When to prune sweet 100 cherry 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 sweet 100 cherry tomato
Regularly pinch out sideshoots in the leaf axils while small, keeping 1–2 main leaders. As an indeterminate variety, it will grow tall — support with stakes and pinch the tip in late summer to direct energy into ripening the last trusses.
Sweet 100 is an indeterminate (cordon) cherry tomato that produces prolifically on sideshoots but benefits from training to 1–2 main stems for manageability. Pinch out sideshoots regularly to prevent excessive sprawl and improve air circulation. Pinch the growing tip 2 leaves above the final truss in late summer to ripen remaining fruit.

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.
