When to prune gardenia 'radicans' 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 gardenia 'radicans'
Pinch or snip off faded flowers and trim stray stems back to a healthy leaf node, keeping cuts light (no more than a few centimetres) to maintain the low mounding form.
Gardenia 'Radicans' is a compact, low-growing cultivar that needs only minimal pruning. Deadhead spent flowers and trim any wayward stems immediately after blooming to preserve its naturally neat, spreading habit. Avoid heavy cutting — it sets buds on old wood, so pruning at the wrong time eliminates next season's flowers.

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.
