I have a 16 yr old maple tree. I have noticed that some of the branches are dead. The rest of the tree seems healthy. What could have caused this? . I am worried that the rest of the tree will go the same way. I would appreciate your advice. Thank you.
Another possibility is too much shade from bigger trees that have grown out. Not much you can do about any of thes, except perhaps the shading. Do not feed, but water well during a dry spell.
