When to prune lipstick plant 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 lipstick plant
Using clean scissors, cut trailing stems back by one-third to one-half, cutting just above a leaf node. Remove any bare or dead stems entirely at their base. Avoid cutting back into completely leafless woody sections, as regrowth there is slow.
Lipstick plants flower on new growth, so light pruning after each flowering flush directly encourages more blooms. Trim back long, trailing stems by one-third to one-half after flowers fade. This keeps the plant compact and bushy and prevents bare, woody stems from dominating the basket or pot.

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.
