When to prune beet 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 beet
Snap or cut individual outer leaves at their base for greens, leaving the central crown untouched. At root harvest, twist or cut tops to about 2.5 cm (1 in) above the root to minimise moisture loss. No structural pruning is needed.
Beet does not require pruning. Leaves can be harvested as a bonus salad green by removing a few outer leaves per plant without harming root development. Remove any yellowed or damaged foliage to keep the bed tidy and reduce disease pressure. Once tops are harvested for storage, cut them to about 2.5 cm (1 in) to prevent bleeding.

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.
