When to prune crape jasmine 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 crape jasmine
Remove dead or diseased branches first, then lightly thin interior stems to improve light and air circulation. To train as a tree form, steadily remove lowest branches over successive seasons while retaining a clear central leader. Sap is irritating — wear gloves.
Tabernaemontana coronaria (treated as synonymous with T. divaricata in many references) responds well to selective pruning after flowering. Prune to maintain shape, remove dead or diseased wood, and improve airflow. With sustained effort, it can be trained from a shrub into a small tree by gradually removing lower branches.

When should I prune crape jasmine in the UK?
Prune crape jasmine in mid to late spring. 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.
Is it illegal to prune crape jasmine in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check crape jasmine for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
