hey eip3,i'm in buffalo , n.y. and the old timers always said to cut roots around jan. or feb.so as not to harm the tree. also if it is leafing out you might want to keep it sheltered inside the garage till after the last frost because if those leaves get frost damage you will most likely lose your brebra crop.

I can't keep mine any colder than the unheated garage. Some have Breba and no leaves yet. Others are leafing. The cold NW wind outside would kill them. Some of the Breba have already dropped.

The trials of the North East and fig growing.

I raised the very same question about indoor growth and this is the response I received. Just before I set my potted trees out, after the last frost date, I am going to prune as Al suggests.
