UK pruning guide · RHS timing
When to prune scarlet drymonia 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 scarlet drymonia
Cut trailing stems back by one-third to a half above a leaf node after flowering. Pinch out stem tips regularly during active growth to encourage bushier, floriferous branching.
Drymonia coccinea is a trailing tropical gesneriad that benefits from regular pruning to control leggy growth and stimulate flowering. Trim stems back after blooming and pinch tips during the growing season to keep the plant full. Without pruning it can become straggly over time.

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.
