Maple disease
Most, if not all, of the maple tree in our area seem to be diseased. The leaves are turning black, drying up, falling off, and turning to dust. The end result looks like someone burned the leaves. Any idea what is wrong with them and how to fix them?

Most common affliction of maples at this time of year is anthracnose, a fungal disease. Could also be infected with maple leaf blister at the same time. All is made worse by wet weather, which much of Michigan has had plenty of this spring. There is no available treatment and as ugly as it can be, long term health of the tree is usually not affected.

As explained, leaf samples can be sent to Diagnostic Services for a correct
diagnosis.
