When to prune pea 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 pea
Cut or pinch the main growing tip just above a leaf node when the plant hits the top of the support. Remove dead or diseased leaves by cutting cleanly. There is no benefit to heavy pruning — peas are short-season crops and regrow slowly.
Peas require very little pruning. Pinch out the growing tip of climbing varieties when they reach the top of their support to encourage lateral shoots and extend the cropping period. Remove yellowed or diseased lower leaves to improve airflow. Bush varieties need no pruning. Regular pod harvesting is more important than any cutting.

Is it illegal to prune pea in spring or summer in the UK?

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.
