Wild Plum Tree Disease
I have a wild plum tree that was producing fruit like crazy only a few weeks ago. Then, almost overnight it stopped producing. I noticed the leaves have very tiny brown dots all over them. Now almost all the leaves are covered with the spots, and I think the tree is close to death. What is this? What can I do? I used to think the tree was a nuisance, but now I really want to save it.
You might take some of the leaves to your local extension office to more clearly identify what you are dealing with. This sounds like a fungal infection of some sort, but they will be able to better tell you exactly what it is and the best methods to treat the problem.
