The leaves on three of my maple trees have a black substance on them that I can brush off. It is on everything under the trees also. They have lost large branches in the past. I have other maples without this issue. Are my trees in trouble?
It sounds like you have a substance called Sooty Mold which is a fungus that grows from the "honeydew" waste of insects such as scale or aphids. We would be happy to get a look at the trees to give you a true diagnosis. Please, contact our office if you would like to schedule an appointment.
