When to prune streptocarpus 'chorus line' 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 'chorus line'
Pinch or cut spent flower stalks at the base. For older leaves, remove by cutting cleanly with scissors or pulling gently downward. On very congested crowns, selectively remove the oldest, outermost leaves in early spring to improve light penetration to the centre.
Streptocarpus 'Chorus Line' needs only light tidying rather than true pruning. Deadheading spent flower stalks regularly keeps this prolific bloomer producing new flowers. Remove any yellowing or damaged leaves at the base. This hybrid's vigour means it can go several seasons without more than this light maintenance to stay floriferous and healthy.

Pruning streptocarpus 'chorus line' in the UK — FAQ
When should I prune streptocarpus 'chorus line' in the UK?
Prune streptocarpus 'chorus line' in early to mid spring. 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.
Is it illegal to prune streptocarpus 'chorus line' in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer. Check streptocarpus 'chorus line' for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.
How do you prune streptocarpus 'chorus line'?

How often does streptocarpus 'chorus line' need pruning in a British garden?
Every 2–4 weeks during the growing and flowering season. Streptocarpus 'Chorus Line' needs only light tidying rather than true pruning. Deadheading spent flower stalks regularly keeps this prolific bloomer producing new flowers. Remove any yellowing or damaged leaves at the base. This hybrid's vigour means it can go several seasons without more than this light maintenance to stay floriferous and healthy.
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.
