Which compost sweet chariot miniature rose needs
For sweet chariot miniature rose the mix to buy is peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. Use fertile, compost-enriched loam at pH 6.0-6.5. In baskets and pots choose a soil-based peat-free mix with added grit and water-retentive compost to balance fast drainage with moisture.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 sweet chariot miniature rose 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?
Sweet Chariot Miniature Rose does not want a rich, water-holding compost — it wants sharp drainage.

Always a pot with drainage holes. Rich, free-draining loam or quality basket/potting 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.
