When to prune fish 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 fish pepper
Pinch the first flower buds before the plant has 6–8 true leaves to build a stronger frame. Snip out any dead or diseased growth with clean scissors throughout the season.
Fish Pepper, a heritage hot pepper, benefits from the same light pruning as other Capsicum annuum varieties. Pinch early flower buds on young plants to promote bushy growth. Remove dead wood or crossing branches to maintain airflow. Beyond that, this vigorous heirloom needs little structured pruning.

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.
