When to prune yukon gold 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.
How to prune yukon gold potato
Pinch or cut diseased stems at soil level and dispose of — do not compost blight-affected material. Leave all healthy foliage intact.
Potatoes do not need pruning. Yukon Gold is grown for underground tubers, and the foliage is left to die back naturally at the end of the season, signaling harvest readiness. Remove only dead or severely diseased stems to prevent spread of blight. Never remove healthy green foliage — it powers tuber formation.

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.
