When to prune streptocarpus 'falling stars' 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 streptocarpus 'falling stars'
Snap or cut spent flower stems at the base of the plant. Twist and pull dying leaves sideways and downward to remove cleanly without tearing the crown. Do not cut healthy leaves short.
Streptocarpus 'Falling Stars' needs regular deadheading and leaf tidying to keep flowering strongly. Snap off spent flower stalks at the base. Remove old, brown-tipped or dying leaves by twisting them cleanly away. Healthy leaves can be very long — only remove them if they are dying, not just for size.

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.
