American Elm - drops leaves early
Tree: American Elm, est. age not less than 90 yrs. Treated for Dutch Elm every three years since 2007 via injection and "vitamin" injection three years ago. Looks healthy in spring and early summer. Later summer (Earl/mid August), leaves turn brown with dark spots and fall, slow at first but accelerates by end of month. I don't remember this happening up to two years ago. Photos taken 8/24).
