old bark damage to maple tree
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?
As long as the tree is still healthy, you probably have nothing to worry about and may not need to do anything for it. However, this article may offer some suggestions to help you: https://www.gardeningknowhow.com/ornamental/trees/tgen/repairing-tree-bark-damage.htm
