When to prune philodendron 'ring of fire' 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 'ring of fire'
Snip spent or damaged leaves off cleanly at the petiole base with sterilized scissors. If redirecting a stem, cut just above a node. Avoid removing healthy mature leaves as they support the plant's energy production.
Philodendron 'Ring of Fire' needs only light maintenance pruning. Remove dead, yellowing, or tatty leaves at the base of the petiole to keep the plant healthy and presentable. Highly variegated new leaves are the main attraction, so avoid cutting back healthy stems unless they are growing in an undesirable direction.

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.
