My ash tree is losing leaves right now. I'm not sure what the issue is. Don't see any disease. I went to local landscape store with samples. She didn't see any indication of ash borer or disease and suggested I contact you.

Anthracnose, a fungal disease associated with wet weather and leaf
drop often affects ash trees at this time of year: Anthracnose of Ash
Trees

If you believe anthracnose isn't causing the leaf drop, ask a
forester or certified arborist to assess the tree's health and recommend
a course of action.
