When to prune tiger aloe 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 tiger aloe
Cut dried outer leaves as close to the base as possible with a sharp, sterile knife or scissors. Remove spent flower stalks by cutting at the base once all blooms have faded.
Tiger Aloe (Gonialoe variegata) needs very little pruning. The neat, triangular-patterned rosette is naturally tidy. Remove only brown, dried, or damaged outer leaves by cutting them cleanly at the base with a sterile blade. After flowering, cut the spent flower stalk down to the base.

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.
