When to prune philodendron 'dean mcdowell' in the UK

Philodendron 'Dean McDowell' rarely needs pruning — it's a slow-growing, sprawling hybrid that doesn't branch like a shrub. Remove any yellow, dead, or damaged leaves at the base with clean scissors. You can trim a stem back to control spread, but this hybrid produces few stems so do so sparingly.

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.
