Expert Response

Thanks for your question. I suspect that your tree is showing symptoms of a disease described here: https://pnwhandbooks.org/plantdisease/host-disease/smoke-tree-cotinus-coggygria-verticillium-wilt

This is an incurable disease, and I suggest that you send plant samples to the OSU Plant Clinic for a lab diagnosis: https://bpp.oregonstate.edu/how-submit-plant-materials

Good luck!
