When to prune lemmon's marigold 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 lemmon's marigold
In late winter, cut all stems back by one-half to two-thirds using clean, sharp secateurs, cutting just above an outward-facing bud. Deadhead spent flowers during the growing season by removing back to the nearest lateral bud.
Lemmon's marigold is a woody perennial shrub that benefits from annual hard pruning to prevent legginess. Cut it back by up to one-half to two-thirds in late winter or early spring before new growth begins. During the growing season, deadhead regularly to extend flowering, and pinch back shoot tips to encourage a bushier habit.

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 lemmon's marigold 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.
