When to prune trailing african daisy 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 trailing african daisy
Remove spent blooms regularly. For a seasonal tidy, shorten trailing stems by up to one-third with clean shears, cutting above a healthy leaf node. Avoid cutting back into completely bare, leafless stem sections as regrowth from bare wood is unreliable.
Trailing African daisy (Osteospermum fruticosum) needs deadheading for best flowering and occasional trimming to stop stems becoming too long and bare at the base. Cut trailing stems back by up to one-third in midsummer to keep plants tidy. In mild climates where it overwinters, a harder spring trim removes frost-damaged or woody growth.

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.
