When to prune passiflora coccinea 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 passiflora coccinea
Cut leading stems back by one-third to one-half using clean, sharp secateurs, cutting just above a leaf node or lateral shoot. Remove entirely any dead, damaged, or congested stems at the base.
Passiflora coccinea is a vigorous tropical climber that needs annual pruning to stay manageable and encourage flowering on new growth. Cut back long, tangled stems by one-third to one-half after the main flush of bloom. Remove dead, crossing, or weak stems entirely to open up the structure and improve airflow.

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.
