When to prune philodendron selloum (tree philodendron) in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.

Philodendron Selloum (Tree Philodendron) mainly needs dead-leaf removal as lower leaves naturally yellow with age. Remove them by cutting the petiole close to the trunk.

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.
