Troubleshooting
red-twig dogwood problems — and how to fix them
red-twig dogwood (Cornus alba) 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.
Fading stem color on old wood
Only young stems (1–2 years old) display the vivid red color; older stems turn gray-brown. Cut back hard to near ground level every 2–3 years in late winter or early spring to stimulate a fresh flush of colorful young growth.
Dogwood blight (Discula destructiva)
Though far less susceptible than Cornus florida, cankers and leaf spots can occur in wet seasons. Prune out affected wood, improve air circulation, and avoid overhead irrigation. Hard annual pruning naturally removes infected wood.
Excessive suckering
Spreads vigorously by suckers and can outgrow small spaces. Dig out suckers regularly if a restrained clump is desired, or grow in a contained planting where spread is welcome for erosion control.

Most red-twig dogwood issues are care-mismatch, not bad luck. Dial in the basics:
