I have a young Japanese Red Maple I purchased about 24 months ago at Lowes. It appears to have what looks like small white/tan spots scattered on the leaves. Otherwise, it looks healthy. I have not been able to discover just what this is and if it needs treatment.
These spots that are on the leaves are more than likely a type of leafspot fungus. This year, we have had quite a bit of cool rainy weather, which leafspot disease thrives in. Depending on the severity of the disease, it may or may not need treatment. Set up an appointment to have it evaluated by an arborist.
