When to prune philodendron 'white princess' 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 'white princess'
Cut yellowed or dead leaves off at the petiole base. To remove reverting all-green stems, cut just above a node where variegation is still present. Use sterilised pruning shears and wipe the sap — it is a skin irritant.
Philodendron 'White Princess' benefits from occasional pruning to remove yellowed leaves and manage its upright climbing habit. If a stem reverts to all-green growth, cut it back to a variegated node to encourage patterned regrowth. Spring is the best time for any shaping cuts.

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.
