Which compost spring cinquefoil (potentilla tabernaemontani) needs
For spring cinquefoil (potentilla tabernaemontani) the mix to buy is peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. Replicate the rocky, calcium-rich substrates of its native range by blending loam with at least one-third coarse limestone grit. Nutrient-rich soils produce excessive leafy growth at the expense of flowers and can shorten the plant's life.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 spring cinquefoil (potentilla tabernaemontani) 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?
Spring Cinquefoil (Potentilla tabernaemontani) 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.

Compost for Spring Cinquefoil (Potentilla tabernaemontani) in the UK — frequently asked questions
What compost should I use for spring cinquefoil (potentilla tabernaemontani) in the UK?
Use peat-free multipurpose compost cut roughly half-and-half with horticultural grit or perlite. Replicate the rocky, calcium-rich substrates of its native range by blending loam with at least one-third coarse limestone grit. Nutrient-rich soils produce excessive leafy growth at the expense of flowers and can shorten the plant's life. 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 spring cinquefoil (potentilla tabernaemontani)?
Not on its own — multipurpose compost holds too much water for spring cinquefoil (potentilla tabernaemontani) and will rot the roots. Cut it roughly 50:50 with horticultural grit, sharp sand or perlite so it drains fast.
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 spring cinquefoil (potentilla tabernaemontani) perfectly well — they dry a little faster at the surface, so check moisture by feel rather than by the look of the top.
Does spring cinquefoil (potentilla tabernaemontani) need grit or perlite added?
Yes — spring cinquefoil (potentilla tabernaemontani) must have sharp drainage. Add about one part horticultural grit or perlite to one part compost, and always use a pot with drainage holes.
What pot and drainage does spring cinquefoil (potentilla tabernaemontani) need?
Always a pot with drainage holes. Sharply drained, lean gritty or stony soil, pH 6.5–8.0. 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.
