When to prune sinningia concinna 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 sinningia concinna
Pinch off spent flower stalks at the base with fingertips or fine scissors. When leaves yellow and collapse at the start of dormancy, allow them to dry completely before removing them. Never cut or pull away green leaves, as this depletes the tuber.
Sinningia concinna is a miniature gesneriad that needs virtually no pruning. After flowering, remove spent flower stems by pinching or cutting them cleanly at the base. Leaves naturally die back as the plant enters a dormant period — do not cut healthy or semi-green leaves, as the tuber stores energy through them. Resume care when new growth appears.

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.
