Any help appreciated. We have a couple of trees in our front yard in Hunt Meadow in Annapolis that are struggling. Here are a couple of photos of two silver maple trees (I think) with issues which have shown up this spring. The trees are about 25 years old and 30' tall. One is a diminished number of leaves this year and the other has all leaves but some black spots on leaves. They are in the front yard next to each other.
