When to prune roma 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 roma tomato
Once 4–6 flower trusses have set on the main stems, pinch or cut out the growing tip. Snap off yellowing or diseased lower leaves cleanly at the stem throughout the growing season.
Roma tomato is a determinate (bush) type — do not aggressively remove sideshoots as you would with indeterminate varieties, as it sets fruit on side branches. Pinch out the growing tip once the plant has set several flower trusses to direct energy into fruit. Remove lower yellowing leaves to improve airflow and reduce disease.

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.
