At least one of the mature trees in my yard has strange looking spots on it and I am concerned it is sick. It is a lovely tall tree, so I wanted to see if it can be treated. I'm attaching a photo of what the leaves look like. Is there anything I can do for it? Thank you!!
Charles, it is really hard to tell from this picture. Is it an oak tree? It could be jumping oak leaf gall, maybe. Can you google jumping oak leaf gall and see if thats what it is?
