When to prune echinacea 'magnus' 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 echinacea 'magnus'
Remove spent flower stems back to a lateral bud or leaf to promote reblooming. In late winter, cut all remaining stems to 3–4 inches above the crown before new growth emerges.
Echinacea 'Magnus' can be deadheaded after the first flush to encourage more blooms, but leaving seedheads standing into winter feeds goldfinches and other birds. Cut the entire plant back to a few inches above ground in late winter or early spring before new rosettes push up.

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.
