Does anyone know if glazed pots present any advantage over unglazed pots or vice versa?

Given my root mass block of wood reference, until your response, I was a bit embarrassed to admit that in my frustration, I did break out a saw and cut the root mass block of wood in half, however I did not cut enough for tree to fit nicely in the pot. I now have four Chinese Elms to do. I...

Thanks for the responses. I will add the grated sphagnum moss. I pruned the root mass as much as I thought possibly could without killing the trees. As a novice, perhaps the veterans here have experienced this but on one of trees as I got closer to the base of tree the entangled roots were...

So I repotted two maples (one pic is attached) into bonsai pots and this is my first time ever doing so. My question is the soil medium level is convex to the top of the pot and while I've seen more than one like this on the boards, how the heck do you water the tree and not wash away the soil...

Thanks All!

Thanks for all of the information. This very helpful!

I have these JBP and I sprouted them last year and they need a lot more growing. But I am wondering, at some they'll need to be root pruned, correct? I've done some searching and found nothing definitive in this regard. If root pruned, when do you do it? I get it with deciduous trees...

I'll try that. I'll chop the Elms tomorrow and I will be doing the Maples Monday or Tuesday. Historically the Elms are a week to two weeks behind the Maples in terms of swelling buds. The Maples are presenting a little green at the swelling buds right now. Here in Maryland the winter hasn't...

Here is a picture of the referenced Chinese Elms.

Can a Chinese Elm tolerate a repot and trunk chop at the same time? I am guessing they are as hardy as an Amur Maple????

Thanks for the response (Shibui). I was concerned about just how much I could take off the top. Now planning to remove about half of the top and likely about 50% of the root mass.

Thanks for the response.

So this is a follow-up to my 2022 inquiry. I root pruned these two Maples 2 years ago and now I'd like to root prune them again and place them in a bonsai pot. My concern is they will be quite top heavy. To that end, can I do limited limb pruning at the time of root pruning? If not, just root...

Moved to correct OP.

Any response will be appreciated.... 5 or 6 months ago I sprouted these from seed and they seem to have grown okay so far. My question is unlike my Maples and Chinese Elms which I simply place them out of the wind they sit outside all winter. Should the JBPs be treated differently? Thanks

Thanks for your response. This was my second effort at root pruning as I did two Maples one year ago and very likely, as you point out, did not root prune as much as I could have. Each of the four elms had a root ball which averaged, probably, 10 inches in length and 7 to 8 inches width...

I am hoping someone can provide some direction. I root pruned (first root prune ever) four Chinese Elms today (03/04/2023) see the attached photo. Each tree is five years old this month, grown from seed and are 2.5 to 3 ft in height. I have two questions, can I prune back the limbs and the...

So I root pruned each of these trees Feb 28\Mar 1 and it seems I should prune the branches, however just how much will they tolerate, minimal or a lot? Any input will be appreciated....Thanks.

Are pots without drain holes useful, anyone know?

Just wondering....I have a couple of maple trees and they are budding actually approaching extended budding, Chinese Elms, almost nothing in terms of buds. Do the Elms generally bud later? Thanks.

I root pruned my first tree(s) ever, a couple of Amur maples. I realize there is no absolute time but any idea when it will be clear the root pruning is a failure and the tree(s) won't survive? Yes, I am more pessimistic than I probably should be.

Thanks for the continued input all.

So I can safely prune up to 75% of the roots? Frankly, my goal is to get the trees into smaller and shallower pots. Does it matter that this is the first pruning? Any thoughts will be appreciated.

It's nearly a year later and I'm hope to prune the roots in the next few weeks just prior to bud break, however it isn't clear to me how much root I can prune, 30%, 50%, etc., additionally can I also prune some of the limbs at the same time. I certainly have RTFM so to speak and I am still...

Hmm, we had many here in Maryland. I removed them when I saw them on my trees.......Thanks.
