About Shining Cinquefoil
Potentilla nitida · also called Shining Cinquefoil, Pink Rock Cinquefoil · flowering
Potentilla nitida is a specialist high-alpine cinquefoil from the Dolomites and southern Alps, forming tight, silver-silky cushions studded with large, clear pink to deep rose flowers in summer. Its intensely silvered, palmate leaves are covered in silky appressed hairs that give the species its name. One of the most sought-after alpine species for exhibition and specialist troughs.
Growth habit: Dense, tight cushion-forming, woody-based perennial; very slow-growing
What fertiliser shining cinquefoil actually wants — and why
Shining Cinquefoil is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.
A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.
For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for shining cinquefoil: match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.
How often to feed shining cinquefoil, and which months
Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For shining cinquefoil:
No supplementary feeding is required or desirable. Potentilla nitida grows naturally on near-sterile limestone rock with minimal nutrient availability. Any significant fertiliser input creates soft, disease-prone growth incompatible with the species' dense cushion character. The soil structure matters far more than nutrition. Treat that as sparingly through the growing season between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.
The dormant-season rule matters more than the exact interval: skip feeding entirely when shining cinquefoil is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.
What strength to mix for shining cinquefoil
Half strength is the safe default for shining cinquefoil — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.
Feeding always goes onto already-damp soil, never dry roots — water shining cinquefoil first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the shining cinquefoil watering schedule.
Signs you are over-feeding shining cinquefoil
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for shining cinquefoil:
- Brown, crispy leaf tips and edges with no sign of underwatering.
- A white, crusty salt deposit on the soil surface or pot rim.
- Weak, pale, stretched new growth that flops.
- Lower leaves yellow and drop while the soil is correctly watered.
Signs you are under-feeding shining cinquefoil
- Uniformly pale or yellow-green leaves, oldest first.
- Noticeably small new leaves and stalled growth in good light and season.
- A generally tired, lacklustre look despite correct watering and light.
If the symptoms point at watering, light or roots rather than nutrition, the full shining cinquefoil care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of shining cinquefoil with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
Organic vs synthetic feeds for shining cinquefoil
Organic options
A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.
Synthetic / liquid feeds
A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

Brown, crispy leaf tips and edges with no sign of underwatering. A white, crusty salt deposit on the soil surface or pot rim. Weak, pale, stretched new growth that flops. Lower leaves yellow and drop while the soil is correctly watered. Feeding shining cinquefoil year-round on a fixed schedule, including dark winter months, is the most common mistake — it cannot use the nutrients in low light and the surplus simply burns the roots and crusts the soil.
Should I flush the soil of shining cinquefoil?
Flush the pot of shining cinquefoil with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.
