Asked June 7, 2017, 10:34 PM EDT

Can you give me an idea what's wrong with my sugar maple and will it survive or is here something I can do. Wondering if it's just a fungus from he wet Spring? See picture below. Thanks

Yes the damage probably is the result of a fungus called anthracnose that affects the leaves of maples and many other trees in spring. Damp, cool weather favors its development.
