What are black spots on maple leaves?

Question

Many maple leaves have black spots that grow up to 3cm in diameter. What are they?

Answer 1

It's a disease called tar spot. It doesn't hurt the tree because the leaves fall off before it has a chance. When the leaves are gone, so is the disease. You don't have to treat it but it helps to dispose of the leaves in the landfill with your trash so the tree does not get contaminated again next year.

Answer 2

Are the spots spreading or are they staying positioned? it somewhat is a fungus or something could have been sprayed on the plant it somewhat is inflicting the spots. If the spots are actually not getting any worse and not spreading, something could have been sprayed on the trees (possibly something develop into sprayed interior of reach and drifted onto your trees). possibly something dripped or fell on the leaves... how tall is the tree? It sounds like it ought to be an abiotic difficulty (non-living, like something develop into sprayed, something that's no longer a fungus) as a results of fact the leaves are nevertheless eco-friendly and not falling off. assemble a pair of leaves. If the spots somewhat rub off, then this is no longer a fungus. If the spots proceed to be when you rub them, it somewhat is a fungus. If the spots are turning out to be worse, take a pattern on your community illness health facility. they could check out it for you and enable you to already know what form of fungus, despite if it somewhat is a fungus, you have. in addition they are going to have the skill to propose a perfect scientific care or administration approach for you.
