When to prune red arrow arrowhead vine 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 red arrow arrowhead vine
Snip individual stems back to a node just above the soil or wherever a side shoot is visible. Remove entire yellowing leaves (stem and blade) cleanly at the base rather than tearing.
Syngonium erythrophyllum requires very little pruning. Remove dead, yellowed, or damaged leaves at the base as they occur. If vines grow beyond the desired length, trim stems back to any node — the plant will branch from that point. Pruning is cosmetic rather than essential for this slow-to-moderate grower.

Prune red arrow arrowhead vine in spring, once growth resumes. British pruning timing is set by the last frost rather than the calendar.

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.
