Can I use wood putty to fill the trunk cavity of a maple tree?

Answer

I don't recommend regular wood putty as it shrinks as it dries. You are better off using foam that expands and covering it with a screen to prevent animals and birds from removing the foam. Also, don't use concrete to fill a hole. If the tree has to be cut down in the future, an unsuspecting person cutting down the tree could be injured.
