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 dianthus 'doris'

Pinch or snip spent flower stems back to just above a leaf node or sideshoot. After the main flush, shear the plant back by one-third with clean scissors or shears to promote compact, bushy regrowth and additional flowers.

Dianthus 'Doris' (a classic pink) benefits from deadheading after each flush of flowers to encourage repeat blooming through summer. Cut back stems by about one-third after the main flowering period to keep the plant compact and stimulate further blooms. A light trim in early spring tidies over-wintered growth.

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.
