When to prune maire's 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 maire's fescue
Rake through the clump with a gloved hand or wide-tooth comb to pull out dead blades, then trim ragged tips with shears to a uniform height. A harder cut to 4–5 inches is safe if the clump looks untidy after a harsh winter.
Maire's fescue is a robust, semi-evergreen clumping grass that stays relatively tidy. It benefits from an annual comb-out or light trim in early spring to remove winter-damaged tips and any dead inner blades. Because it is larger and tougher than most fescues, it tolerates a harder cut but rarely needs one.

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.
