Troubleshooting
Viking black chokeberry problems — and how to fix them
Viking black chokeberry (Aronia melanocarpa 'Viking') 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.
Suckering spread
Viking spreads vigorously by root suckers and can colonise a wide area over time. Remove unwanted suckers at the base annually to maintain a tidy, controlled clump.
Leaf spots (Cercospora sp.)
Brown or purple leaf spots develop in humid conditions. Rarely serious; rake and remove fallen leaves in autumn to reduce inoculum. Fungicide treatment is seldom needed.
Birds eating the crop
Blackbirds and other birds target the ripe black berries. Net plants or harvest promptly when berries reach full black colour to protect yield.
