When to prune spiral 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 spiral aloe
Grip dead outer leaves near the base and pull downward firmly, or cut flush to the stem with clean scissors. Do not trim leaf tips.
Spiral Aloe rarely needs pruning. Its iconic spiral rosette is its main feature — never cut into the living rosette structure. Simply remove dead or dried outer leaves at the base as they appear. Avoid trimming the leaf tips; this damages the plant's geometry and leaves unsightly brown cuts.

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.
