When to prune russian banana fingerling potato 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.

Snip diseased stems at soil level with disinfected scissors and dispose of (do not compost). Leave all healthy foliage untouched.
Russian Banana fingerling potato needs no pruning. Foliage is left intact to die back naturally, signaling tuber maturity. The only exception is prompt removal of blight-affected or diseased stems to reduce spread. Cutting healthy green tops early reduces yield significantly, so resist the urge to tidy the plant mid-season.

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.
