On the subject of late fall defoliation; is this done for aesthetics mainly or to make for a more tidy and disease free environment when putting trees in winter quarters? All my trees are bare now except for a few on my large JM and my Southern sugar maple (btw excellent fall color on this one up here) and I figure I will let the leaves fall off or freeze off then keep especially the sugar maple in conditions suitable for zone 7 bonsai.
I've only been doing bonsai a little under 2 years, so I don't have much experience with late fall defoliation, but I gave it a shot this year for the reasons you mentioned and because I wanted to wire a couple of them before it got wicked cold.
I have two elms and a kiyohime that are still super green, so I'm giving them a little more time.
