When to prune impala lily 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 impala lily
Remove dead or crossing branches with clean, sharp pruners. To encourage branching, cut a stem tip back to a node. Let all cut surfaces air-dry and callous before watering resumes.
Impala Lily (Adenium multiflorum) is a naturally compact, slow-growing succulent shrub that rarely needs pruning. Its main flowering season is winter (when deciduous in its native habitat). Prune only to remove dead wood or to encourage branching on leggy young specimens. All parts are highly toxic — wear gloves throughout.

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.
