Tar Spot on Maple Tree
Question: Something is wrong with my Norway maple. Leaves have been falling off the tree for the past three to four weeks. The leaves still on the tree have very dark, almost black, spots with a yellow halo. What is wrong with the tree and is there anything I can do? J.M. and D.E.
Answer: The bad news is your maple has a fungal leaf disease called tar spot. The good news is your tree will recover with no ill effects.
