When to prune dwarf tulip 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 dwarf tulip
Remove faded flower heads by snapping them off just below the seed capsule. Leave all foliage — even as it yellows — completely undisturbed until it is fully withered and dry, ensuring the bulb stores energy for the following season.
Dwarf tulips (Tulipa humilis) are compact species tulips that naturalise in well-drained spots and need minimal pruning. Deadhead spent flowers to avoid wasting energy on seed production, then leave the small leaves to die back naturally over 4–6 weeks. No cutting back or dividing is usually required.

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.
