Which compost schmitz's cycad needs
For schmitz's cycad the mix to buy is peat-free ericaceous (lime-free) compost. A blend of 35% coarse grit or perlite, 35% quality loam, and 30% well-composted bark or leaf mould reflects its forest floor origins. pH 5.5–6.5. The organic component retains enough moisture between waterings while the grit fraction ensures rapid drainage. Avoid compacted or clay-heavy substrates.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 schmitz's cycad 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?
Schmitz's Cycad is a lime-hater: it needs an acidic, lime-free ericaceous compost. In ordinary (limey) multipurpose it slowly yellows between the leaf veins as it locks out iron. Buy a bag labelled "ericaceous", and in a hard-water area water with rainwater where you can, since tap water is slightly alkaline.

Compost for Schmitz's Cycad in the UK — frequently asked questions
What compost should I use for schmitz's cycad in the UK?
Use peat-free ericaceous (lime-free) compost. A blend of 35% coarse grit or perlite, 35% quality loam, and 30% well-composted bark or leaf mould reflects its forest floor origins. pH 5.5–6.5. The organic component retains enough moisture between waterings while the grit fraction ensures rapid drainage. Avoid compacted or clay-heavy substrates. In UK garden centres this is sold simply as "compost" — the bagged growing medium, not garden-made leaf-mould — so match the description above rather than a brand.
Can I use ordinary multipurpose compost for schmitz's cycad?
No — schmitz's cycad needs an acidic, lime-free (ericaceous) compost. Standard multipurpose is too limey and will slowly cause yellowing between the leaf veins (lime-induced chlorosis). Buy a bag labelled "ericaceous".
Should the compost be peat-free?
Yes. Sales of peat compost to home gardeners are being phased out in the UK, and the RHS recommends peat-free for environmental reasons. Modern peat-free multipurpose composts grow schmitz's cycad perfectly well — they dry a little faster at the surface, so check moisture by feel rather than by the look of the top.
Does schmitz's cycad need grit or perlite added?
Not essential, but a couple of handfuls of perlite in the mix improves aeration and guards against overwatering — useful on a cool, damp British windowsill where compost stays wet longer.
What pot and drainage does schmitz's cycad need?
Always a pot with drainage holes. Humus-rich, free-draining forest mix. Stand it on a saucer, empty any water that collects after watering, and never leave the pot sitting in a full outer cover — waterlogged compost in a cool UK room is the commonest cause of root rot.
