When to prune little gem lettuce 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 little gem lettuce
Cut the entire head at ground level when hearts feel firm, or remove individual outer leaves from the base upward, leaving the central rosette to continue growing. Discard any leaves showing signs of tip burn or rot.
Little Gem does not require pruning. It is a compact, fast-maturing cos-type that is harvested whole or as cut-and-come-again. Remove yellowing outer leaves to maintain airflow and reduce disease. In warm spells, harvest promptly before bolting causes bitterness — there is no pruning intervention that prevents bolting.

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.
