I would say that they are all semi-dwarf. The new one that was planted, i'm not sure. I would definitely cut them off if I hadn't taken so much wood already from the trees. If I was to prune again next spring, I would take them off! They were all destroyed by the deer and lawn mower anyways! The guy who owns them has some small grandchildren. I thought it would be fun to leave some of the lower ones for them too!
