When to prune buffalo currant 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 buffalo currant
Cut one-quarter to one-third of the oldest canes to the ground annually to stimulate fresh productive shoots. Remove weak or crossing stems and thin dense sucker growth around the base.
Buffalo Currant is a vigorous, suckering shrub that fruits on second-year and older wood. Annual renewal pruning keeps it productive and prevents it becoming a thicket. Remove the oldest canes at ground level each year and thin excess suckers. It tolerates hard renovation pruning if neglected.

Is it illegal to prune buffalo currant in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check buffalo currant for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
