Brilliantissima red chokeberry problems — and how to fix them
Brilliantissima red chokeberry (Aronia arbutifolia 'Brilliantissima') 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 in warm, humid conditions with poor air circulation. Prune to open up the canopy, avoid overhead irrigation, and apply a sulphur-based or neem-oil spray if severe.
Legginess in shade
Plants in low light develop sparse, elongated stems and poor autumn colour. Rejuvenate by hard pruning to 15–20 cm in late winter; new growth will be denser.
Bird predation on berries
Berries are relished by birds which may strip the display early. Plant in groups and accept some wildlife sharing, or use netting over individual plants if berry persistence is a priority.
