UK pruning guide · RHS timing
When to prune aloe dorotheae 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 dorotheae
Pull or cut dead outer leaves at the base. Remove spent flower stalks at the base with clean pruners. No shaping of the rosette is needed or beneficial.
Aloe dorotheae turns vivid red-orange in strong sun and is grown for its striking rosette. It needs almost no pruning — remove dead outer leaves at the base and cut spent flower stalks after blooming. Avoid trimming leaf tips; cut aloe tips turn brown permanently and mar the rosette's appearance.

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.
