When to prune saintpaulia 'rob's boolaroo' 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 saintpaulia 'rob's boolaroo'
Snap spent bloom stalks off at the base. Peel yellowing leaves downward and away from the crown. Identify suckers growing between leaf petioles and remove them by twisting or cutting as close to the main stem as possible while still small.
African violets like 'Rob's Boolaroo' benefit from regular light grooming rather than hard pruning. Remove spent flower stalks and faded blooms promptly. Peel away dead or yellowing outer leaves to maintain a single-crown rosette and improve air circulation. Suckers (side shoots) should be removed early to keep one clean crown.

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.
