When to prune european feather grass 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 european feather grass
Cut the clump to 3–4 inches in late winter using hand shears. Snip off spent plumes individually once they lose their silky appearance. Do not divide clumps unnecessarily — they establish slowly and resent root disturbance.
European feather grass (Stipa pennata) is a protected species in parts of Europe and a graceful cool-season ornamental. It needs a late-winter cut-back to a few inches to clear dead foliage. Remove old flower plumes after they dry to limit self-seeding. Avoid heavy disturbance — this grass dislikes division and hard interference.

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.
