More about empire scarlet star in the UK
Which compost empire scarlet star needs
For empire scarlet star the mix to buy is peat-free multipurpose compost. Use a very well-draining, airy mix of fine bark, perlite, and a little peat or coir. The roots of Guzmania are mainly anchoring organs; they do not tolerate waterlogged soil. A commercial bromeliad or epiphyte mix is suitable. The plant can also be mounted on cork or driftwood.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 empire scarlet star 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?
Empire Scarlet Star 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.

Can I use ordinary multipurpose compost for empire scarlet star?
Yes. A good peat-free multipurpose compost is exactly right for empire scarlet star. 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.

Yes. Sales of peat compost to home gardeners are being phased out in the UK, and the RHS recommends peat-free for environmental reasons.

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 empire scarlet star need?
Always a pot with drainage holes. Bromeliad or orchid-bark 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.
