When to prune cercestis mirabilis in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.
How to prune cercestis mirabilis
Snip spent leaves at the petiole base with sterilized scissors. To shorten a climbing stem, cut just above a node. Avoid heavy pruning — this slow to moderate grower takes time to recover from significant cuts.
Cercestis mirabilis is a striking African climbing aroid that needs minimal pruning. Remove dead or damaged leaves at the petiole base as they appear. If the climbing stems outpace their support, trim back to a healthy node in spring. The plant's naturally sculptural form is best preserved with a light hand.

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.
