Which compost restrepia guttulata needs
For restrepia guttulata the mix to buy is peat-free multipurpose compost. Pot in fresh sphagnum in a small container, or mount on cork or tree fern with a moss pad. The medium must stay open and damp; renew sphagnum yearly before it breaks down and sours, since decayed moss rapidly rots the delicate root system.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 restrepia guttulata 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?
Restrepia guttulata 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.

Compost for Restrepia guttulata in the UK — frequently asked questions
What compost should I use for restrepia guttulata in the UK?
Use peat-free multipurpose compost. Pot in fresh sphagnum in a small container, or mount on cork or tree fern with a moss pad. The medium must stay open and damp; renew sphagnum yearly before it breaks down and sours, since decayed moss rapidly rots the delicate root system. In UK garden centres this is sold simply as "compost" — the bagged growing medium, not garden-made leaf-mould — so match the description above rather than a brand.
Can I use ordinary multipurpose compost for restrepia guttulata?
Yes. A good peat-free multipurpose compost is exactly right for restrepia guttulata. 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.
Should the compost be peat-free?
Yes. Sales of peat compost to home gardeners are being phased out in the UK, and the RHS recommends peat-free for environmental reasons. Modern peat-free multipurpose composts grow restrepia guttulata perfectly well — they dry a little faster at the surface, so check moisture by feel rather than by the look of the top.
Does restrepia guttulata 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 restrepia guttulata need?
Always a pot with drainage holes. Fresh sphagnum moss or fine bark mix, or mounted. 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.
