When to prune philodendron cobra 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 philodendron cobra
Cut stems just above a node with sterilised scissors or shears to shorten trailing growth and encourage branching. Remove spent leaves at the petiole base. Tip cuttings can be rooted in water to propagate.
Philodendron 'Cobra' is a vining cultivar that benefits from occasional pruning to keep a tidy shape. Remove yellowing or dead leaves at the petiole base. If long stems trail untidily, cut just above a node to encourage branching. It tolerates light trimming well and cuttings root easily in water.

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.
