Here in the northeast, dogwoods are subject to "dogwood decline", aka
anthracnose, and this year it is particularly bad. Last year's severe
drought stressed the trees, and this year's cool, wet, extended spring has
allowed the disease to thrive. I have one dogwood that has been in decline
for some years, losing twigs and leaves and such, that is losing entire
branches this year. My "healthy" tree, that has resisted the problem so
far, is showing signs of it this year.

It's a crying shame; they are such beautiful native trees, with a form and
beauty unmatched by any other understory tree. But so it goes.....

Yes, I do live in the states. Zone 5. I did spray mine with a fungicide
because they had black spots and some leaves are turning purple and
dropping. Temps have been in the 80's to 90's. I thought mine was the
only tree until I started looking around. They all look like mine. My
main concern was the health of the tree. It's mature and I sure would
hate to lose it.
