I planted 3 dwarf apple trees 2years ago and thought this would be my first year getting fruit. I went out today and looks like about 2 1/2 or 3 feet up something has ate the bark half way around the tree. I am afraid i will lose the tree. is there anything i can do to it to help heal it's wound? I live in a small town and i think deer may have got to it, I am at the edge of town. I hope whatever it is don't bother the other 2 trees. Can you help me!!!
