When to prune cuore di bue 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.

Cuore di Bue ('Ox Heart') is a large-fruited indeterminate Italian heirloom. Pruning to a single main stem and removing all suckers consistently produces the largest, most impressive fruits. This variety rewards disciplined suckering more than most — allowing multiple stems leads to smaller fruits and a crowded plant.

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.
