When to prune european columbine 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 european columbine
Snip spent flower stems to the base. Cut the entire plant to ground level after bloom if foliage looks tired — it will regrow. Divide crowns in early spring to maintain vigour and control clump size.
European Columbine is a prolific self-seeder. Deadhead spent flower stems promptly if you want to control spread, or leave them to naturalize. After flowering, cut the whole plant back to the basal rosette when foliage declines — fresh growth regrows quickly. Divide congested clumps every few years.

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.
