Troubleshooting
Cotinus obovatus problems — and how to fix them
Cotinus obovatus (Cotinus obovatus) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Dull autumn colour
Usually too much shade or over-fertile, moist soil. Plant in full sun on lean ground for the trademark fiery display.
Verticillium wilt
Like other smoke trees it can suffer this soil fungus, causing sudden limb dieback. Prune out dead wood and avoid replanting on affected soil.
Root rot in wet soil
A dry-land native, it declines on heavy, soggy ground. Ensure sharp drainage and never overwater established plants.
Slow establishment
It can be slow to settle and resents root disturbance. Plant young, container-grown stock and avoid moving it once sited.
