Which compost anthurium crystallinum x magnificum needs
For anthurium crystallinum x magnificum the mix to buy is peat-free multipurpose compost. Pot in an airy blend of orchid bark, perlite, charcoal and sphagnum that drains fast yet holds light moisture. Avoid heavy peat soils, which compact and suffocate the roots of these semi-epiphytic anthuriums.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 anthurium crystallinum x magnificum 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?
Anthurium crystallinum x magnificum is straightforward: an ordinary peat-free multipurpose compost is right. For a big specimen or a pot it will live in for years, mixing in some loam-based John Innes No.2 or No.3 adds weight and holds nutrients longer. Ericaceous compost is not needed unless a plant is specifically a lime-hater.

What compost should I use for anthurium crystallinum x magnificum in the UK?

Can I use ordinary multipurpose compost for anthurium crystallinum x magnificum?
Yes. A good peat-free multipurpose compost is exactly right for anthurium crystallinum x magnificum. For a large or long-term pot you can mix in some John Innes No.2 or No.3 (loam-based) for extra weight and staying power.

Does anthurium crystallinum x magnificum need grit or perlite added?
Not essential, but a couple of handfuls of perlite in the mix improves aeration and guards against overwatering — useful on a cool, damp British windowsill where compost stays wet longer.
What pot and drainage does anthurium crystallinum x magnificum need?
Always a pot with drainage holes. Coarse aroid mix. Stand it on a saucer, empty any water that collects after watering, and never leave the pot sitting in a full outer cover — waterlogged compost in a cool UK room is the commonest cause of root rot.
