Tar Spot

Tar Spot



What is it?

Tar Spot is a fungal infection that affects Maple trees. It's found to not cause any real damage to the tree, other than making it an eye-sore.

What does it do?

This fungus, like many others, overwinters on leaves from the previous year. The dead leaves on the ground release spores in the spring of the next year. These spores reinfect the maple tree or other maples nearby.


Do you have it?

This one's pretty easy to diagnose. Look at the leaves from your maple. Do they look like someone splashed tar on them? Like the pictures above? If so, you have tar spot.

How to manage it:

Since tar spot is not a damaging fungus, most cases are just ignored as they will nomally subside on their own. If it is something you cannot stand to look at, then you can call your local tree service company to see how much a fungicidal treatment would cost. The fungicides are the only thing proven to take care of tar spot. But make sure you call in the early spring because this is when the fungicides will be most effective.
