When to prune pinto bean 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 pinto bean
No pruning required. Allow the plant to grow undisturbed. Remove and compost the whole plant once pods are fully dry. Leaving roots in the soil adds nitrogen for the following crop.
Pinto bean is a determinate bush type that sets pods all at once with no need for pruning. Interfering with its growth habit by pinching or trimming can actually reduce the pod crop. Harvest the entire plant when pods are dry and papery, then remove and compost spent plants.

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.
