When to prune argyroderma pearsonii 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 argyroderma pearsonii
Gently remove the completely dry, papery husk by hand. No cutting tools required or recommended.
Argyroderma pearsonii needs no pruning. This South African stone plant grows as a single fused leaf pair that is replaced each year from within. The old pair dries naturally; remove it by hand once fully papery. Cutting into any living tissue is harmful — this plant's entire water supply is stored in its leaves.

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.
