When to prune lantana 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 lantana
In early spring, cut all stems back by half to two-thirds, removing woody older growth to leave a low, branched framework. During the growing season, snip off spent flower clusters to prevent fruiting and redirect energy to new blooms. Tip-pinch young shoots to increase branching.
Lantana blooms on new growth and needs regular pruning to stay compact and flower freely. Without it, plants become woody and bloom poorly. Deadhead spent flower heads continuously, tip-prune through the season, and cut back hard in early spring to renew the plant's framework and stimulate vigorous flowering shoots.

Pruning lantana in the UK — FAQ
When should I prune lantana in the UK?
Prune lantana 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 lantana 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 lantana 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 lantana?

How often does lantana need pruning in a British garden?
Hard prune once annually; deadhead weekly during blooming season. Lantana blooms on new growth and needs regular pruning to stay compact and flower freely. Without it, plants become woody and bloom poorly. Deadhead spent flower heads continuously, tip-prune through the season, and cut back hard in early spring to renew the plant's framework and stimulate vigorous flowering shoots.
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.
