Troubleshooting
Dog Rose problems — and how to fix them
Dog Rose (Rosa canina) 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.
Blackspot
Black or brown leaf spots, especially in wet summers; less damaging to this tough species than to cultivated roses, but clear fallen leaves to reduce reinfection and improve airflow.
Rose rust
Orange powdery pustules on the undersides of leaves appear in damp conditions; remove affected foliage and avoid overhead irrigation. Usually shrugged off by vigorous established plants.
Overly vigorous spread via suckers
Arching canes tip-root and suckers colonise surrounding ground. Prune out unwanted growth after fruiting and remove suckers at their base to keep it contained.
