Which compost painted fern 'burgundy lace' needs
For painted fern 'burgundy lace' the mix to buy is peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. Likes a leaf-mould or compost-rich woodland soil that holds moisture while draining, slightly acidic to neutral. For containers, blend coir or peat with compost and perlite. Steady moisture without waterlogging keeps the colourful fronds full and healthy.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 painted fern 'burgundy lace' 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?
Painted Fern 'Burgundy Lace' does not want a rich, water-holding compost — it wants sharp drainage. Cut peat-free multipurpose roughly half-and-half with horticultural grit, sharp sand or perlite, and always pot into a container with drainage holes. A "cactus and succulent" bagged mix is a ready-made shortcut.

Use peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite.

Can I use ordinary multipurpose compost for painted fern 'burgundy lace'?
Not on its own — multipurpose compost holds too much water for painted fern 'burgundy lace' and will rot the roots. Cut it roughly 50:50 with horticultural grit, sharp sand or perlite so it drains fast.
Should the compost be peat-free?

Yes — painted fern 'burgundy lace' must have sharp drainage. Add about one part horticultural grit or perlite to one part compost, and always use a pot with drainage holes.
What pot and drainage does painted fern 'burgundy lace' need?
Always a pot with drainage holes. Humus-rich, moisture-retentive, free-draining soil. 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.
