When to prune desert rose 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 desert rose
Using clean, sharp pruners, shorten selected branches by up to one-third, cutting just above a node or growth point. Remove dead or crossing stems entirely. Wash hands and tools after — all parts of Adenium are toxic.
Desert rose benefits from occasional pruning to encourage a fuller crown and more flowering branch tips. Prune lightly in early spring before growth resumes — shorten lanky branches by one-quarter to one-third and remove any crossing or dead stems. Wear gloves: the sap is toxic. Avoid heavy pruning, which stresses the succulent trunk.

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.
