Maple - Verticillum wilt?

Asked August 28, 2017, 2:03 PM EDT

I have a maple tree, estimating it is 30+ years old. A large branch has lost leaves and generally the tree does seem to be in trouble. From research and a phone call with a local tree person, it may be Verticillum wilt. How can I be sure? I would like to confirm the issue before determining next steps. Deborah

I suggest you contact a certified arborist to inspect your tree if you want a diagnosis:

The symptoms you described are consistent with verticillium wilt, but it could be something else. Verticillium is difficult to diagnose for certain without lab tests. Check this diagnostic site:

Verticillium may or may not be serious, depending on a number of factors. Read here:
