When to prune aji amarillo 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 aji amarillo pepper
Pinch the central growing tip just above a leaf node to promote branching. Remove dead or crossing stems with clean, sharp scissors. Overwinter plants can be cut back to a woody framework of 4–6 inches.
Aji Amarillo pepper benefits from early pinching to encourage bushy growth and heavier fruiting. Pinch the main growing tip when the plant reaches 8–12 inches tall. Remove any crossing, dead, or damaged branches during the season. In mild climates where plants overwinter, cut back by about half in late winter to stimulate fresh productive growth.

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.
