Maple - Brown leaves #873201
Asked June 15, 2024, 9:21 AM EDT
The leaves on our maple tree are showing some distress - brown spots in varying sizes that grow to destroy the leaves. It is watered M, W, F. The tree trunk is 10" - it's a fairly young tree. Additionally, there are black spots on the leaves - might be fly poop, but I wanted to check to make sure that's not a problem. Thank you!
