I undertook some drastic pruning of this Amur maple last year and at the weekend noticed buds starting to swell so it was time to root prune and repot.
I was a bit disappointed to find one thick root that dominated the pretty much one sided nebari. I expected better because this was originally a cutting from a parent tree. In hindsight, I should have checked the roots last year.
However, there were still other roots present that helped me determine the front of the tree last year when pruning. Aside from the thick root, I was really pleased with the rest of the rootball which was quite flat and even. It was like cutting a cake. I removed a substantial amount on the side with the thick root and also pruned that back too. I had a spare shallow cream pot available and so placed the tree in that. It should make a nice image when more branching and foliage is developed this year. I tilted the tree towards the front and some fine roots were exposed once potting was complete so some moss was placed on part of the surface to prevent them drying out.
