Sick Maple Tree
Your maple tree leaves are infected with a common fungal disease known as tar spot. While the black spots look serious and leaves prematurely fall from the tree, rest assured that this disease does not impact the overall tree health. Consequently, no pesticide applications are recommended. Raking and destroying the leaves in fall is the most effective management technique.
