THANK YOU FOR SUBSCRIBING OUR CHANNEL!
Welcome to our channel! We are located in the beautiful Pacific Northwest (PNW)! We are in the middle of our journey to create a beautiful Japanese maple garden and develop bonsai trees for everyone to enjoy. Our garden is under construction but we hope to open it up to public in the near future! Follow us if you love Japanese maples and want to know what's happening in our garden! In this channel, we focus on walking thru our Japanese maple bonsai garden throughout all seasons, discussing how to prune Japanese maples, how to air layer Japanese maples, how to propagate Japanese maples and how to take care of them including pruning, fertilizing, etc.

I like this video , no talking just showing exactly what to do .
Oh love this shallow plastic pot!
Spring has sprung!! I enjoyed your garden tours and love seeing your maples coming to life. Thank you for sharing the first shallow potting of your tree. It’s good to see how much root work to do!
Thank you! Yes Spring is finally here and definitely exciting to them active again! :)
Very well explained. Thank you!!
Thanks for watching and so glad to hear it was helpful!
Well done. Thank you for sharing.
Thanks for watching!!
Great tutorial . Off to a great start. Thanks
Thanks!
Amazing
Great job!
Thank you! 🙂
thank you. great info
Good to know it was helpful!
Not enough Maple videos.......LOL.......just kidding. Great looking Maple. Looking forward to a video garden tour in spring, when all the leaves have sprouted out.
Haha never enough 😁 I expect the tree will have full leaves in a month :)
Very informative video! Enjoyed as always. Just one question. I’ve seen videos of this nature and most of them use cut paste on the larger cut roots is it not needed on maples?
good video :)
Thank you!
Can you elaborate on what is considered young & old/refined when it comes to bare rooting while repotting?
I would say a tree is refined when it's got good secondary and tertiary branches well developed with good nebari. At that point, we don't want to disturb too much under the trunk and keep the core (under the nebari) together and only remove the bottom & outer fine roots to regenerate more finer roots.
If I need to thicken the trunk, do you recommend bonsai soil like your using or a soil with less bonsai soil? Example: pine bark, potting/peat mix etc
The fastest way would be to use 100% pumice, let the tree enjoy the sun, fertilize well, and water many times a day :) if not possible (most likely), you can use any soil that drains well and fertilize properly then you can thicken the trunk pretty fast.

Lovely garden and nice video. You have the very big trees, and now the very small ones!
Love the tray not seen them in the uk
Yeah, this flat container is very useful for growing deciduous trees and encourage roots to grow more horizontally. Hope you can find something similar there!
I have two trident maples in nursery pots. Would like to move them to wooden planting boxes I made. Is it too late in the season. They have obviously leafed out, are very vigorous trees. I'd have to cut the bottom half of the soil mass like you show but would not do much else with the roots, just ad fresh soil to the box. Does this sound acceptable?
Hmmm I would wait till next year to be safe.
How old was this maple? Just wanted wondering at what point plant is ready or good enough to undergo this process. Thank you for this very informative video. 👍🏽👍🏽
Not sure but I would guess probably 7 years in the container. You can do this to any nursery stock to clean the tangles roots and give it a fresh start as a bonsai.
Great educational video. Just what I needed. Which brought me into a question. I recently got a few 1-gallon JMs. They're very young ( probably half size of the tree in this video), and I was wondering when would be ideal to take them out of the nursery container and repot them in a shallow pot?
Also here in NY, we get strong wind year-round, I was wondering how well JPs do in the wind. If that's a big NO, I gotta rethink about the spot where I keep them. Thanks in advance.
You can start early but the focus should be to fertilize with high nitrogen to let the trunk thicken fast :)
As long as the roots are well established, they can take some winds but not young ones and recently repotted trees.
@@MomijiEn Thanks very much. Very helpful. Appreciate it.
I am in San Jose, California. Is it possible to repot small (2-3ft tall) Japanese maples in the summer (today, July16 - end of Aug)? I do not want to cut/remove any roots, just change soil and to bigger pots. Thank you.
Nice! I used to live in San Jose CA for almost 15 yrs before moving to Washington just 4 years ago! You can slip pot it (and add new soil around it in a larger pot) without disturbing the roots.
Hello,
Great video thanks!
I'm interested in the container I saw in this video. Where can I find it.?
Thank you very much! It's called Anderson Flats. I used 17 x 17 x 4 for this video. I get a bunch locally. I am sure you can buy them online.
Thanks for the feedback.!
I have a couple maples that are holding a lot of water because of the rainfall this winter. I live in Atlanta Georgia where the winters aren’t that cold. Would you repot the trees this early into some bonsai soil and keep them in an unheated greenhouse? I know we usually wait till spring to repot.
We have the same issue in the PNW as it's continually wet throughout the winter here. As long as the soil drains well, you can leave them outside as long as the temperature is not too low, or you can move them to a greenhouse or garage. You can technically slip-pot anytime you want as along as you don't mess with the roots.
The trees recover pretty good when you repot them like that? Since your removing the original potting soil.
@@Deshojo78 yes they grow a lot faster with better soil that provides good drainage.
as always, silwnt peacfull vid, but that fast forward made me dizzy 😅 I suggest cutting segments of the vid to shorten out parts
Hoping you can help me. I have two JMs that are in large pots and in the Midwest during our snow storm I was able to move all my JMs in the garage except those two. They have buds but no leaves. Out of 30 they are the only two with no leaves. The buds dont look as plump as normal and I think they are damaged. The rest of the tree looks fine. They are Waterfall and Inaba Shadire. Any advice?
As long as those little buds are reddish color and alive, they will eventually leaf out!
@@MomijiEn thanks! Hope so
Where do you buy your plastic bonsai container/?thanks
It's called Anderson flat. You can also use pond basket.
Hello! I was just wondering where you get your nursey stock, is it just a big box store or a bonsai specialty store? Thanks!
Roughly 60% from local nurseries, 20% from bonsai nurseries, and 20% propagation in the garden :)
What water nozzle do you use? Like the tight shower pattern.
Nothing special - I think I got this from Home Depot - its called something like Flexzilla Heavy-Duty 7-Pattern Adjustable Pistol Grip Garden Hose Nozzle :)
@@MomijiEn must no longer be in production. Found a 6-pattern one but the images does not show what yours does. Thank you for replying to my inquiry :)
What fertilizer do you use for maple?
I use Osmocote Plus for young trees & organic fertilizer like Bio Gold for more matures trees.
This was great! May i ask, was it spring bud swell time when you did this? Is that when you did? Can i do it in winter or do i have to wait for bud swell>
Hi Lisa, yes I did this when new buds are about to or starting to swell/open. The reasons are 1) the tree can quickly recover from all root/brunch pruning as it's going to be active immediately 2) it's a good time to do it without worrying too much about water bleeding 3) we want some nutrition from the roots to move over to push new buds, if you cut them too early in the winter, you are also cutting off all roots with stored nutrition from the previous year. Hope this helps!
@@MomijiEn good info. my three trees in pots aren't bonsai, but still 3-4 ft tall. i want to repot them from 7 gallon pots to shallow pots, but NOT bonsai size. just shallower pots for my patio to live for a long time in. since they're nearly bursting out of their existing pots, what would happen if try to follow your instructions in say, the fall? ours don't really drop leaves here until around November! if i tried in October would it hurt the plant over winter? we hardly ever get close to freezing around here even in winter... what do you suggest? what about during dormancy?
@@MomijiEn sorry i know that was a lot of questons, but they're too big in their pots to wait til spring for repotting so i'm trying to plan?
@@lisademayo8589 no problem, happy to help if I can. you can simply "slip pot" it, meaning you can pull it out from the current container, move it to a bigger container with more soil around it without disturbing the roots. This will help the tree have more space to grow in the meantime and you can do the root work early next year.
@@MomijiEn oh hey i was just thinking as you were responding and you happened to just bring it up!..... i was thinking, can i still cut HALF the bottom of the soil ball and slip pot it into a shallower pot? in other words, do the slip-potting as you JUST suggested but put it into the shallower pot as is? i THINK that would be okay based on what you just replied, and then wait til spring to do all the little parts in your video? is that okay? cut the bottom off and slip pot it?
It survived, right?
Yep, it's doing well
Hi can I do it in the fall? Thanks
No, I recommend you wait till late winter / early spring :)
Well, now I’m confused…..
Where do you get the square pot you used for the planting?
I got it from a local shop. You can find it online by googling "anderson flats" container.
@@MomijiEn thanks
@@MomijiEn how long do you leave it in these flats to let the roots grow before repotting to the final bonsai pot?
Tidak memakai tanah?
Wouldn't cutting the roots cause a shock? How do you do that without killing the plant?
You only want to do root work in late winter or super early spring right before or right when new buds start moving.
@@MomijiEn Do you cut only the smaller roots?
@@freshface2991 you can cut major roots during the specific time with minimum impact to the tree.
Where can i buy a black tray with holes like that
What I am using is called "Anderson Flats" container which you can buy in the US. You can also look for pond baskets which work the same way.
Nice work, please use a tripod as the video is too jittery.
Yes I'm getting a gimbal so that should help 😁
that dont look like soil, just pebbles and rocks, is that enough, wont it starve
50% pumice and 50% Akadama. Good soil mix for Japanese maple in the PNW where I live. 🙂
Sorry for the feedback but I hope it helps. I would have loved to watch this video but all the jerky movements of the camera really hurts my eyes. Better not to have a camera fixed to your body.
Thanks for ur feedback!
