When to prune meadow oat 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 meadow oat grass
Wear gloves and run fingers through the clump to tease out dead leaves. Only trim with shears if the plant looks very untidy, cutting minimally to avoid damaging live growth at the crown.
Meadow Oat Grass is semi-evergreen to evergreen and rarely needs hard pruning. In early spring, remove dead or brown leaves by hand-combing the clump. Trim lightly if the plant looks untidy, but avoid aggressive cutting — this grass resents hard pruning and recovers slowly.

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.
