When to prune tulipa 'prinses irene' 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 'prinses irene'
Snap or cut the flower stem at the base once petals drop. Allow all leaves to remain until they are completely yellowed and dried before removing.
Tulipa 'Prinses Irene' is a Triumph tulip that needs only deadheading once its orange-and-purple blooms finish. Remove spent flower heads to stop seed set and direct energy back to bulb replenishment. Leave all foliage to yellow and die back naturally over 6–8 weeks — removing green leaves early weakens the bulb.

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.
