When to prune sinningia eumorpha 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 eumorpha
Pinch or cut spent flower stalks at their base. Allow foliage to yellow and collapse naturally before trimming. Once fully dry, remove old stems cleanly at soil level. When repotting in spring before new growth begins, trim any soft or rotted roots from the tuber with clean, sharp scissors.
Sinningia eumorpha needs only light pruning. Remove spent flower stalks at the base after blooms fade to keep the plant tidy and encourage further flowering. When the plant enters dormancy, allow stems and leaves to die back naturally before removing them. Do not cut live, green stems — the tuber needs them to complete its energy storage cycle.

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.
