Hello,

I normally frequent the trees and conifers forum, but have recently become interested in bonsai. I have a striped bark maple (A. pensylvanicum) that I have been training over the past two years. Its trunk has thickened and it is developing a nice network of smaller branches in the crown. However, the plant has not been re-potted since I collected it two years ago. It is currently growing in a very large (1.5' wide by 8" deep) pot. I am wondering when would be the best time to re-pot it into a bonsai pot. As this would require a great deal of root pruning, I was wondering if there was any specific time of year that would be best for the tree as far as its ability to cope with the shock of re-potting.

If anybody wishes to see pics of it, let me know.

Thanks for helping a newbie!
