When to prune sansevieria powellii 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 powellii
Remove unwanted leaves by cutting at soil level with clean, sharp scissors. Never shorten healthy leaves mid-way, as cut edges will not heal cleanly on this species.
Sansevieria Powellii needs almost no pruning as a houseplant. Its upright leaves should be left intact — cutting tips creates permanent brown scars. Pruning is limited to removing completely dead or severely damaged leaves at the base. Beyond that, the plant is best left alone; its natural form is the display.

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.
