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 eggplant / aubergine

Pinch the crown bud at the first main fork early on. Thin excess shoots to keep 3–5 main branches. In late summer, pinch all growing tips and remove flowers that cannot mature before frost.

Eggplant responds well to pruning for bigger, earlier fruit. Remove the first flower bud ('crown bud') that forms on the main stem fork to encourage branching. Throughout the season, thin to 3–5 main stems, remove suckers, and pinch growing tips in late summer to push energy into fruit already set before frost.

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.
