Which compost calathea lutea (cuban cigar) needs
For calathea lutea (cuban cigar) the mix to buy is peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. Fertile, humus-rich, water-retentive soil that stays damp; it thrives along streams and wet ground in the wild. Indoors use a heavy, organic, free-draining potting mix. Tolerates a wide pH but prefers slightly acidic to neutral.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 calathea lutea (cuban cigar) 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?
Calathea Lutea (Cuban Cigar) 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.

Not on its own — multipurpose compost holds too much water for calathea lutea (cuban cigar) 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?

Always a pot with drainage holes. Rich, moisture-retentive loam. 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.
