When to prune reitz's 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 reitz's sinningia
Remove spent blooms by pinching at the stalk base. After dormancy sets in and stems die back, cut all growth to 1–2 cm above the tuber and store dry in a cool location.
Reitz's sinningia is a tuberous flowering species that goes fully dormant after blooming. Cut back dead top growth to just above the tuber once foliage collapses. During the growing season, remove faded flowers to keep the display tidy. No structural pruning is necessary or beneficial.

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.
