When to prune sheep's fescue 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 sheep's fescue
Run gloved fingers through the clump to pull out brown dead blades, or shear the whole clump back to 2 inches. Remove spent flower stems after summer bloom. Divide every 4–5 years if the center dies out.
Sheep's fescue is a fine-leaved, low-growing bunch grass that needs minimal pruning. A light trim or comb-out in early spring removes dead blades and keeps the mound looking fresh. It is slow-growing and tolerates grazing in nature, so it handles trimming well — but it rarely becomes untidy enough to demand more than a quick tidy.

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.
