When to prune drymonia serrulata 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 drymonia serrulata
Cut back overgrown or bare stems by one-quarter to one-third to a leaf node with clean scissors. Remove any dead, damaged, or crossing stems at the base. Provide support for remaining climbing stems.
Drymonia serrulata is a tropical climbing or trailing gesneriad. Prune after flowering to keep growth manageable and encourage branching. Cut back long, bare stems to a healthy node to stimulate bushier regrowth. Without occasional trimming it can become unruly, but it responds well to moderate cutting.

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.
