When to prune double pinwheel flower 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 double pinwheel flower
Cut leggy stems back by up to one-third using clean, sharp shears. Deadhead spent flower clusters at the node. Remove any crossing or inward-facing branches to open the canopy and improve airflow.
Double Pinwheel Flower benefits from light pruning to maintain shape and encourage bushy growth. After flowering flushes, trim back leggy stems by one-third. Remove spent blooms and any crossing branches. It blooms on new growth, so regular light shaping keeps it productive. Without pruning it becomes open and straggly over time.

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.
