Troubleshooting
Blanka Whitecurrant problems — and how to fix them
Blanka Whitecurrant (Ribes rubrum 'Blanka') 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.
Bird damage
Although paler than redcurrants, ripe whitecurrants are still taken by birds. Net or cage the bush from the point the berries soften until harvest is finished.
Currant blister aphid
Raised red or yellow blisters appear on the leaves in spring. The harm is largely cosmetic; control aphids early and accept minor leaf puckering.
Sawfly defoliation
Gooseberry sawfly larvae can quickly strip the leaves. Check plants from spring and remove the larvae by hand or treat before defoliation occurs.
Wrong pruning of fruiting wood
Whitecurrants fruit on older wood and spurs like redcurrants, so removing all old wood loses the crop. Maintain a permanent framework and shorten sideshoots rather than renewing fully.
