UK pruning guide · RHS timing
When to prune paperwhite narcissus 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 paperwhite narcissus
Snap off spent flower stems at the base. Leave all strap-like leaves intact until they die back on their own. For forced indoor bulbs, discard the spent plant after bloom.
Paperwhites grown indoors for winter forcing are typically discarded after bloom, as they rarely re-flower well. If grown in garden borders in mild climates, deadhead after flowering and allow foliage to yellow naturally before removing. No other pruning is needed — the foliage feeds the bulb for future seasons.

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.
