When to prune boea hygroscopica in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune boea hygroscopica
Snap or cut flower stalks cleanly at the base once blooms fade. Remove old or yellowed leaves by cutting or pulling gently at the base of the rosette.
Boea hygroscopica is a small rosette-forming gesneriad related to African violets. It needs very little pruning. Remove spent flower stalks after blooming and cut away any dead or damaged leaves at the base. There is no need to shape or cut back healthy foliage — this plant stays compact naturally.

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.
