When to prune flame violet 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 flame violet
Pinch spent blooms and yellow leaves at the base. Shorten any runners that trail beyond the desired spread by pinching or cutting back to a healthy leaf joint. No hard cutting required.
Flame violet is a low-growing trailing houseplant that needs minimal pruning. Pinch off spent flowers and any yellowing leaves as they appear. If runners become overly long or untidy, trim them back to keep the plant compact and encourage new growth from the centre. There is no structural pruning needed.

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.
