I know it isn't some horrible thing, but i limbed up some trees. They were about 5-6 ft trees (oak) and I am getting little skinny limbs back on the trunk. Will they leave or do I need to remove in the near future? I wanted bare trunks up to about 3 or 4 ft up the trunk. I will just leave them on if they will eventually die out anyway. Why prune now and have to later.
