When to prune aeschynanthus tricolor 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 aeschynanthus tricolor
Cut long, trailing stems back by one-third to one-half using clean scissors. Pinch growing tips on new stems to encourage branching and more flower buds.
Aeschynanthus tricolor (lipstick plant) benefits from pruning after flowering to maintain a full, bushy habit. Leggy stems should be cut back by up to one-half to encourage dense new growth and better flowering. Pinch out stem tips on young plants to promote branching. Remove spent blooms throughout the season.

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.
