When to prune golden angel's trumpet 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 golden angel's trumpet
Cut leggy or older branches back to ½ in above a node. Preserve established Y-junctions and leave 6–10 nodes above each fork. Thin dense areas for airflow and remove dead or diseased wood entirely.
Brugmansia aurea produces flowers on new wood, so annual pruning is key to a good display. Prune in early spring or late winter to shape the plant, remove winter damage, and stimulate branching. Like all Brugmansia, it tolerates hard cutting but needs time to re-establish its flowering Y-junctions. Wear gloves — all parts are toxic.

When should I prune golden angel's trumpet in the UK?
Prune golden angel's trumpet in early to mid spring.

Is it illegal to prune golden angel's trumpet 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 golden angel's trumpet for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

How often does golden angel's trumpet need pruning in a British garden?
Annually; optional light tip-pruning during the growing season to encourage branching. Brugmansia aurea produces flowers on new wood, so annual pruning is key to a good display. Prune in early spring or late winter to shape the plant, remove winter damage, and stimulate branching. Like all Brugmansia, it tolerates hard cutting but needs time to re-establish its flowering Y-junctions. Wear gloves — all parts are toxic.
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.
