UK pruning guide · RHS timing
When to prune jonquil 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 jonquil
Pinch or cut the hollow flower stem at its base. Leave every leaf untouched and unbraided until fully brown and easily pulled free.
Jonquils need minimal pruning. Remove spent flower stems after blooming to redirect the plant's energy back into the bulb. Keep all green foliage until it yellows and collapses on its own — usually 6–8 weeks post-bloom. This ripening period is essential for strong flowering next year.

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.
