When to prune sansevieria kirkii 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 kirkii
Slice dead or rotted leaves cleanly at soil level using a sterilized knife. For minor brown tips, leave them rather than cutting — trimming creates a wider brown margin over time.
Sansevieria kirkii needs very little pruning. Its broad, wavy-edged leaves grow from a rosette and do not need shaping. Remove any leaves that have rotted or died completely by cutting at the base. Partial cuts on healthy leaves create permanent brown scars, so avoid them.

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.
