Cherokee Chief Dogwood problems — and how to fix them
Cherokee Chief Dogwood (Cornus florida 'Cherokee Chief') 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.
Dogwood anthracnose
Discula destructiva causes tan leaf blotches with purple margins, twig dieback, and trunk cankers; worst in cool, wet, shaded conditions — improve canopy air flow, avoid overhead irrigation, remove infected wood promptly, and consider protective fungicide applications in spring.
Powdery mildew
White to grayish powdery coating on leaves in warm, humid weather reduces photosynthesis and weakens the tree; site in good air circulation, avoid water stress, and apply horticultural oil or sulphur-based sprays if severe.
Dogwood borer
Larvae of Synanthedon scitula tunnel beneath the bark, typically entering through mower wounds; keep a clear mulch ring around the trunk, avoid any mechanical damage, and maintain tree vigor through regular watering.
