Which compost sunsatia plus coconut nemesia needs
For sunsatia plus coconut nemesia the mix to buy is peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. Prefers a slightly acidic pH of 5.8-6.5. Incorporate perlite into container mixes for drainage. In borders, avoid heavy clay — dig in organic matter and grit to improve structure before planting.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 sunsatia plus coconut nemesia 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?

Cut peat-free multipurpose roughly half-and-half with horticultural grit, sharp sand or perlite, and always pot into a container with drainage holes.
