All as we have come to expect from your videos: clear, concise, well-thought out and delivered.....and accurate. Thanks again for the hard work you do on all our behalf. There is science intertwined with the art after all.
Higher N after leaf set in Spring. Balanced NPK during summer, easing off in mid summer as they enter semi dormancy. Then a boost of P,K biased fertiliser in Autumn to help the plant strengthen it’s cell walls for the winter! Anything more complex and my head hurts!
Thank you so much! Every once in a while I wonder whether I am overlooking something fundamental. The basics of bonsai are often made complex. Where they should not be. Stop overthinking.
I am relieved to have watched this video. I have known to use certain fertilizer to correct problems but only because labels will say "bud booster" or "leaf out" and the like. Understanding this more completely changes the game for me and may have saved a few plants in my collection. thank you very much sir!
@@GrowingBonsai I'll definitely be here for it! I'm not worried about it being boring, haven't seen one of those yet from you. Enjoy the rest of the weekend.
That is a great summary. I have been talking about the same things when it comes to plants in ponds. Adding nitrogen to reduce phosphate buildup resulted in less flowering. I agree that it does not matter that much in bonsai. Our trees take what they need from what is awailable and the rest is flushed out via the drainage holes. Some over intake are always happening if one nutrient is abundant. liebig's barrel is an easy way to explain it.
Absolutely phenomenal explanation and breakdown of fertilizer and it's effect on the trees. I'm going to have to watch again and take notes to look back on in the future!
One of the better Bonsai fertilizer videos. Your breakdown was direct, simple, and very much on point. New and old bonsai enthusiasts should have a better understanding on not just the brand or usages of it, but a better understanding of what the fertilizer they are considering or currently using. In the end you get a healthier Bonsai. Looking forward to the subsequent fertilizer video you mention. Also, like the graphics/drawings you utilized.
Hi Jelle, dont apologize for the lecture informative videos like this are a welcomed addition to bonsai channel. I follow you for quite some time and wanted to share my apprieciation :) Keep up the good work. Would love to hear/watch sth on the topic of yamadorii, do you collect trees from nature from time to time?
Great to hear. I do sometimes collect trees (But from gardens). I have 2 in the making, one on Elms and one on Taxus. There is a short video on pulling a juniper from a garden out. The Elm and Taxus will not come out until 2024, as I prefer to also show successful outcomes and not just the work done.
@@GrowingBonsai I have one kind of unrelated question that I wanted to get your opinion on. Do you mist your trees? Some say it helps with increasing the humidity others that humidity doesn't really change and keeping leaves wet fot to long is asking for fungal/other infections. Any thoughts?
@@BartoszBassa in summer when it is hot i hose the trees down. But normally I try to keep things dry. Keep in mind, normal years I have over 200 raindays..
Great video and well explained. I have ended just sticking to a balanced granular fertilser that I can mix in with the soil at repot or sprinkle over the top. It is from Oceana and relatively new on the market but a lot cheaper than the Biogold regimes. Thanks for this.
@@GrowingBonsai No - but I think you showed that in your won way. It was informative and I definitely learnt stuff. Brown spot on leaves is a constant issue with my satsuki. Drives me nuts!
Excellent video Jelle. When it comes to Bonsai fertiliser, I never know which way to turn and for the most part try to make my own. But this video really helped. Thanks for the info.
Zeer duidelijke uitleg. Ben blij dit te horen. Ik combineer koemest korrels met chemisch 15 - 10 -10. Zeer goed resultaat. Ik doe dat omdat men zei dat dat een goede combi was. Maar nu begrijp ik ook waarom. 👍👍👍
Great information! I was not using fertilizer for a long time, I still forget to fertilize. I give my plants water from the aquariums regularly and have well water. I try to remember to fertilize, I just have 20-20-20... I really do not have a strong understanding of fertilizer other than, it's expensive Haha!
It does not have to be. Some of my fertilizer comes in Big Bags that are really affordable. Just do not buy japanese organic pellets because there you pay a lot of money for ..
@Growing Bonsai by Jelle I bought miracle grow powder. Like Nigel uses. I got it from Walmart for about $35. I use it sparingly as the price has gone up since i purchased it. I can get fertilizer sticks from the dollar stores for about $5 a package, they are garbage hahaha. Pretty much everything from the garden centers is more than I can afford. There was nothing in any garden centers under $60, even the same fertilizer i got from Walmart was double the price there. I will have to save up and order off the internet maybe. I'll get it figured out. My trees seem to do just fine without all that stuff. I'm still using soils with organics in it as I'm not home all day to water. They dry out really fast inside the house.
Hello Prof. Dr. Dr. Jelle, can we please discuss the redox reaction 6 H2O + 6 CO2 = 6 O2 + C6H12O6 in your next lecture. As an automotive engineer, we only had hydrocarbon chains without oxygen atoms, even if sugar is energy, we always want to burn something that doesn't make us fat. Respectfully and with great anticipation for the next lecture, your student Patrick!
Hi I have been looking at your other videos Love the practical advice you share I am amazed at the fantastic growth you get in your maples and figs over one summer , I only get growth of about 2 inches if that , how can I get my trees to be 5 times as big by the end of summer thanks
I think it is the combination of the water/oxygen/fertilizer triangle and the right position for the tree. My trees never dry out to wilting point, and are fertilized throughout the growing season. The substrate is very coarse so in summer there are days that I have to switch on a mister if I am away from home for the day, to ensure midday-water.
i go into this kind of depth when it comes to asexual reproduction... studied it extensively... i love how in depth you go into this fertiliser video. i find you very interesting mate :) and will look into it :)
@@GrowingBonsai Are you from the Netherlands? (That is what I tought because of your accent and name) Lodder bonsai will have an open day. Peter Chan and Jan culek will also be there.

Wow, thank you! I am getting a little embarrassed here!
Very well explained! Thank you for your all this great information. Love the consistency of your Uploads 👍🏼✨
You're so welcome! I might have to drop the frequency as my topics might run out!

You are very welcome! If you are part of any social media groups on bonsai, feel free to share this around :)
The "lecture" was great! Looking forward to the next in the fertilizer series.🍻
OK, so now I have to make it right? I was just looking at my recordings for that one.. And it is soooo boring!
@@GrowingBonsai I'll definitely be here for it! I'm not worried about it being boring, haven't seen one of those yet from you. Enjoy the rest of the weekend.
Thank you Professor Jelle 😁. Very informative and crucial video. Steve👍
Hahaha, well, professor is a protected title here, so lets stick with Dr :)
Hi Jelle, not boring at all. Keep up the lectures! Thanks
Thank you!
Really enjoyed the academics behind this
Very helpful hints from a professional guy. Thank you for this theoretical lesson.
Thank you for the compliments Andrea!

Another superb video Jelle. Lots of in depth knowledge clearly delivered. 👍
Ohw thank you so much! A lot of thinking went on before I made this. Only the delivery of the topic was a challenge!
This was super helpful and well explained - Many thanks🙏👍
You are very welcome! Glad it was usefull!
I like the lecture. I took a lot of notes. Thank you.
Glad it was helpful! :)
Academic lectures are fine by me sir. I'm here to learn. Thank you!
Excellent! I might just make part 2 equally dry :)
Great informative video. Thanks, Jelle!

Thank you so much! SO happy you enjoyed that!
Love the info, it’s always to the point. My only question is, what was the cereal box in the background on the tree for?
😂 You mean the tomatoe fertilizer? Just to keep people entertained :) Fertilizer does not really grow on trees

@@XaviersBonsaiRetreat is brown spot nor more fungal than fertilizer?

Very interesting Jelle but what about when to add fertiliser and when not to ? Or what happens if we don't feed at all ? Keep growing.xx
:) such a BIG domain!

Wederom een heerlijke video☺️
Fijn te horen!

enjoy
More lectures!
OK, be carefull what you wish for. I will try to minimize the dose of boring lectures though!
Hi Jelle, are you going to the bonsai open house march 11?
I do not know which open house that would be :)
@@GrowingBonsai Are you from the Netherlands? (That is what I tought because of your accent and name) Lodder bonsai will have an open day. Peter Chan and Jan culek will also be there.
Hi, is Bonsai focus a good liquid fertiliser?
I have no idea. I do not know the product
Have ever m done air layering from Bougainville?
Do you think it’s possible. Last year I wasn’t successful with Acer palmatum. I’m a little bit cautious. Would try this year again
I have not. I have taken cuttings though. So yeah, I think it should be possible.
Do you know what went wrong with the maple layering?
@@GrowingBonsai and the cuttings were successful? When did you took the cuttings?
@@GrowingBonsai it was a red Acer. I don’t know if it’s working with red once. On TH-cam you find air layering only with green Acer
Awesome, I think you have a scientific background, don't you?
I think so too. www.researchgate.net/profile/Jelle-Ferwerda
What NPK ratios to use?
exactly!
@ i dont get it
Alreadt summer at your place?
*sent with jelousy from south germany*
:) I tape these videos whenever I work trees and store them. I have about 25 videos in the making with scenes throughout the year :)
decent primer mate
Thank you so much!
👍👌🙂
