When to prune elephant bush 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 elephant bush
Use clean, sharp scissors or pruning shears to cut stems back to a node or branching point. For bonsai training, remove crossing branches and shorten long stems by up to one-third. Let cut ends callous for a day before watering. Trimmings root easily as cuttings.
Elephant bush is a vigorous succulent shrub that takes pruning well and actually benefits from it. Trim to maintain the desired shape, encourage branching, and remove leggy or overcrowded growth. It is one of the few succulents where regular light shaping is genuinely useful rather than just removing dead material.

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.
