When to prune carnation of india 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.
How to prune carnation of india
Prune lightly after flowering, removing spent flower clusters and trimming back overlong or crossing stems to a healthy node. Avoid heavy cuts that expose large amounts of bare wood. Remove dead or diseased branches cleanly. Note: cut stems exude a milky latex — wear gloves.
Carnation of India (Ervatamia coronaria, syn. Tabernaemontana coronaria) is a bushy, branching shrub that responds well to pruning and benefits from a post-flowering tidy to maintain shape, encourage bushier growth, and set up a stronger next bloom. It naturally forms a neat mound but can become open and leggy without occasional cuts.

Is it illegal to prune carnation of india 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 carnation of india 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.
