When to prune morning light maiden 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 morning light maiden grass
Tie the clump into a bundle, then cut the entire clump back to 4–6 inches above ground using loppers or a hedge trimmer. Remove all cut material.
Morning Light Maiden Grass should be cut back hard once a year in late winter or very early spring before new shoots emerge. Leave the clump standing through autumn and winter — the feathery plumes provide ornamental interest and shelter. Cut to about 4–6 inches above ground level.

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.
