Which compost astilbe 'bridal veil' needs
For astilbe 'bridal veil' the mix to buy is peat-free multipurpose compost. Wants fertile, water-retentive soil enriched with leaf mould or compost; pH around 6.0-6.5 is ideal. Avoid thin, fast-draining sandy beds that dry out, though it dislikes stagnant waterlogging in winter.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 astilbe 'bridal veil' 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?
Astilbe 'Bridal Veil' is straightforward: an ordinary peat-free multipurpose compost is right. For a big specimen or a pot it will live in for years, mixing in some loam-based John Innes No.2 or No.3 adds weight and holds nutrients longer. Ericaceous compost is not needed unless a plant is specifically a lime-hater.
