When to prune greek sage 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 greek sage
After blooms fade, shorten stems by one-third using clean secateurs, cutting to just above a healthy leaf or bud. In spring, remove dead or frost-damaged stems and lightly shape the overall form. Do not cut back hard into bare wood.
Greek Sage is a woody, shrubby perennial that benefits from regular pruning to prevent it becoming leggy and woody at the base. Cut back by up to one-third after flowering in early summer. In early spring, prune lightly to shape, removing any dead or frost-damaged wood. Avoid cutting into old, leafless wood as it may not regenerate.

Is it illegal to prune greek sage in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check greek sage for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
