When to prune beefsteak tomato 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 beefsteak tomato
Pinch out sideshoots in the leaf axils with your fingers while they are small and soft, leaving a single leader (or two for a double-cordon). In late summer, cut the main growing tip 2 leaves above the topmost flower truss.
Beefsteak tomatoes are indeterminate (cordon) varieties that require regular pinching of sideshoots to maintain a single or double stem and direct energy into producing large fruits. Remove sideshoots weekly when they are small (under 2.5 cm). Pinch out the growing tip in late summer, around 2 leaves above the final truss.

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.
