When to prune pepper in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune pepper
Pinch the central growing tip just above a leaf node when the plant has 4-6 true leaves to promote branching. During the season, snap or cut off dead or damaged stems. For overwintering, cut the plant back to the main framework of stems in autumn, leaving 3-5 inches of stem.
Pepper plants benefit from light pruning but don't need heavy cutting. Pinch the growing tip of young plants to encourage branching and a bushy habit before transplanting. Once fruiting begins, remove any stems that are crossing, dead, or crowding airflow. Some growers cut plants back hard in autumn to overwinter them indoors.

Pruning pepper in the UK — FAQ
When should I prune pepper in the UK?
Prune pepper in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
Is it illegal to prune pepper in spring or summer in the UK?
There is no nesting-bird restriction that realistically applies to pepper, since birds do not nest in it. The Wildlife and Countryside Act 1981 still protects any active nest you do find anywhere in the garden — the rule is about the nest, not the plant.
How do you prune pepper?

How often does pepper need pruning in a British garden?

Some growers cut plants back hard in autumn to overwinter them indoors.
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.
