When to prune fritillaria meleagris 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 fritillaria meleagris
Snap off spent flower heads at the stem top if seed spread is unwanted. Otherwise leave the whole plant to die back undisturbed. No further pruning is needed.
Snake's head fritillary requires very little pruning. Remove spent flowers after blooming in mid-spring if you want to limit self-seeding — though allowing seed to scatter is the best way to naturalise this species in grass or borders. Always let foliage die back fully and naturally before removing it. Avoid disturbing the small bulbs.

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.
