When to prune black-seeded melic 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 black-seeded melic
Cut all foliage back to 2–3 inches from ground level with sharp shears. Pick off dead or discoloured leaves as they occur at any time.
Black-Seeded Melic (Melica nutans) is a shade-tolerant woodland grass with minimal pruning needs. It benefits from a single annual cut in late winter to clear old, weathered foliage and promote strong new growth. Outside that, tidy up any dead or damaged leaves as needed through the growing season.

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.
