Physocarpus opulifolius 'Center Glow' problems — and how to fix them
Physocarpus opulifolius 'Center Glow' (Physocarpus opulifolius 'Center Glow') 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
White powdery coating on leaves, worst in shade or with poor airflow and high humidity. Improve spacing and sun, avoid overhead watering, and prune to open the canopy.
Faded foliage colour
Burgundy tones turn muddy green in too little light; relocate to full sun to restore the rich colour and the bright central glow.
Leggy, open growth
Sparse, woody framework over time; renew by removing up to a third of the oldest stems at the base after flowering to encourage dense new shoots.
Aphids
Clusters on soft new growth causing distortion and sticky honeydew; dislodge with a water jet or treat with insecticidal soap, and encourage ladybirds.
