When to prune sansevieria trifasciata silver hahnii 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 sansevieria trifasciata silver hahnii
Remove unwanted leaves by cutting cleanly at soil level with a sharp, sterile blade. Keep cuts precise to avoid damaging neighbouring leaves in the tight rosette.
Silver Hahnii requires essentially no pruning. This dwarf cultivar forms a tidy, self-contained rosette. Only remove leaves that are rotting, heavily damaged, or dead by cutting at soil level. Avoid trimming leaf tips — any cut edge will turn brown and remains visible permanently.

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.
