When to prune fordhook lima 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 fordhook lima bean
No pruning required. Allow plants to grow undisturbed. Harvest pods when beans feel firm and round through the pod wall. At season end, cut or pull plants and compost; roots may be left to add nitrogen.
Fordhook lima bean is a large bush type that needs virtually no pruning. It grows to a fixed height and sets pods without intervention. Harvest regularly when pods are plump but seeds not yet hardened. Removing plants at season end is the only cutting typically required.

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.
