Ben Sarek Blackcurrant problems — and how to fix them
Ben Sarek Blackcurrant (Ribes nigrum 'Ben Sarek') 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.
Branches splaying under crop
Its heavy yield on a compact frame bends and breaks stems. Fit a circular plant support or stake early in the season before berries weigh the bush down.
Big bud mite and reversion virus
Mites swell buds and can transmit reversion virus, which has no cure. Remove enlarged buds in winter, use certified stock, and replace infected bushes.
American gooseberry mildew
Powdery white growth on shoots and fruit; the cultivar has good resistance but congested compact growth can trap moisture. Prune to open the centre and avoid lush nitrogen growth.
Birds taking fruit
Ripe currants are quickly stripped. Net the bush or use a fruit cage as berries colour, especially easy given its small size.
