When to prune golden fescue in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune golden fescue
Run gloved fingers through the clump to pull out dead blades, or lightly trim with scissors to about two-thirds of the plant height. Never scalp to ground level. When the centre becomes brown and dead (typical after 2–3 years), lift and divide, replanting only vigorous outer sections.
Golden fescue (Festuca glauca 'Golden Toupee') benefits from a light annual comb-out or trim in early spring to remove winter-dead blades. Unlike some grasses, it should not be cut hard to the ground — trim to about one-third of height at most. Divide every 2–3 years when the centre dies out.

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.
