Late summer repotting

[BobbyLane]

i did this taxus about 3 or more weeks ago, no before pics because the tree is nothing special.it was in a deep nursery pot.after i saw G potters new video i thought id repot it and so far it seems fine, i think ill be able to sell it soon after some work on the top jins.i repot in spring too, im really not that fussy.i have hornbeams thriving that were repotted during dec or jan.

They are doing just fine.

not ,much of a surprise. People have been repotting in summer forever. Somehow it feels like you think you found something new?

I did this to a juniper this summer....does HBR count?

HBR Job on my Big Juniper

.....well its big to me, relative to my tree collection. This my first time attempting to Half-Bare-Root a tree. I think I lucked out with the last one, fully bare rooted with a hose....all is well with it, but I don't wanna take those risks anymore. I think I got into it as well as I could...

Oh yes, indeed
But it is not @Rafael Najmanovich's personal problem.
Many experts around here still know it cannot be done.

No. We are talking repotting. Not bare rooting. Let alone half bare rooting.

The proof is in the pudding, ~spring pudding. It doesn't matter what they look like now or into fall, how they wake up and do next spring, that's when a judgment can be made.

I make judgements when I see roots.

It's getting kinda bloody cold.

during summer dormancy

If you are so lucky to have summer dormancy.
I don't get that option.
My trees grow from spring until fall nonstop.

You know just how to make lots of new friends!

You don't generally see roots developing while the tree is dormant. I have been telling you guys that our concepts as to when is a good time to work on a tree does not necessarily mean when the tree is dormant. Personally evidence seems to indicate our ideas about all of this is a pile of doodie, I believe the best time is when the tree is actively growing. I repotted a bunch of trees this summer and all are doing well.

Yeah, I wasn't advocating dormant work.

It's just getting a little bloody cold to repot.

That was in response to .....

Here, waking up in spring doesn't really mean anything.

If I see roots in fall, I know the top is doing it's job still, and it's a more reliable sign of health, real health.

So, I see that today the official high in Berwin was 70F and the low is going to be 64F and that the forecast for the next week is for temperatures like the height of my summer. Wadda ya mean 'bloody cold'?

 

[sorce]

Wadda ya mean 'bloody cold'?

high in Berwin was 70F and the low is going to be 64F

However cold that I can't/won't repot anymore I guess.

Dewy, always wet, almost don't have to water anymore except for junipers.....

These are the same conditions that make spring repotting a no-go for me.

It smells of fall and cold.

Plus, next full moon ain't for 2 weeks and that puts me way too far.

Late summer repot...... bring it angry people! We do it in Korea too.

Anyone else in the last three or four weeks that passed since this thread started did any repot of a deciduous broadleaf tree? Even more so, did any of the vocal nay-sayers here if they are based in locations that allow for a late summer repot tried to expand their mind based on facts and their own experimentation? I hope so but I doubt.

I repotted a hybrid Korean maple x Japanese maple from its nursery container into a colander. I barerooted and did extensive root work when I repotted. At the same time, I also separated the air layer that I had started in the spring. Separation of the air layer was premature. There were not as many roots on the layer as I had anticipated. So, the air layer is probably not going to make it. The main tree, however, is doing just fine since the repot.

I repotted three of my average looking deciduous trees about two weeks ago: a hornbeam (carpinus betulus), hawthorn and field elm. Hornbeam: i didn't touch the roots, field elm: i cut about 50% of fibrous roots. A Hawthorn (20 - 30 years old yamadori) had been ground growing for about one and a half year on my garden. When i dug it up i was shocked: there were only three tiny roots alive. I didn't want to just throw it away so i repotted it in a very big training pot with perlite + some beaked loam and pine bark. After 14 or 15 days leaves on my repotted trees are still green, so i can say so far so good

I am a bit worried about winter, because i don't have a green house (i own some kind of unheated room which doesn't offer optimal conditions to my trees), that's why i repotted these 3 trees in bigger training pots, they have beter chance surviving the winter in bigger pots imo.

Actually yes; been photographing them each week since, and will share the results when they are conclusive.

Hijack:

I picked up this pre bonsai dwarf Acer palmatum (maybe an Akita Yatsubusa?) early this spring from my local bonsai nursery. There’s 2 new chutes that have popped up, assumingly from the same root system. This is a nice little bonus surprise.

I was planning to propagate these new growths next spring, but all of this ‘late summer repotting’ talk has me thinking of separating them now.

I don’t plan to reduce any roots, it is not pot bound. I plant to disturb as little as possible to repot the new growths.

What do you say, do it now or wait until the spring?

I would leave it if I were you. 'Late summer repotting' has parameters. Does the tree need it? Are the shoots stable enough to not only survive but thrive? In bonsai you want the tree to thrive not just survive. In my personal opinion leaving them to store up sugars and energy and repotting in spring would be better.
Besides on the lunar calendar Autumn has started so in most places it is too late........ a month ago would have been fine but now you are pushing it.

Ya, I agree. I guess they’ve just been calling out to me so I was looking for an excuse.

They don’t have much growth, so they likely rely on the primary plant for photosynthates.

Thanks for the dose of reality.
