I just put the black tube on last fall because the deer decided this was a good tree to remove their velvet on. This tree and almost all my other fruit trees are all suckering. I have white tree guards(tubes, but not real tree tubes) on some, nothing on others. I just use the white tree guards to protect from rodents(mice, voles and rabbits) and they have worked fantastic for 6-7 years. I also have cages on most of my trees until they get as large as this one. I don't care if the deer browse the tree(to a point), but I don't want them rubbing on them.
I removed the black tube last night and trimmed all the suckers on this tree. Fleet farm did not have the "sucker punch" in stock last night, but I will find some and give that a try.
