When to prune fairy fan-flower 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 fairy fan-flower
Pinch the tips of young shoots to just above a leaf node to encourage branching. For established plants, use scissors to trim overly long or leggy stems back by one-quarter to promote compact, bushy regrowth.
Scaevola aemula performs well with light, regular trimming rather than heavy pruning. Pinch growing tips on young plants to encourage bushiness. Deadheading is useful but not always necessary — the plant tends to be self-cleaning. When stems get leggy, trim back lightly by one-quarter to one-third to refresh growth and maintain a tidy mounding habit.

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.
