When to prune tulipa 'queen of night' 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 tulipa 'queen of night'
Snap or cut the spent flower head off at the top of the stem, leaving the stem and all leaves in place. Allow the foliage to die back completely on its own before removing it. Do not cut, braid, or cover the leaves while they are still green.
Tulipa 'Queen of Night' needs minimal pruning. After flowering, deadhead to prevent seed set, but leave all foliage intact until it has yellowed and died back naturally — this is essential for the bulb to store energy for next year's bloom. Never cut or tie back green leaves; doing so weakens future flowering.

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.
