When to prune weeping love 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 weeping love grass
Cut all old stems to 3–4 inches above the crown. In mild climates, comb out dead leaves rather than cutting the whole clump back hard, to avoid removing live growth.
Weeping Love Grass is a warm-season, semi-evergreen to evergreen clump-former. Cut stems back to a few inches above the crown in late winter to encourage fresh, tidy growth. In frost-free climates it remains semi-green year-round — remove dead and brown material as needed rather than cutting hard.

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.
