When to prune choisya 'white dazzler' in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune choisya 'white dazzler'
Trim back flowered shoots by up to one-third using sharp secateurs, cutting just above a leaf node. Remove dead or frost-damaged wood back to healthy green growth. Avoid cutting into thick, old, leafless stems.
Choisya 'White Dazzler' (Mexican orange blossom) benefits from a light prune after each flush of flowers to keep it compact and encourage a second flush. Avoid cutting into old bare wood as it may not re-shoot freely. Remove any frost-damaged or dead shoots in spring once new growth shows where the damage ends.

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.
