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 aerangis biloba

Snip spent inflorescences to the base with sterilised scissors. Remove dead leaves at the point they meet the stem. All healthy aerial roots should remain intact.

Aerangis biloba requires very little pruning. This small epiphytic orchid benefits only from removal of spent flower spikes once blooms drop and the occasional clean-up of dead or damaged leaves. Do not cut healthy aerial roots — they absorb humidity and anchor the plant. No routine pruning schedule is needed.

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.
