red twig dogwood leaf spot
I have a red twig dogwood that has spots on its leaves. There is some leaf drop & leaves turning red (even though it's summer). We have had an unusually wet spring & summer here in humid VA. Is it septoria leaf spot, anthracnose, other? Can I leave it be or do I need to treat it to help it survive? Will it spread to a nearby flowering dogwood tree?
