Hi! I have 2 maple trees with similar bark problems: ~15 yr old autumn blaze maple - bark is stripping off and underneath the bark on the trunk about a foot from the base are bored holes about the diameter of a pencil
~45 yr old silver maple - bark is stripping off (but no bore holes)
I'm concerned about the barking stripping off. What causes it and how can I address it to save the trees? Thank you!
