When to prune noble aeonium 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 noble aeonium
Pull away dried lower leaves by hand — do not cut into the rosette. After a rosette has flowered and died, cut the spent stem back to the main body to allow any remaining offsets or side-shoots to develop.
Noble Aeonium (Aeonium nobile) is a large, single-stemmed or sparsely branched succulent with impressive rosettes. It needs very little pruning — remove dead or damaged lower leaves by pulling them away cleanly. If kept for many years, trim the stem to encourage offsets. Individual rosettes are monocarpic and die after their impressive flower spike.

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.
