When to prune galangal 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 galangal
Cut dead or old canes down to soil level with clean loppers or shears. Leave healthy green canes intact. If clumps are overcrowded, dig and divide the rhizomes rather than pruning tops.
Galangal (Alpinia galanga) is a large rhizomatous ginger relative that rarely needs pruning beyond tidying. Cut old, yellowing or dead stems to the ground any time. In late winter or early spring, remove the previous season's spent stalks entirely to make room for new growth. Division every 3–4 years is more useful than pruning.

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.
