When to prune 'borlotto' 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 'borlotto' bean
Snip the growing tip cleanly above a leaf node if the plant exceeds its support. For fresh borlotto, harvest when pods are plump and streaked red-and-cream. For dried beans, leave pods to fully mature and dry on the plant.
'Borlotto Lingua di Fuoco' is typically grown as a bushy climbing or semi-climbing annual. It needs very little pruning. Pinch out the tip if it overtops its support. The main 'pruning' task is regular pod harvesting — leaving pods to mature fully signals the plant to stop flowering. Remove spent foliage as it yellows.

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.
