Which compost mexican blue palm needs

For mexican blue palm the mix to buy is peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. Needs excellent drainage; thrives in sandy, rocky or poor desert soils and tolerates alkalinity. Wet, heavy soils cause rot, so add plenty of grit on heavier ground. 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 mexican blue palm 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?

Mexican Blue Palm 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.
