When to prune 'brandywine' 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 'brandywine' tomato
Pinch suckers by hand when they are under 5 cm (2 in) to avoid open wounds. Maintain 1–2 stems on a sturdy stake or cage. Remove leaves that show yellowing or touch the ground to reduce disease entry points.
'Brandywine' is an indeterminate heirloom tomato and one of the most vigorous growers; pruning is essential. Remove suckers consistently to maintain 1–2 leaders, which focuses energy on the large beefsteak fruits this variety is prized for. Unpruned plants produce excessive foliage at the expense of fruit size and quality.

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.
