When to prune red 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 red currant
Cut oldest stems (3+ years) to the base, leaving around 8–10 healthy stems of mixed ages. Shorten sideshoots to 2–3 buds to build fruiting spurs. Keep the centre open for airflow. On cordons, shorten sideshoots to 1 bud each summer.
Red currants fruit on spurs from two- and three-year-old wood, so pruning is essential for productivity. Each winter, remove the oldest stems (wood older than 3 years), crossing branches, and weak growth to maintain an open, goblet-shaped bush with a balanced mix of one-, two- and three-year stems.

Pruning red currant in the UK — FAQ
When should I prune red currant in the UK?
Prune red currant in early to mid spring. 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.
Is it illegal to prune red 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 red currant for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.
How do you prune red currant?

How often does red currant need pruning in a British garden?
Annually. Red currants fruit on spurs from two- and three-year-old wood, so pruning is essential for productivity. Each winter, remove the oldest stems (wood older than 3 years), crossing branches, and weak growth to maintain an open, goblet-shaped bush with a balanced mix of one-, two- and three-year stems.
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.
