When to prune spiritus sancti 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 spiritus sancti
Remove dead leaves by cutting cleanly at the petiole base with sterile scissors. Provide a tall moss pole or plank to encourage the elongated, pendant leaves characteristic of mature climbing growth. Do not remove healthy stems or growing tips.
Spiritus Sancti is one of the rarest Philodendrons in cultivation. It needs essentially no pruning — remove only dead or damaged leaves at the petiole base. Never cut healthy stems; each node is precious and irreplaceable on this critically endangered species. Prioritize climbing support over any shaping.

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.
