When to prune aloe comosa in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune aloe comosa
Use a sharp, sterilised blade to cut dead leaves flush to the stem. Make one clean cut rather than pulling or tearing to minimise wound area.
Aloe comosa requires minimal pruning. This South African aloe forms a single rosette on a short stem and does not need shaping or cutting back. Maintenance is limited to removing dried, dead, or brown-tipped outer leaves by slicing them off cleanly at the stem. Avoid removing healthy leaves as they support the plant.

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.
