When to prune stapelia grandiflora 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 stapelia grandiflora
Use clean, sharp scissors or a blade to cut dead or spent stems cleanly at soil level. Remove any mushy or blackened stems promptly. Avoid cutting healthy, firm, green stems.
Stapelia grandiflora benefits from occasional light pruning to maintain a compact clump and encourage fresh flowering stems. Remove dead, shrivelled, or rotted stems at the base. After flowering, spent stems can be cut back to the base. Removing congested old growth improves air circulation and reduces rot risk.

Pruning stapelia grandiflora in the UK — FAQ
When should I prune stapelia grandiflora in the UK?
Prune stapelia grandiflora in early to mid spring.

Is it illegal to prune stapelia grandiflora in spring or summer in the UK?
There is no nesting-bird restriction that realistically applies to stapelia grandiflora, since birds do not nest in it. The Wildlife and Countryside Act 1981 still protects any active nest you do find anywhere in the garden — the rule is about the nest, not the plant.

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.
