Troubleshooting
Red Twig Dogwood 'Arctic Fire' problems — and how to fix them
Red Twig Dogwood 'Arctic Fire' (Cornus sericea 'Farrow') 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 stem color
Old stems lose their bright red and shading reduces intensity. Cut roughly a third of the oldest stems to the ground each late winter to renew vivid young growth, and grow in full sun.
Leaf spot and blight
Fungal spotting can appear in wet, crowded conditions. Improve air circulation, remove fallen debris, and thin congested stems to reduce humidity in the canopy.
Suckering spread
It spreads by underground runners and can colonise space over time. Remove unwanted suckers or install a root barrier if a contained footprint is needed.
Scale and aphids
Sap-sucking pests occasionally infest stems and leaves. Prune out heavy infestations and treat with horticultural oil; healthy, well-watered plants resist them better.
