If it was just a few of the branches I would say to prune them out and reduce watering (I know - it's been so rainy...) and maybe it would limp along. But if most of your tree is afected, it's probably not going to survive :-(

This has been an awfully rainy summer, and Cotinus requires very well drained soil if it is going to have a chance of avoiding V. wilt.

Sorry!! It is such a nice tree that it is a shame to lose it!
