When to prune gardeners delight tomato in the UK

Cordon (indeterminate) varieties like Gardeners Delight need regular pruning to stay productive. Remove sideshoots (suckers) from leaf axils weekly to keep a single main stem, and pinch out the growing tip after 6–7 trusses to redirect energy into ripening fruit before the season ends.

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.
