When to prune narrow-leaf coneflower 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 narrow-leaf coneflower
Snip spent flowerheads back to the nearest lateral bud or leaf during summer to encourage more blooms. In late winter, cut all stems to within 2–3 inches of the ground before new basal growth begins.
Narrow-Leaf Coneflower (Echinacea angustifolia) is a prairie perennial that benefits from deadheading to extend blooming. Leaving some spent flowerheads standing through autumn and winter provides seeds for birds and helps the plant self-sow. Cut back all stems to ground level in late winter before new growth emerges.

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.
