When to prune yellow cone plant 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 yellow cone plant
Peel the papery remnant sheath away by hand. If it resists, leave it — it will finish drying naturally. Never use scissors on the succulent bodies.
Yellow Cone Plant (Conophytum flavum) needs minimal pruning. Each year the old body shrivels into a papery sheath that protects the new growth. Remove this dry sheath only once it is completely desiccated. Do not cut into the fleshy bodies — this mesemb manages its own renewal without intervention.

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.
