When to prune tulipa 'tulipa clusiana' 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 'tulipa clusiana'
Pinch or snip off the faded flower head only. Leave the stem and leaves untouched until they are fully dry and straw-coloured before removing.
Tulipa clusiana (the lady tulip) requires very little pruning. Remove spent flower heads after blooming to prevent seeding, but allow all foliage to die back completely and naturally — this is how the slender bulbs store energy to reflower. This species naturalises well and may not need lifting annually in well-drained soils.

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.
