When to prune black redcurrant in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune black redcurrant
Cut out one-third of the oldest stems to ground level each year using loppers or a pruning saw. Also remove crossing, damaged, or inward-pointing shoots. Aim for an open goblet shape with 8–12 healthy stems of mixed ages.
Black Redcurrant 'Ben Lomond' fruits best on one- and two-year-old wood. Annual pruning removes old, spent stems to keep the bush open and productive. Remove roughly one-third of the oldest (darkest) stems at the base each winter, leaving a framework of young shoots to carry next season's crop.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
