When to prune pseudolithos cubiformis 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 pseudolithos cubiformis
Use sterilised tweezers or fine scissors to remove shrivelled or necrotic surface tissue only. Do not cut into healthy green or grey-green body tissue. Allow any cut to dry before watering resumes.
Pseudolithos cubiformis is an extremely rare, slow-growing succulent with a cube-like body. It requires no pruning whatsoever. The entire plant is a single geometrically compact stem. Simply remove any withered or dead tissue carefully. Any cutting of healthy tissue is harmful and unnecessary.

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.
