When to prune victoria rhubarb 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 victoria rhubarb
Cut flower stalks at the base immediately when they emerge — do not allow them to set seed. In autumn, once leaves die back naturally, clear dead foliage from around the crown to reduce pest and disease habitat. Do not cut healthy green leaves during the harvest season.
Victoria rhubarb rarely needs pruning, but prompt removal of flowering stalks (bolting) is essential — letting them develop weakens the crown and reduces future stem yield. Cut flower stalks to the base as soon as they appear. Remove any dead, yellowed or diseased leaves throughout the season to keep the crown healthy.

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.
