More about eternal flame plant in the UK

Which compost eternal flame plant needs

For eternal flame plant the mix to buy is peat-free multipurpose compost. Use a moisture-retentive yet airy mix, e.g. houseplant compost or peat-based potting soil loosened with around 20% perlite or vermiculite plus 10% orchid bark. Good drainage and aeration prevent the soggy conditions that cause root rot.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 eternal flame plant 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?

Eternal Flame Plant 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.

Compost for Eternal Flame Plant in the UK — frequently asked questions

What compost should I use for eternal flame plant in the UK?

Use peat-free multipurpose compost. Use a moisture-retentive yet airy mix, e.g. houseplant compost or peat-based potting soil loosened with around 20% perlite or vermiculite plus 10% orchid bark. Good drainage and aeration prevent the soggy conditions that cause root rot. 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 eternal flame plant?

Yes. A good peat-free multipurpose compost is exactly right for eternal flame plant. For a large or long-term pot you can mix in some John Innes No.2 or No.3 (loam-based) for extra weight and staying power.

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 eternal flame plant perfectly well — they dry a little faster at the surface, so check moisture by feel rather than by the look of the top.

Does eternal flame plant 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 eternal flame plant need?

Always a pot with drainage holes. Light, well-draining, peat-based aroid/houseplant 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.
