When to prune tulipa 'purissima' 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 'purissima'
Cut the flower stem off at the base. Leave every leaf untouched until it yellows, flops, and dries completely before removing.
Tulipa 'Purissima' (also sold as 'White Emperor') is a Fosteriana tulip that needs only deadheading after its large cream-white blooms fade. Remove spent flowers to stop seed set. Leave all foliage to die back fully over 6–8 weeks — this is essential for bulb vigor and reliable repeat 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.
