When to prune aloe castillon 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 castillon
Remove dead outer leaves by pulling them downward or cutting at the base. Remove flower stalks at the base once blooms fade using clean, sharp scissors.
Aloe castilloniae is a less common compact aloe that requires minimal pruning. Remove dead or withered outer leaves at the base as they appear. Cut spent flower stalks flush to the base after blooming. Avoid shaping or trimming the rosette; cut leaf tips turn brown and do not regenerate.

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.
