Which compost philodendron pedatum (oak leaf) needs
For philodendron pedatum (oak leaf) the mix to buy is peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. Wants a loose, organic-rich medium that holds some moisture while staying airy. Combine standard potting compost with orchid bark, perlite and a little horticultural charcoal so the roots get plenty of air pockets. A pot with drainage holes is essential to prevent root rot.In British garden centres the bagged growing medium is sold simply as “compost” (multipurpose, ericaceous, or loam-based John Innes), which is a different thing from the rotted garden “compost” you make in a heap — for a pot you want the bagged kind.
Peat-free compost
Buy peat-free. The sale of peat compost to home gardeners is being phased out across the UK, and the RHS recommends peat-free on environmental grounds. A good peat-free multipurpose grows philodendron pedatum (oak leaf) perfectly well; the one habit to change is watering — peat-free dries faster at the surface while still moist below, so check by feel a knuckle deep rather than trusting the look of the top.
Ericaceous or multipurpose?

Cut peat-free multipurpose roughly half-and-half with horticultural grit, sharp sand or perlite, and always pot into a container with drainage holes.
