Which compost dryopteris filix-mas 'linearis polydactyla' needs
For dryopteris filix-mas 'linearis polydactyla' the mix to buy is peat-free multipurpose compost. Thrives in fertile, leafy soil enriched with garden compost or leaf mould. It tolerates neutral to slightly acid or alkaline conditions but resents both drought and stagnant waterlogging.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 dryopteris filix-mas 'linearis polydactyla' 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?
Dryopteris filix-mas 'Linearis Polydactyla' 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.

Use peat-free multipurpose compost. Thrives in fertile, leafy soil enriched with garden compost or leaf mould.

Yes. A good peat-free multipurpose compost is exactly right for dryopteris filix-mas 'linearis polydactyla'. 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?

Modern peat-free multipurpose composts grow dryopteris filix-mas 'linearis polydactyla' perfectly well — they dry a little faster at the surface, so check moisture by feel rather than by the look of the top.
Does dryopteris filix-mas 'linearis polydactyla' need grit or perlite added?

Always a pot with drainage holes. Moist, humus-rich, well-drained woodland 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.
