When to prune fly bush 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 fly bush
Use clean, sharp scissors or pruning snips to remove dead branches at the base and trim leggy stems back by up to one-third to a node or side-shoot. Sterilise blades before use.
Roridula gorgonias is a woody South African carnivorous shrub that can reach 1 m indoors. Light pruning after flowering helps maintain a compact shape. Remove dead or damaged branches in spring. Avoid heavy cutting — it is slow-growing and does not regenerate vigorously from old wood.

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.
