Troubleshooting
Physocarpus opulifolius 'Coppertina' problems — and how to fix them
Physocarpus opulifolius 'Coppertina' (Physocarpus opulifolius 'Mindia' (Coppertina)) 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.
Powdery mildew
The main weakness of ninebarks — white coating and puckered new shoots in humid, still air. Space plants for airflow, water at the base, and remove affected tips.
Muted colour in shade
Insufficient light dulls the copper-and-red display to green. Plant in full sun for the strongest tones.
Open, woody base
Older shrubs become leggy and bare low down. Renew by cutting the oldest third of stems to the ground in late winter.
Chlorosis on alkaline soil
Yellowing between leaf veins on very chalky ground. Improve soil with organic matter or, in severe cases, choose a more lime-tolerant shrub.
