When to prune philodendron mamei 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 mamei
Slice yellowed leaves cleanly at the base of their petiole with a sterile blade. If a stem extends beyond its support, cut back to a node with healthy leaf growth. Wipe the cut with a clean cloth — the milky sap is irritating.
Philodendron mamei is a low-maintenance, slow-creeping terrestrial philodendron that rarely needs pruning. Remove old yellowed or damaged leaves at the base of the petiole as they decline. Occasionally trim a stem that has grown too long back to a node. No aggressive shaping is needed or beneficial.

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.
