When to prune arrowhead plant in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune arrowhead plant
Cut long trailing or climbing stems back to a preferred length, making cuts just above a leaf node. Remove individual yellow or brown leaves by pulling them cleanly from the stem. Cuttings with two or more nodes root readily in water.
Arrowhead plant benefits from regular pruning to control its vining habit and encourage compact, bushy growth. Without pruning, stems elongate and the plant becomes sparse at the base. Trim back long vines and remove any yellow or damaged leaves throughout the year. Pruned cuttings root easily in water for propagation.

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.
