I have a maple tree that is about 15 years old. The bark near the bottom was lost several years ago. The area is an oval about 1 foot high by about 8 inches across at the widest point. It reaches about 1/4 the way around the trunk. The tree appears healthy but I was wondering if there is something I should do to the tree or if it's too late?
