Which compost cherry of the rio grande needs
For cherry of the rio grande the mix to buy is peat-free ericaceous (lime-free) compost. Adaptable to a range of soil types including sandy soils common in Florida, provided drainage is good. Enrich poor soils with compost at planting. In containers use a well-aerated tropical potting mix with 20–25% perlite.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 cherry of the rio grande 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?
Cherry of the Rio Grande is a lime-hater: it needs an acidic, lime-free ericaceous compost. In ordinary (limey) multipurpose it slowly yellows between the leaf veins as it locks out iron. Buy a bag labelled "ericaceous", and in a hard-water area water with rainwater where you can, since tap water is slightly alkaline.
For the full recipe, pH and drainage detail (US wording), see the cherry of the rio grande soil & potting-mix guide.
Compost for Cherry of the Rio Grande in the UK — frequently asked questions
What compost should I use for cherry of the rio grande in the UK?
Use peat-free ericaceous (lime-free) compost. Adaptable to a range of soil types including sandy soils common in Florida, provided drainage is good. Enrich poor soils with compost at planting. In containers use a well-aerated tropical potting mix with 20–25% perlite. 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 cherry of the rio grande?
No — cherry of the rio grande needs an acidic, lime-free (ericaceous) compost. Standard multipurpose is too limey and will slowly cause yellowing between the leaf veins (lime-induced chlorosis). Buy a bag labelled "ericaceous".
Should the compost be peat-free?
Yes. Sales of peat compost to home gardeners are being phased out in the UK, and the RHS recommends peat-free for environmental reasons. Modern peat-free multipurpose composts grow cherry of the rio grande perfectly well — they dry a little faster at the surface, so check moisture by feel rather than by the look of the top.
Does cherry of the rio grande need grit or perlite added?
Not essential, but a couple of handfuls of perlite in the mix improves aeration and guards against overwatering — useful on a cool, damp British windowsill where compost stays wet longer.
What pot and drainage does cherry of the rio grande need?
Always a pot with drainage holes. Well-drained, slightly acidic sandy loam or loam (pH 5.5–6.5).. 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.
