When to prune geogenanthus undatus 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 geogenanthus undatus
Use clean, sharp scissors or pruning snips to cut damaged or yellowed leaves off at the base of the stem, as close to the soil as possible without disturbing roots. No shaping cuts needed.
Geogenanthus undatus rarely needs pruning. Simply remove yellowed, damaged, or dead leaves at the base as they appear. The plant stays naturally compact and low-growing, so no shaping is required. Removing spent foliage keeps it tidy and redirects energy to healthy growth.

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.
