When to prune red frangipani 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 red frangipani
Cut dead or diseased branches back to healthy wood, making cuts just above a node or lateral branch. To reduce height, shorten selected branches by no more than one-third. Avoid removing too many branch tips, as flowers form at growing points.
Red Frangipani requires only light pruning — it flowers at the tips of branches, so over-pruning removes next season's buds. Remove dead, damaged, or crossing branches in late winter while the tree is dormant. Shorten excessively long branches to shape. Wear gloves: the milky sap is a skin irritant.

Pruning red frangipani in the UK — FAQ
When should I prune red frangipani in the UK?
Prune red frangipani in early to mid spring. 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.
Is it illegal to prune red frangipani 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 red frangipani for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.
How do you prune red frangipani?

How often does red frangipani need pruning in a British garden?
Annually in late winter; otherwise only as needed. Red Frangipani requires only light pruning — it flowers at the tips of branches, so over-pruning removes next season's buds. Remove dead, damaged, or crossing branches in late winter while the tree is dormant. Shorten excessively long branches to shape. Wear gloves: the milky sap is a skin irritant.
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.
