Ash tree spots
Hello I was just curious what these spots were and how I should treat the tree. I believe it is an ash tree. Thanks

Hello -
This is ash rust. It is a cosmetic disease that does not affect the health of the tree. Nothing to worry about and when the leaves fall - discard in the trash.
