When to prune choisya x dewitteana 'aztec pearl' 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.

Cut back flowered shoots by 25–30 cm (10–12 in) to a healthy bud or leaf. After the final autumn flush, remove any dead or damaged growth only. 'Aztec Pearl' takes well to moderate pruning, increasing density and flower count, but does not need drastic annual cutting.
Yes, prune immediately after flowering. 'Aztec Pearl' has narrower leaves than C. ternata and flowers prolifically in spring, often with a repeat flush in late summer.

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.
