Which compost colocasia colocasia gigantea thailand giant needs

For colocasia colocasia gigantea thailand giant the mix to buy is peat-free multipurpose compost. Use a deep, fertile, humus-rich mix with plenty of compost or rotted manure; it tolerates clay and waterlogging and grows happily in shallow pond margins. Lean, dry soil severely limits its size. 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 colocasia colocasia gigantea thailand giant 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?

Colocasia Colocasia Gigantea Thailand Giant 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.
