Which compost narrow-leaf bird of paradise needs
For narrow-leaf bird of paradise the mix to buy is peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. Grow in a gritty, loam-based compost with at least 30–40% coarse sand or perlite; good drainage is more important for S. juncea than for any other bird of paradise species.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 narrow-leaf bird of paradise 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?
Narrow-Leaf Bird of Paradise 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.

What compost should I use for narrow-leaf bird of paradise in the UK?
Use peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. Grow in a gritty, loam-based compost with at least 30–40% coarse sand or perlite; good drainage is more important for S. juncea than for any other bird of paradise species. 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 narrow-leaf bird of paradise?
Not on its own — multipurpose compost holds too much water for narrow-leaf bird of paradise and will rot the roots. Cut it roughly 50:50 with horticultural grit, sharp sand or perlite so it drains fast.

Yes — narrow-leaf bird of paradise 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 narrow-leaf bird of paradise need?
Always a pot with drainage holes. Sandy, sharply draining 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.
