Which compost angelonia angustifolia 'serenita raspberry' needs
For angelonia angustifolia 'serenita raspberry' the mix to buy is peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. Prefers a moderately rich, well-drained medium with a slightly acidic to neutral pH (around 5.5-6.5). Waterlogged ground causes root rot; work in compost or use a peat-free container mix with added 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 angelonia angustifolia 'serenita raspberry' 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?
Angelonia angustifolia 'Serenita Raspberry' 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.
