Is my pagoda dogwood diseased? #878713

Asked July 25, 2024, 11:12 AM EDT

Someone recently pointed out these formations on the bark of my pagoda dogwood. Is it a sign of disease? Despite the marks, the leaves higher up the limb seem to be doing just fine. There are no yellow bumps, so I don't think it's golden canker.

Thank you for writing.
I suspect but cannot confirm dogwood anthracnose, a fungal disease.

An ISA certified arborist should take a look. https://extension.umn.edu/planting-and-growing-guides/how-hire-tree-care-professional
