When to prune aeschynanthus 'rasta' 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 'rasta'
Snip spent-flowering stems back to just above a leaf node, taking no more than 25% of the plant per session. Pinch soft new stem tips during the growing season to encourage branching and more flowering nodes.
Aeschynanthus 'Rasta' (curly lipstick plant) shares the same tip-flowering habit as other Aeschynanthus but its twisted, curling stems make legginess especially visible. Prune after flowers fade, removing up to 25% of stems at a time to avoid cutting off developing buds. Regular deadheading and occasional pinching keep it full and attractive.

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.
