When to prune aeschynanthus lobbianus 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 lobbianus
With clean, sharp scissors cut spent-flowering stems back to roughly 15–20 cm, just above a leaf node. Remove no more than one-third of total growth at once to avoid stressing the plant.
Aeschynanthus lobbianus (lipstick plant) flowers at stem tips, so pruning should follow bloom cycles rather than precede them. Cut stems back by up to one-third after flowers fade to prevent legginess and encourage branching. This produces the new tip growth that carries next season's buds. Remove dead or yellowed leaves at any 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.
