When to prune becky shasta daisy 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 becky shasta daisy
Remove spent flowers cutting back to the nearest side bud or healthy leaf. After peak bloom, cut the whole clump back by roughly half. In late autumn, cut all stems to 2–3 inches above ground level.
'Becky' is a tall, robust Shasta daisy cultivar that blooms reliably from midsummer. Deadhead spent blooms regularly to extend the season. Cut back by half after the main flush to encourage re-bloom. In late autumn, cut stems to ground level. Divide congested clumps every 2–3 years to maintain the strong upright habit.

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.
