When to prune orange sinningia 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 orange sinningia
Once leaves yellow and stems collapse post-bloom, cut all top growth back to 1–2 cm above the tuber with clean scissors or pruners. Store the tuber dry and cool through dormancy.
Orange sinningia dies back to a tuber after flowering — cut stems back to near soil level once foliage yellows and the plant enters dormancy. This is seasonal management rather than pruning for shape. When growth resumes in spring, allow new shoots to develop uncut.

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.
