When to prune swiss chard 'fordhook giant' 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 swiss chard 'fordhook giant'
Cut individual outer leaves cleanly at the base with scissors or a sharp knife, leaving at least 4–5 inner leaves intact. Snap or cut bolt stalks at soil level the moment you spot them to redirect energy back to leaf production.
Swiss Chard 'Fordhook Giant' benefits from regular harvest-pruning rather than ornamental pruning. Remove outer leaves at the base once plants reach 8–10 inches tall, leaving the inner rosette to keep producing. Cut off any yellowing, damaged, or bolting flower stalks promptly to prolong the harvest season.

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.
