Which compost urn plant (aechmea fasciata) needs
For urn plant (aechmea fasciata) the mix to buy is peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. Use a chunky, fast-draining medium such as an orchid or bromeliad mix, or a blend of bark, perlite and a little peat-free compost. Standard potting soil holds too much water and invites root rot. The plant has a small root system used mostly for anchorage.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 urn plant (aechmea fasciata) 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?
Urn Plant (Aechmea fasciata) 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.
