When to prune aeschynanthus 'mona lisa' 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.

Aeschynanthus 'Mona Lisa' is a free-flowering lipstick plant that benefits from a light post-bloom trim to prevent leggy trailing stems and encourage denser growth with more tip-flowering shoots. Flowers form at stem tips, so never prune before bloom. Deadhead spent flowers promptly to keep the plant tidy.

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.
