I picked up this big tooth maple (Acer grandidentatum) as a 1 gallon nursery tree a year and a half ago, at which time I chopped the primary trunk. I repotted in bonsai soil last spring and it grew very vigorously.
Am not familiar with the species. I think you’re right to try something to balance the vigor if you want to work with the lower branches. Thinning the upper branches could also do the trick.
Did a combo of reducing upper branches and defoliating what was left on them. The new leaves were much reduced and I think the lower branches will be stronger next spring, will update then. Thanks for the advice!
Looking good brad:+1: that’s a definite Improvement
