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.20220530_191613.jpg
 
Nice amurs. Love the look and will be watching this for info!
 
Why do you want to prune the branches? These are in boxes, so I assume you are trunk thickening? If so, let those branches grow.

If you're happy with the trunks and want to develop branches you should be safe to prune back to the first 2 sets of leaves.
 
If you need space you could just buy this $1.25 roll of garden jute from the dollar tree (yes, only the tree one) that I still gotta get for these squashes and just tie the whole thing up, that'll expose the bottom to more light too.

Amur maple is totally OK with pruning so you can cut as much as you like and they will still grow new buds at any nodes and keep going.
 
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 prune, stabilize the trees and then limb prune in a couple months? Any input will be appreciated, I think I know the answer but my OCD is looking for confirmation. For what it's worth, the box pots are 11" square and 6" deep.

I think you can safely prune as much of the top down as you want during repotting. They both look fairly similar, I'd leave at least one of the alone to grow more while you start playing with the other. Good luck

Thanks for the response.
 
These are maples. You can take as much off the top as you like when repotting and they will still bounce back. They should also tolerate quite radical root reduction if required to get them into the smaller pots.
 
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.
 
How can one distinguish between amur and trident ?
Google pictures of both leaf types - it will be pretty obvious. Trident leaves are much smoother along the edges (actually, in general).
 
I think Amur has more pronounced veins too.
Compared side by side the 2 species are quite different but I'll need to get some leaves to check what are the key features.
 
Amur can die back significantly from large pruning sites, so keep that in mind. If you look at most mature amur maple bonsai you can see evidence of die back. The good thing is they backbud profusely below chop sites.
