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 burpless cucumber

Train to a single main stem; remove all laterals from the lowest 4 nodes entirely. Above that, allow fruiting laterals and pinch them 2 leaves beyond each fruit. Stop the main stem at the top of the support.

Burpless cucumbers are typically trained on a single stem and need regular side-shoot management. Pinch out suckers from the lower nodes, stop the main stem at support height, and remove tired or yellowing leaves promptly. This keeps airflow high and reduces bitter flavors linked to stress and poor ventilation.

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.
