonsai different to a regular as in are they just smaller with more restricted growth or is there a biological difference?
GREAT QUESTIONS Felix, thnx for asking. Not all bonsai need wires. But they are useful when you're developing a desired style and your tree grows naturally in the opposite direction, for example most trees grow branches upwards but on an old, full size tree gravity pulls those massive heavy branches downwards so in a small potted tree we often need wires to achieve the appearance of heavy branches. I often use guy-wiring which you can see in the second half of this video: th-cam.com/video/krYT4OWRkUw/w-d-xo.html I don't like wiring the trunk because that does make the tree look false, like a typical shop bonsai. And the wires often dig into the bark very quickly, leaving a spiral scar that stays on the trunk bark for years after. Bonsai are real trees; not some special dwarf species. We use frequent branch pruning and yearly or 2-yearly root pruning to keep them small and encourage small, in-proportion leaves. In this video I talk a lot about the pruning techniques and how to make a bonsai appear like a tiny version of a big tree in nature. th-cam.com/video/cOGAJ5iqWfk/w-d-xo.html Hope that answered your questions!!
All good - thanks. Last year I sold some and sent some to bonsai friends, but the remaining ones are looking good. I recently did the year-4 repots and removed the tourniquets. I'm not doing a video on them this year, but if you're interested you can see some that I removed the tourniquets in the last 12 or so photos in this album: www.flickr.com/gp/davidhseymour/bWTZ0eUNm7
@@Ad_DOOM I removed the tourniquet on most of them, at the same time as chopping the remaining tap root. But some of them had the tap root grown completely over the tourniquet and unfortunately that meant The tap root continued to grow side roots so on those few I put another thicker tighter tourniquet for the next 2 years.

Most countries and states have laws about digging up trees, we need to get written permission from our local authorities. If you have the permission, then try to keep as much of the roots as possible intact because a lot of trees taken from the wild die in their first few months due to sudden root loss.
@@derrickjoe1872 I concede there is a difference between British and American pronunciation, due to our historical relationship with France.

Hi Dave. could you make a video about how you got started with Bonsai? what were your initial difficulties? how did you manage your space, tools, learning curve...?
Thanks Edinborogh, great idea. I wish I had more time to do more videos. I've got one coming soon about shallow pots then another one in the queue about a 9-tree forest planting. Then I need to do some early summer pruning.. and space is still an issue... hahaha I think I'm saying I have more difficulties now than I did initially!! I think I don't yet have enough subs to do a personal story, but it could work to show the challenges and setbacks, and how I overcame them. The biggest one is about tree deaths!
A really good interesting video Dave, fantastic editing, I appreciate the sounds effects and photography! Those Oaks are going to grow really well in the new pots and soil.
Thanks Nigel, I really appreciate your kind words. Yes when they grow bigger the pyrenean oaks are very pretty, especially with their tightly spaced small leaves.
The difference in soil is really showing! That’s an excellent tip 👍🏻
Yes-like night and day! 🌳👍🏻
It would be interesting to see the year 3 of this oaks, it's time for it Dave 😝
Thanks ! I'm flattered that you would be interested... but this year the video would be like 30 seconds long! Basically they're all still in these grow pots for this year, thickening up. Next spring I'll do a Year 4 update, if all goes to plan. The seedlings in bigger white pots will stay in their pots until year 5 but all the oaks in smaller black pots, I'll repot them into the white pots. It's also a chance to inspect how the roots are getting on, and hopefully remove the rest of the tap roots.
@@BlueSkyBonsai awesome! I'm interested in learning how to develop a future bonsai from seed/seedling and I think this series has a lot to offer on that department! I germinated one european oak (quercus roble) and one cork oak (quercus suber) which grew absolutely huge just these season (~60cm)! I will rewatch this video to cut the tap root next spring!
Greetings from Porto!
At last, a no nonsense straight to the point (no waffling!) How to TH-cam.
Much appreciated 👍
Thanks, glad you found it useful!
Brilliant trees and I love the oaks. Thank you for sharing 🙏🏻🕉️🎋
Thanks! I also love oaks, they have wonderful leaves and make great bonsai
Great idea to use the tourniquet on seedlings. I’ve used that process to fuse clumps and to eliminate reverse taper. I Never used it with seedlings but I will now. No wonder many of my seedlings don’t make it. Thanks
Cheers Matt! Yep, I noticed a few years ago that some of my seedlings withered beyond revival after I chopped the tap root, and others just didn't bud out until mid summer when there's less of the growing season left to grow. So tourniquetting and taprooting over two years seems to avoid that risk. I wonder why oaks seem to tap much thicker than other trees. It's also, I guess, the reason why I have never successfully kept oak yamadori alive.
Hello blue sky bonsai! Nigel Saunders tipped me off to come check out your channel I think I might be interested in some oaks now. keep making the great videos
Cheers Dave, it's always nice to see other Daves out there! 😊 I've just subscribed to your channel!
@@BlueSkyBonsai Bonsai on my youtube friend. Look forward to seeing more of your trees in. 2022!
@@DavesBonsai happy new year!!
I’m so excited for you and your new Oaks, Growing from seeds like a pro! You shared advice with me several months back on the Oaks seedlings I found in my yard most likely from squirrels. I dug them up, clipped the tap root, which was about 16” long! They survived the freeze if the century we had this winter and budded out! For the third one that was much bigger, I dug down about a foot on one side and cut the tap root and placed a glazed square tile under the cut portion and covered it back up. I’ll let it be for the summer and dig it up next year . You mentioned it might be harder to transplant since it was much bigger and I thought this might be an interesting way to deal with the tap root. It seems to be doing well, new leaves look happy! That you for your advice and feedback! I most likely would have let them grow far too long in the ground had you not suggested digging them up. I also like the idea for using the wire to slowly choke off the long tap root. As always, I appreciate your videos and the care in which you take to provide such helpful information! Cheers to another growing season and the fun it brings!
Thanks so much! I remember it well; I'm so happy yours have budded out and are doing well. They will make fantastic bonsai in the future. It's a great plan to plant a glazed tile under the roots - that will make it so much easier to pot up in the future. Cheers! 🌳👍
I just found an oak sapling, but I didn't know how to turn it into a bonsai. Thank you, your video was very informative. Now I know what I need to do.
Great! Glad you found it helpful.
I like the style of editing. Very interesting and informative - I'm straggling myself with tap roots and this video helps a lot.
Cheers Edinborogh! Yes the tap root can be horrendous in some seedlings. But it does help to think there's always another year! you can deal with it over 2 or even three goes if necessary. Glad the video helped - thanks!
Very interesting and plenty of clear information. Now to practice!! Thanks a lot
Thanks! Have fun!
You’ve again given us a great summary on a specific tree. I’ll be using it to rehab our Burr Oak. Your oak seedlings look to be very interesting, and should become a prized bonsai.
Thanks Jeff! yes I think the oaks all make wonderful bonsai, I have five different species developing -- two you saw in this video, and also Holm oak (aka holly oak), Cork oak, and Portuguese oak. I haven't seen any Burr oaks here in Europe, but looking at pictures of them, they look fantastic full size. If you can reduce the leaves they would make super bonsai. I also like the look of pin-oak leaves but I think they are just too big; not sure they could be reduced sufficiently for a convincing looking bonsai.
Good and simple tips for growing oaks from seed. I especially liked the comparison you made at the end regarding growth in different soil types. 👍
Thanks OB! Yes if ever you are considering what to use as potting soil for seedlings or any plants... that 16-month like-for-like comparison is clear enough for me. Cheers!
@@BlueSkyBonsai You can't get a clearer proof for the benefits of granular soil!
@@OddBonsai yep! Also there's a lot to be said for trying it out yourself and seeing the results first hand! I was surprised at how well the vermiculite worked on its own, but, it was much stickier and trickier to get off the roots than akadama or cat litter.
Good stuff man. I have nine acorns that have been rooting for the last month and have started to sprout above ground. This is my first ever attempt at bonsai (let alone oak bonsai), so your directions are invaluable for my confidence going forward.
Thanks Zachary, good job rooting the acorns, enjoy it!
Mini bonsai aNice and beautiful 👍🙏
Yes 🌳👍🏻 thanks 😊
Love the attention to detail!
Thanks so much!
Wonderful video Dave! All of your vids are informative but I found this one especially helpful! Thanks.
Thanks Gary! Glad to hear my videos are helpful!
What a wonderful video. I have two English oaks grown from acorn, about 4 years old now, and they're doing well, although I think I need to reconsider the soil as I feel the trunks should be thicker by now. The diameter of the larger of the two is about 15mm at its base.
@@jgp9260 thank you!
I have seen that the English oaks like to shoot up fast and high before the trunk starts to thicken significantly. They grow faster in the ground, which I think is because oaks push down a massive thick taproot, which they can't do in a pot. Of course the disadvantage is then it's much harder to uproot then tame the root system. So I griw mine in deep pots.
What soil are you using? And are you fertilising sufficiently? Also, how deep are the pots?
Good video Dave
Thanks Nick!
this is exactly what i was looking for! i killed two oak trees this year from chopping the tap root and not leaving enough fine roots. i won't be making that mistake again next year. got several oaks that are just germinating ready for spring.
also, love the bench. watched the video where you built it and i think i'll have a go ready for this summer
Sorry to hear about this year's oaks. I have also lost several oaks in the past, tried to take some as yamadori and they all died. They are pretty sensitive if they don't have enough fine roots.
When you start on your benches next year drop me a line and I can give you an update on mine, what I'd do different next time, etc.
Great information and really well presented. Thanks much.
Thanks a lot, I really appreciate it!
Very informative and well done thank you. I am fairly new to Bonsai and appreciate your channel.
Thanks and welcome to the rewarding (and addictive) world of containerized trees!
Oaks love a tap root! the tourniquet is a great idea on how to deal with them. much better than the extreme chop and hope it survives method
Cheers Ian! Yep - and amazingly a few of the seedlings I decided to tourniquet have already wilted substantially in the hot sun, so I'm really happy I didn't just do the chop and hope because I'm sure they wouldn't have survived. Hey maybe they still won't make it through summer! 😂
@@BlueSkyBonsai yeah imsure they will bounce back in no time
Great video, as always
Thanks BA! 🌳👍🏻

I want to create a photo garden blog with photos of our garden but couldn't yet think of a fitting name, haha.
Kind greetings
@@Dispatern it's getting quite late in spring by now to prune the tap roots. If it has already grown several large leaves then you might be risking killing it to prune off the tap roots this late in the season. You could still do the torniquet part only now, then do a more severe root pruning next spring in early march??
Ps. Good luck with your blog name!
@@BlueSkyBonsai Thank you for the advise. I'll prune the tap root next spring then. Is it okay to prune the tap root of 3 year-old trees or would the ideal time have been in the second year? That's something I'm confused about.
(I've got a green thumb but I'm fairly new to the wonderful world of Bonsai.)
Thank you! Every project starts with a name :)
Have a nice weekend and thanks a lot for your tips. I appreciate it.
@@Dispatern it's okay to prune the tap root year 3 as long as there are plenty of fine roots still attached to the trunk (ie above where you prune). And as mentioned do it just as the leaf buds are swelling but before the leaves have all started to extend.
Hi Dave, my oak tree is still alive and the bonsai uswell, I am happy for that. I hope you can see them soon.
Hi Isa, that's great to hear! I'm also happy for you. Are you going to be brave and tourniquet your tap root? Or will you wait until we can visit next??
@@BlueSkyBonsai I will wait :)
@@isabelcubria370 ok! I'll bring some binsai soil when we come. Whenever that may be!!
Thanks for the video! I collected some monterey cypress cones a couple months ago and some of those seeds actually germinated! Unfortunately two of them died but I'm hoping some of the other seeds start to germinate as well. I haven't started any bonsai from seeds yet so it'll be an exciting endeavor if I can get it started.
Thanks Garrett! That's why I always recommend planting many seeds, because some wil always die along the way. Growing them from seeds is really special, because you did everything to the tree from before it even became a tree. Good luck with the remaining cypresses!
ty for teaching me so much so shortly, with all your vids! my trees will thank you too, ive been torturing them with wrong trim times and wrong root pruning times. how have my trees suffered. idk how they survived....dam i just need to keep them healthy in a pot b4 i think about actually learning how to prune and the right time....slowing learning the art, trying to rush bonsai is a lost cause...
You're welcome, and, you're right to see that you can't rush bonsai. Part of the beauty of it is in the long term development and seeing your work from 5 years ago come to fruition now!
Some trees survive much easier than others. Elms and ficus for example seem to survive all kinds of chopping and hacking! But at the same time, it's inevitable that we will lose one or two trees along the way. What trees do you have?
Booom!!! Great video. I have had the tap root issue with trident maples, and London plane trees. This turniquet idea is amazing. I never would have thought of that. The tap root makes repotting terribly difficult with seedlings. Im going to use this technique in the future. Thanks broski. 😎🍺🍺
Cheers Broski!! Glad you liked it.. the tap roots have to be dealt with of course, but, if that threatens the survival of the seedling then it defeats all the work you've put in so far. Actually a few of the seedlings that I tourniquetted have already wilted a bit in the hot sun, so I'm double glad I decided not to completely chop the taps. Ps. Madrid out against Chelsea last week, did you see the match? Madrid's defense was worse than nomal, so it was almost predictable result, but my son was really sore!
Is it possible to plant in vermiculite, without soil? Do I need to fertilize something? Thank you for the video!
Yes, at 3:08 you see this was grown in 100% vermiculite and it grew really vigorously. For acorns you don't need to fertilize in the first year, but from the second year I recommend fertilize every two weeks from Spring through to autum.
You never let us down with the quality of your video and information. I love dealing with oaks and that tap root is the problem we all must face...at some point. in my growing beds I undercut once a year to ensure the tap doesnt go to Japan! I had never heard of the tourniquet method and I wish I had. I presume ti would work as well with some of our other species - hawthorne, Larch and Hornbeam? Thank you.
Thanks Xavier! One of the things I love about oaks is their lovely leaf shape, but at the same time those leaves draw up tons of water from the roots. This is why I find it safer to tourniquet the tap and deal with it over 2-3 years rather than a "Hail-Mary" "chop and hope". I have lost 2 oaks (that I can remember...) due to severe root pruning too late in spring when the big leaves are already demanding lots of water.
I have also tourniquetted Japanese maples, sycamores, mulberry, anything with bigger leaves that risk dying of thirst after a tap-root chop.
Elms and hornbeams can take quite a heavy root chop and survive ok - I haven't bothered tourniqueting them. Never tried it on a hawthorn (I don't have any) but Larch - I have one thickening up in a deep grow pot so I will inspect the root system next spring and decide whether to tourniquet it.
There is a potential downside to the tourniquet. It can give lopsided or uneven radial roots. My biggest Japanese maple in a grow pot still has its tourniquet but I can't really use the resultant roots: one is so much bigger and thicker than all the others. And there is a big gap. So I will have to tourniquet again above the roots or do a full ground layer next spring.
But for oaks, it's still better to do this than continue growing the massive tap root and sending out feeder roots 30cm under the trunk base...
@@BlueSkyBonsai thanks for such a detailed and useful response. That will all go onto mt tree notes for reference.
Thank you!
@@ProfWisecrack you're welcome 😊
Very interesting, I'd love to see the root development after the tourniquet! I'm starting with some pines, I'll be lucky if I get that much growth after a couple more years.
Thanks! I'll be sure to update in the future. Good luck with the pines!
@@BlueSkyBonsaiit’s been 2 years, have you already repotted these?
@@Augustinion yes, I did it in spring this year, but unfortunately time ran out and I didn't make a video of it. Luckily I took some photos, if you're interested you can see them in this album: www.flickr.com/gp/davidhseymour/2t571HB25q
-you need to scroll down a bit.
I repotted them into the same deep grow pots, to keep thickening them up for another couple of years. If I get more time next spring I'll do a video. Maybe take a few out again and inspect, with a kind of "what worked and what went wrong" angle, maybe lessons learnt.

Thanks Raphael! Glad this video met your expectations.. and was relevant to your oaks.
You've picked two great oak choices to develop. Of course the English oak is deciduous, but the cork oak is evergreen - they have wonderful small leaves a bit like holm oak but a deeper green and less spiky. I have two corkers, one is two years old (i.e. in its third year) and the other only 1 year old. They were both out all winter, so we know they can withstand snow and sub-zero temperatures for a significant period of time. Just saying, because they are most common in southern spain and portugal where they don't get much freezing temperatures.
Haha the wine sounds good, I also drink beer by the gallon!
I plan to leave my english oaks for several years to get bigger and fatter, but some of the pyrenean oaks I will probably start to bonsify sooner because they are slower growers and have smaller leaves. It's also the advantage of planting many acorns, like you did-- you have a lot more options each year for deciding whether to bonsify or continue trunk development. I'm not too keen on wiring seedlings. On one hand, now is a great time to do it, but on the other hand if you leave that wire on for just a few weeks too long, and you'll have the tell-tale spiral wire mark for many more years .. the growing bark takes a long time to forgive and forget! Maybe I will wire just a couple of them for interest but the best bet then is to unwire and rewire each 4-6 weeks, to avoid the scars. Too much effort for me, especially when you're also watching dozens of other trees. Anyway, yes, I'll continue to track these along with some of my other developing trees.
And now re-reading my reply here, maybe the subject title of my future pre-bonsai development video could be "to bonsify or not to bonsify", I believe I might have invented a verb here unless someone has already coined it. 👍🍻
@@BlueSkyBonsai if people know what you mean, it's a word. And Bonsify is clear to me!!
Hi Dave, this David from Australia,, last year I planted 6 tulipwood and cassia fistula ( golden shower) in peat moss, all sprouted but looks a little weak. This spring I'll use your advice and plant more seeds in a more efficient mix
Great stuff David, the key is drainage so that every time you water them, a pot-load of air is also sucked down into all the pores in the soil which is essential for root health
I didn't know you lived in Spain! I agree, the sun in mid summer can be really harsh on plants, specially down here in Andalucía.
Hahaha yes, lived in Madrid for over 20 years, I drop it into a few of my videos but this time I said it right near the beginning so you couldn't miss it!
In a week or two I will be attempting to construct some kind of semi-shade over the bonsai benches. Some trees love the strong sunlight, like the oaks and elms, and of course olives love full-on direct sunlight. But my Japanese maples seem to get leaf burn every year and it's not for lack of watering! Azaleas suffer too. Cheers Edu!
@@BlueSkyBonsai yeah, i just got a couple of maples and was just thinking about doing the same, but for now I'll just keep them in a shaded area. Take care!
@@PSPMHaestros thanks! Hey it's a tricky situation though, of course they need sunlight to grow, and in the shade they sometimes develop bigger leaves. But bigger leaves are better than burnt leaves, given the choice.
Wonderful info .. thank you! Wouldvthevtpurnaquette method work on bald cypress?
Thanks! I don't have any bald cypresses, they're very rare in Spain. So I can't say from personal experience.
If you do try the tourniquet method, there are a few things I've learnt since this video. 1, use a thick enough wire to ensure the bark doesn't callus over the wire, and wrap it 2 or 3 times around the trunk.
2, remove ALL roots above the tourniquet, otherwise they will grow much bigger and thicker than any new roots.
3, Bury the tourniquet deeply enough in the soil so that the new root plane you want doesn't become uncovered.
Hope that helps!
Great video, any chance we can get the follow up, like the trees health and how to help them along, I just replanted a few cuttings and another small yardadori and they seem to lose some leaves when I transplanted them from potting soil into an akadama mix.
Thanks Robby! Not sure if you already saw this video about ensuring your cuttings take root: th-cam.com/video/RnGfUeQC7r8/w-d-xo.html
For a few weeks you need to have the cutting in an incubator or propagator to keep the humid at 100% to keep the leaves alive.
Also, keep the pot resting in a shallow bowl of water for a few weeks so that the akadama stays wet. You can do this with a cutting to encourage roots, but not a seedling that already has roots because you have a risk of the water stagnating and then possibility of root rot in that water.
Hope that helps!
Verry interesting👍👍🙏🙏
Thank you! 🌳👍🏻
Sorry if I missed it, making lunch while listening... do you have any pics of the tourniquet results?
No, sorry Darren for some reason I only took video, no photos. The thumnail is from a screen capture during the video.
Or did you mean, how the roots have grown above the tourniquet 1 or 2 years later?
@@BlueSkyBonsai yeah the 2 years later stage. I have some growing through CDs but they aren’t ready yet. Impatient to see what I might find
@@grobonsai same, I have some oaks and JMs with tourniquets but they're stil buried.
Have you read Harry H's 'Inspirations' books? He has some good pictures of his touniquet results in ... can't remember if it was book 1 or book 2. I'll have a look now.
Love your videos. If your doing this to the seedlings in the spring. Wont the seedlings die?
Thanks Chris!
I did this last spring to over 40 seedlings, and only 1 died. I did it slightly too late in spring - the leaves had already opened up on most of the seedlings. The best time is just before the leaves unfurl, when the leaf buds are really swelling and ready to pop.
Very good explanation Dave. I know this method can be used to air layer certain species but wondered if you can use this to grow an entirely new root base further up the trunk on a more mature tree?
Thanks Toby! I have never tried a touniquet on the main trunk. I'm not sure it would work. One of the risks of air layering is that the bark starts to callus horrendously and that's why it's important to cut the layer right through the cambium and leave a sufficient space bare so that the callusing can't hinder root growth. So I think to use a tourniquet alone, the trunk would callous over it. I think you'd need to combine it with the cut layer. I might be wrong though...
На ямадорных деревьях я не укорачиваю стержневой корень, а разрезаю вдоль на 4 части, раздвигаю крестом и фиксирую в грунте. Желаю удачи.
That sounds like very good advice - thank you!
Hello again! I had already seen this video apparently. :D But I had forgotten the term for tying the root. :)
Hi! Well I don't expect you would remember all my videos!! But it doesn't hurt to see them again 😉😂
@@BlueSkyBonsai Absolutely. :P I like watching them anyway. :)
I always try to cut the tap root in the first year, ideally after it started growing. That way much more of the acorns energy can go into the fine roots. It will try to create another tap root though sometimes.
@@54114142 sounds good if there are enough fine roots remaining above your chop!
@@BlueSkyBonsai you don't need any if you do it early enough because the acorn supplies the tap root with energy and will push out fine roots just faster and more vigorous if you cut it at this early stage.
Hi, I chopped the tap root last year, unsure how well I did as I've never done it before. In your video you say to wait about 2 years but should I check again this year to see if I need to do any more cutting?
Hi, It depends on the species - some root much faster than others, e.g. oaks, wait 2 years, but elms, 1 year. What tree is it?
@@BlueSkyBonsai hi i presume it's an English oak. It's an oak tree I found as a baby when out walking
@@sarahrhi82 even if you don't prune the roots now, Spring is a good time to lift it out of the pot and inspect the roots. So you can see if it has rooted prolifically and there are loads of fine roots coming from above the tap root, that's your chance to cut the tap root further now. But if you're not sure, leave it another year. Patience is the key in bonsai!
@@BlueSkyBonsai thanks, great I was hoping you would say that.
Any chance for an update...? Would love to know how the results turned out. ❤
Good call! Yes I do want to do an update on this - let's see if I get the time over the coming months now my book is finally finished and published!
In summary, many of these tourniquet jobs turned out great, but a few of them failed. You can see some results in the last 10 or 11 photos in this album: flic.kr/s/aHsmJ7vVRq
The few failures were caused by three different issues: 1. one wire was too thin so the tap root callused over it and continued to grow. 2. Another tourniquet was not buried deep enough so the wire became slightly uncovered, and again the tap root continued to grow. 3. The ones where I left a root growing above the tourniquet, they didn't fail but got a new problem - the root that I left grew much bigger than any of the new roots, disproportionately big, so I had to remove that. You'll be happy to hear that these failures and how to avoid them, are documented in my book!
I have a very small oak 6-7 inches , with two leaves. I dug it up and potted it so I could 'look after it' but having seen your video I think I've probably stalled it as I put it in a pot with something like miracle grow compost. It's ok but seems to be very much in slow motion a year on. It looks like I should change it's soil for??...vermiculite?? Please can you recommend what to do as it's now getting sunny here in west wales and its starting to leaf but incredibly slowly. I'm 53 and I'd like to see a bonsai of it in my lifetime if I'm lucky 😂. Many thanks 😎
I wouldn't recommend vermiculite because it gradually breaks down in the winter freezes - I did it on this on tree as an experiment. Much better soil would be:
Akadama if you can get, mixed with tiny chopped pine bark and pumice, all seived to get rid of the dust.
The reason for using granular soil (instead of compost) is to allow good drainage and to continually get oxygen down to all the roots every time you water.
Get rid of the dust before potting so that it doesn't clog up the pores in the soil and the drainage holes.
HTH
Ps. 53? You still have a long life ahead of you!!
Just found your video. Great information!! I've started a Holly Oak (Quercus Ilex) about 1.5 year ago. Would this apply to that type of oak as well?
Hi, and thanks!
Yes same applies to q.ilex too. I have four holm/holly oaks from acorns that I collected near my house and planted in autumn 2017. I used the tourniquet trick on them when I moved them to bigger grow pots 3 years ago. If you're interested they are in my holm oak album in Flickr here: www.flickr.com/gp/davidhseymour/i8173e
The last photo in that album was Nov 2020 so I probably better take some new photos... they are already quite a lot bigger now. I am considering turning one of them into a small bonsai already. I'll need to transfer to an intermediate pot first to train the roots and start developing nebari.
That seedling on 6:38 you could also place the tree higher up and remove those few fine roots, you would have a bigger trunk to start with. At least that would be my choice.
Yes that's a good option. The issue here is that I left it too late in the season to do serious root work and I needed leave a lot of the fine roots on. As it is, some of the trees have lost their leaves as a result of the root pruning and hot dry Madrid air. They'll survive, but I should have done this job back in early march...
Love your channel
Thanks Andrei! Now you say that, I regret not doing a close up of the different leaves. On the good side, I took some pics last year and started an archive on Flickr here: www.flickr.com/gp/davidhseymour/446xb8
I don't have any downy oaks though, but I hope this comparison helps to some extent.
@@BlueSkyBonsai Thanks for sharing :)
Thanks, i loved the tutorial. I have 2 oak trees, I'm not sure how old they are, look about 1 year. Shall. I transfer them to 100% vermiculite? and if roots look good do what you recommend in video?
Thank you!
It depends where you are. If you're in the northern hemisphere, you should wait until early spring next year. Oaks don't respond well to root work in the heat of summer.
If you're in the southern hemisphere then you're nearly at the right time to do it, as soon as you see the buds swelling, go for it!
Vermiculite worked well but it starts to break down after a year or so, so if you can mix it with perlite or pumice then it should hold its structure for a couple of years. If you can get hold of some akadama then that would work great.
@@BlueSkyBonsai many thanks. I'll do it next spring then, I'm in sunny England. 30 degrees today
@@sarahrhi82 sounds fresh! 😁 38 in Madrid today due to keep rising during the week 🥵
what do you use for soil? Not sure if its just because of trying to ship things with covid everywhere but its very hard to get akadama here. I am trying to figure out what to use for my trees. Thanks for the video!
Try perlite and turface 50/50, seived to rdmove the dust and fines. I prefer pumice to perlite but it's rare to get pumice in 4-5mm particles. Perlite is a very good alternative, but is very lightweight and I prefer heavier soil because it's very windy where I live.
@@BlueSkyBonsai thanks for taking the time to answer questions, I really appreciate the advice!
Has anyone ever told you that you say “tourniquet” exactly like Roger Waters in “One of my Turns?”
I have to admit that I like those gnarly little twists that sometimes happen between tap root and trunk after a seed germinates. Are you just thinking that they wouldn’t work with oaks since they should be grown in an upright/ informal upright style?
Cheers man, killer vid.
Thanks C., funny you should say that... most Brits pronounce it in false-french like "torniquey" but I decided to go for the mid-atlantic pronounciation with a hard T on the end. That, and Roger Waters is my dad.. no he's not, of course. Roger Waters would be great nominative determinism for a garden assistant ("Do you know Roger Waters? No, but thanks for the tip!")
Regarding the curly tap root, I kept a couple of them like that, and exposed the twists above the soil like for a bit of fun. I think a tap root with a modest curve would be fine to use as a trunk, but most of the twists were too severe in stark contrast with the straight trunk. Btw, still planning on sending you a couple of them, I'll let you know when they're in the post.
@@BlueSkyBonsai OK so I went back and listened to the song (it had been a while) and sure enough, he says "torniQUEY", all Frenchy-like. Unreal, as I'd always sung it (and heard) a hard "T" when spinning the cassette that I ripped from my CD so I could play it in my '84 hatchback Accord.
Also I've googled "nominative determinism" and now understand your Waters joke. Very clever, David.
Yes I'm sure the degree of twisty insanity would determine whether that part of the trunk were usable or not...good call. It was fresh in my mind as the same thing just happened to me when repotting a hornbeam (hopefully you'l see that soon).
Send what you will, though I am undeserving.
@@BostonBonsaiIdiot For interest: About 40 years ago my dad went into a serious depression after he listened and investigated the lyrics of The Wall. Since then I've never really wanted to get into it! except of course the songs are still on the radio all the time... But if I listen now to Dark Side of the Moon I get massive nostalgia from my childhood.. same with Beatles and one or two others. Now I'm showing my age ...
@@BlueSkyBonsai There's something about the tone of that record that's mysteriously jarring. Add to that the subject matter, and the fact that your dad is British and of a certain age...perfect storm. I totally get it. Luckily, you brits have all the other greatest-rock-bands-of-all-time to fall back on, so there should have been no shortage of musical enjoyment in that house!
@@BostonBonsaiIdiot all true, but I also have to say one of my all time favourites was Simon and Garfunkel, that beautiful music was often wafting round the house in those years and I still love it now. And you had Elvis, and Roy Orbison. So it's six of one, half a dozen of the other...?
Hi Dave, i can't wait until spring to cut my tap roots. I was just wondering, you suggested potting in 100% vermiculite, do you need to feed it? Could I also use lechuza pon?
Hi Sarah, if you use vermiculite or any inorganic granular soil, yes then it's a good idea to fertilise at least every second week. However not straight after repotting/root pruning... let it recover for 5-6 weeks before fertilising.
Lechuza pon, never tried it - it looks ok but maybe you need more water retention in your soil - it depends on your climate. Here in hot Madrid that would be too dry too quickly. If your climate is cooler and wetter I guess that substrate might work. But again, not great to use fertilizer straight after root pruning trees in containers ... I see lechuza pon already has fertilizer ingredients. Maybe you could try it for one seedling, and vermiculite for another, then compare the results after a year?
@@BlueSkyBonsai thanks so much for reply. Yes I may do that or mix a bit of the lechuza pon with vermiculite. Is there any particular fertiliser you would use if just vermiculite? Many thanks Sarah
@@sarahrhi82 sounds like a good plan. I use regular universal liquid fertilizer diluted to the amount in the instructions.
Love the video but help. Been growing bonsai for a while now. But, I don't fully understand pruning. Example, I cut a branch back and it just puts a shoot out. Now I've tried directional pruning straight cut even completely wrong cut. Just end up with a branch that goes on and on year after year. All the growth is always at the end. So I just end up with a long branch and no bi directional or finer or secondary branches. Please can you explain. I can send pics if you need. Thank you Tom.
Hi Tom, I hope I have answered your questions about branch pruning in this video:
th-cam.com/video/cOGAJ5iqWfk/w-d-xo.html (part 1)
And then part 2: th-cam.com/video/rziuv_Cdf-U/w-d-xo.html
If you watch these and still have doubts, let me know!
Also, a lot depends on the tree species. Some grow apically (taller/upwards) while others are more laterally dominant (more bush-like). Apically dominant trees can be harder to encourage fine ramification because their genes have evolved for elongation, to push up higher than the surrounding trees. But ultimately all can be encouraged to bifurcate, just some slower than others.
If you're finding only one new shoot emerges at every pruning point, prune that back to two or three leaves, then those too when they grow. Keep doing it and consider ramification a long term goal, not something you achieve in a matter of months. I really hope that helps. Above all, be patient and don't give up! 🌳👍🏻
Can I apply a cut sealant paste on the wound of the tap root after I cut it off? Will it disturb any new growth of roots from doing that?
I have never applied a wound sealant to cut roots. But maybe you could do that to make sure no more roots emerge from the cut location. Give it a try!
nice
Thanks bro!
If you cut the tap root in half, will a new extension of tap root, from the original half tap root, continue to regrow.
OR does cutting the tap root in half stop the tap root from continuing to grow.
If you cut the tap root in half it can continue to grow new roots from the end and from many points further up the root. In the ideal situation we would want to completely remove the tap root to force all new roots to emerge next to the trunk base. But in the real world that can sometimes mean killing the seedling if it doesn't have enough remaining roots to support the water requirements of the leaves. So that's why sometimes need to cut it in half and use a touniquet to limit further root growth.
I have some English oak saplings which are 8 months old. They are already 6-12 inches tall. Would you suggest leaving it another year before the tap root chop? Its probably too late to do this year.
Yes I would leave them until next spring - early spring just as you see the new leaf buds swelling. Because oaks can be a bit sensitive to root work this close to summer with their large leaf area.
Very important vedio clip
Thanks very much 🌳👍🏻
Do you water straight after cutting tap root and placing in vermiculite?
Yes! Also, if your tree already has several leaves like in this video, keep it watered and in the shade for a couple of weeks to prevent the leaves from drying due to a temporarily depleted root system. If it already has a lot of large leaves, put a clear plastic bag over it for a week or so, to virtually stop the transpiration in the leaves while it regrows new tiny roots. HTH!
I'm curious about the success with 100% vermiculite. Do you think this would produce similar results with all or most other oaks? Also, in my admittedly limited experience with live oaks, they don't usually like as much root disturbance as all lot of other trees. Is this different with tree that were germinated in containers (compared to those germinated in the ground)? Would you mind if I contact you directly to discuss as it relates to some oaks I'm currently working on?
Hi Joshua, vermiculite encourages more fine roots but it breaks down after a year, can't cope with more than two winters outdoors. So yes I would use vermiculite again for other oaks' acorns too, knowing that in the second spring I have to repot, like in this video.
Most oaks don't like too severe root work, but it's much less risky at the start of Spring just when you see the buds swelling ready to pop.
Yes you can email me if you want, dave@blueskybonsai.com
Question Dave. I’ve got 6 English oak acorns (kindly sent to me in Connecticut from @Tonys Bonsai) planted in one pot. When would you suggest separating them into individual pots? Thanks
Hi Matt, if you have the extra pots and space, I would separate them (carefully) as soon as you see the roots starting to extend more than an inch or so. The longer you leave it, the more work it is to untangle them. Even if you're planning to develop them as an oak forest, it's still easier to grow them separately for the first few years so each one gets the water and nutrients it individually needs, and so you can prune each tree's roots separately before combining them in a group planting.
Whereas, if you keep them together then you're (almost) stuck with that positioning configuration of trees. And pruning tap roots is more precarious if you can't tell which root comes from which tree.
Couple of years ago I converted a 5-tree forest to a 9-tree in a bigger pot (not oaks though) and the most time consuming part was separating the original 5 and pruning their roots. Hope that helps!

Sorry if I missed it in the video but what time of year is best to do this to your seedling, I see a lot of leaves on the plant. Thanks
Best time is indeed before I shot this. The safest time is just when you see the buds swelling ready to pop.
Thanks for the reply, my oak is on year 2 now has buds and some leaves are just opening now. It's inside because I thought I had lost it this winter. Is the best time now then?
@@samjohnson3170 now yes. The later you leave it the more risk it has. But at this time of year you'll need to leave it indoors to avoid the frost freezing those lovely new buds, until there's no chance of frost outside. 👍🏻
Dave, amazing as always! I planted a bunch of seeds this year so this video will be great for next year!
I have a question about 1 year seedlings (if you have the time): I have planted a lot of seeds (oaks, acers, zelkova, some others), into shallow seed trays. Now that they have germinated, do you recommend slip-potting them in slightly larger, individual pots? Or can I leave them together in the shallow seed tray for the remainder of the season and put them in individual pots next year?
Thanks so much Oyens! There is so much long-term pleasure in developing your own trees from seeds. My advice is, carefully move them into indvidual pots now while it's still spring, with granular soil to get the the maximum chance of fine-root development. Like you saw in this video, even pure vermiculite will be good enough, or perlite. Perlite is great, but too lightweight so I've found mixing it 50-50 with a heavier component like any of akadama, pumice, leca/expanded clay, or turface in USA (not available here in EU). If you leave them in the seed tray until next year, it would probably be okay but the roots will start to intermingle and you just make more work for yourself untangling them next year. Also, in general it's better if your tap root goes directly downwards, rather than twisting and going horizontal. If it goes straight down, you always have the option of using some part of the tap root as your trunk. HTH.
@@BlueSkyBonsai Thank you so much for the answer (and such a thorough one as well!). Luckily I have both vermiculite, perlite, akadama, pumice and lava rock (plus sifters!). So I will go on to carefully repot my oaks this weekend and slip pot my zelkova in a slightly bigger pot since they are growing very well. My acers I will leave them alone since one of them is very weak since it germinated early (february!).
Once again thank you and keep up the great work!
@@Watashiwapitadesu sounds like your seedlings are in good hands 🌳👍🏻
Looking for a bit of advice - I planted some acorns in small pots (5" diameter - one acorn per pot) and just watered them. Twenty two years later they are about 1.5 meters tall and for the first time they are not looking too well. Should I plant them out (in the woods) or just move them onto bigger containers? I'm in the Midlands in the UK. Thanks in advance : )
Ground or bigger pot... depends how soon you want to turn them into bonsai (assuming that's your plan). If you want to trunk chop quite soon then I would recommend slip-pot them into bigger pots with granular soil, and try not to disturb the roots. It's possible that they are suffering because they are badly potbound. Right now in autumn is a bad time to do any root work on oaks, I have accidentally killed an oak by repotting too late in the year. But they should be fine if you transplant without pruning roots.
If you are considering waiting another 5 years before bonsifying them, then maybe they would do better in the ground. Either way you are eventually going to need to do very significant root work (early springtime) when you do finally want to train them as bonsai. And I would recommend not in spring 2022 but let them recover for a year first.
Good luck!
@@BlueSkyBonsai That's great - thank you.
@@BoredOfBills you're welcome! I'll be interested to hear how they look in Spring
What happens if I cut a sprout (6 months old)? Will it grow back with two branches like bonsai should do or will it just die?
What species is it? Usually you'd want a seedling to grow for a whole year before starting any pruning.
Hi buddy! may i request for a video on insects etc spidermites etc if you could share any of your experience. thank you.
Thanks for the suggestion! I will add it to the list of future video ideas. Although I have to tell you, the list is getting quite long! Which is a good position to be in. 🌳👍🏻
@@BlueSkyBonsai thank you. Bad insect prevention should be top of that list ! 😀
Hii! So, just wondering about pests. Like, my oaks have got something on their leaves, I think. But I can't see any animals, though. Just like, slight small spots, and some white fluff on some on them. Do you know what this is, and how/what I can do about it? I sprayed with some pesticide I had at home, but I don't know if that's the right thing to do. Is it just normal, since they're outdoors (I guess) or should I be better with feeding nutrients of some kind? (What kind?) or how often I spray their leaves? Or shouldn't I do that? Aah! XD
Hej Syster Yster! The white fluff might be caused by mealybugs, which have a waxy coating and repel most insecticides. I've had them on a juniper and on a dwarf jade, and on a pomegranate brought by ants. The best way to get rid of them is to get a cotton bud, dip in surgical alcohol and dab them all off. The alcohol gets though the wax and the critters die happy. Another natural method that works (as long as ants aren't involved) is to get several ladybirds and put them in the tree. They stay there and feed on the mealybugs. Ants are bad, they actively farm the mealybugs and consume their excretion!
The other possibility if your trees are permanently warm and humid, is it could be fungus. But I guess not.
Mealybugs have about 4 or 5 stages of metamorphosis and the first stage are like minuscule white dots the size of pinheads. Alcohol does the trick, variously. 🍻😁
@@BlueSkyBonsai Hmm, I can't see any bugs on them. I've looked and looked. I'll look again just to make sure though. But we have had a stupidly warm and humid summer so far. Maybe fungus then. It's like raining every other day right now, but still stays around 20'C warm. This summer is weird. We can even pick chanterelles (mushrooms) already, like 2 months too early. The birches are growing like crazy though. XD If it's fungus, what do I do about it?
Thanks
Thanks for watching and commenting!
What kind of soil did you use while it was in the first pot?
Do you mean the Pyrenean Oak at 3:10 ? The soil was 100% vermiculite. It's good for one year only then decomposes to a mush. So you can use it for seedlings for 1 year but not good for establisted trees that you leave in a pot for more years.
Any update on these? 😊
I didn't do a video update because I didn't get enough good footage, but I took a few photos of how some of them look now. If you're interested you can see them in this flickr album- the last 12 photos are from March this year, removing some of the tourniquets and inspecting the roots: flic.kr/s/aHsmJ7vVRq
Wow, that turned out great! Excited to see how my roots look next year and I will for surely use the tourniquet method on it if needed. Mine is Coastal live oak from California, guess they are slow growers but I plan to make a shohin out of it one day if possible. Just happy one took off from see last year
Slow growers can sometimes be better for bonsai in the long term, because once they're in refinement stage they need less work than trees like common elms which need more frequent attention.
By the way, the tourniquet method worked on about half the seedlings but not on the other half. Some of them continued to grow the tap root fatter underneath the tourniquet, which then bulged and met up above the tourniquet, enveloping it almost completely. Some of those could be salvaged but one or two were completly unusable.
My takeaway from this, (and yeah perhaps I should have done a short video update...) was that for the tourniquets I should have used a thicker wire, and wrapped it round the tap root 3 times to ensure the lower growth could never meet up above the tourniquet. I also should have planted them deeper because a couple of them had become uncovered to the level of the tourniquet, meaning they couldn't produce new roots about it.
Hope that helps you with your Coastal live oaks - good luck!
Ps. I encourage you to plant several more live oak acorns again this year! in my opinion there is too much risk and hopes on only one seedling. Y'know, if you have 10 and one dies, not too big a deal, but if you have one and it dies.. enough said!
Is it possible to grow oak tree at a temperature of 20-30 degree Celsius
Yes it's possible and good for the trees. If they are deciduous oaks you need to let them get cold (below 10 degree C) for a couple of months each year so they can have a dormant period. But several oak species can keep their leaves and survive 20-30 degrees all year round, like holm oak (quercus ilex), cork oak (q. suber), Portuguese oak (q. faginea).
Hello do you know anything about a tree called kanora oak. I just ran across one and can't find info on it.Its in a pot. Thank you
That sounds a lot like the konara oak - quercus serrata. It's deciduous. They're from east asia and quite rare in the west. I would love to get my hands on one! Look after it well!!
Can i do this on Japanese red pine too?
Sorry I can't advise, I don't have any Japanese red pines.
hi these may be silly questions but many videos assume the viewer know thing these are the questions i have
do all bonsai need wires which ones?
most bonsai creators never mention wires you barely do why?
are wires just a alternative from cutting the tree to encourage it to grow in the desired shape?
is a bonsai different to a regular as in are they just smaller with more restricted growth or is there a biological difference?
GREAT QUESTIONS Felix, thnx for asking. Not all bonsai need wires. But they are useful when you're developing a desired style and your tree grows naturally in the opposite direction, for example most trees grow branches upwards but on an old, full size tree gravity pulls those massive heavy branches downwards so in a small potted tree we often need wires to achieve the appearance of heavy branches. I often use guy-wiring which you can see in the second half of this video: th-cam.com/video/krYT4OWRkUw/w-d-xo.html
I don't like wiring the trunk because that does make the tree look false, like a typical shop bonsai. And the wires often dig into the bark very quickly, leaving a spiral scar that stays on the trunk bark for years after.
Bonsai are real trees; not some special dwarf species. We use frequent branch pruning and yearly or 2-yearly root pruning to keep them small and encourage small, in-proportion leaves. In this video I talk a lot about the pruning techniques and how to make a bonsai appear like a tiny version of a big tree in nature. th-cam.com/video/cOGAJ5iqWfk/w-d-xo.html
Hope that answered your questions!!
thanks so much
How are these Oaks doing now?
All good - thanks. Last year I sold some and sent some to bonsai friends, but the remaining ones are looking good. I recently did the year-4 repots and removed the tourniquets. I'm not doing a video on them this year, but if you're interested you can see some that I removed the tourniquets in the last 12 or so photos in this album: www.flickr.com/gp/davidhseymour/bWTZ0eUNm7
@@BlueSkyBonsai perfect. They look great! Did you need to remove the tourniquet or did you just leave it to grow around?
@@Ad_DOOM I removed the tourniquet on most of them, at the same time as chopping the remaining tap root. But some of them had the tap root grown completely over the tourniquet and unfortunately that meant The tap root continued to grow side roots so on those few I put another thicker tighter tourniquet for the next 2 years.
Fermiculite must buy
@@RainVine called vermiculite with a V in spain... i hope it's also with a V in English because I just published that in my new book!!

It is gpod
Thank you!!
can i just steal a baby white pine on my land ? im sure i can but nut sure if its possible
Most countries and states have laws about digging up trees, we need to get written permission from our local authorities. If you have the permission, then try to keep as much of the roots as possible intact because a lot of trees taken from the wild die in their first few months due to sudden root loss.
It’s pronounced ‘torniquay’, since it’s a French word and the t is silent. Great video tho! Ty.
Thank you!!

@@derrickjoe1872 Then they incorrect
@@derrickjoe1872 I concede there is a difference between British and American pronunciation, due to our historical relationship with France. I urge you to Google ‘tourniquet pronunciation’ and you will see the two versions. Thank you for attempting to mansplain however. It has been amusing for this Linguistics BA 🤣. I could go into more technical detail but I really don’t think it’s worth my time. Have a good day.
@@derrickjoe1872 He’s BRITISH therefore he was pronouncing it in an incorrectly for a BRITISH person 🙄. I kindly pointed out the correct pronunciation for HIM. I didn’t want him to sound like he didn’t know and open him up to ridicule for being ignorant of the fact. It was a kindness, and politely done. You might notice that he thanked me, like a true English gentleman. He’s lovely and I felt protective. My degree is not worthless at all, and your personal attack suggests you feel a little threatened by people with an education. I’m sorry you feel that antipathy. I’m done with this conversation, so feel free to carry on being rude. I will not be reading or engaging. That ‘Thank you’ was all I needed. Good day.
Hi Dave. could you make a video about how you got started with Bonsai? what were your initial difficulties? how did you manage your space, tools, learning curve...?
Thanks Edinborogh, great idea. I wish I had more time to do more videos. I've got one coming soon about shallow pots then another one in the queue about a 9-tree forest planting. Then I need to do some early summer pruning.. and space is still an issue... hahaha I think I'm saying I have more difficulties now than I did initially!! I think I don't yet have enough subs to do a personal story, but it could work to show the challenges and setbacks, and how I overcame them. The biggest one is about tree deaths!
First!
Cannot deny it, you were quick to comment! :)
