About Meadow Buttercup
Ranunculus acris · also called Meadow Buttercup, Common Buttercup · flowering
Ranunculus acris is a native European and North American perennial wildflower of damp meadows, pastures, and roadside verges, recognisable by its upright, branched stems bearing glossy, bright-yellow flowers with five rounded petals from May to August. It naturalises freely in grass and is an important nectar source for early bumblebees and hoverflies; the double-flowered cultivar 'Flore Pleno' holds the RHS Award of Garden Merit and is a non-seeding garden choice. Keep soil reliably moist and avoid compacted or very dry ground. All parts of the plant are toxic to cats, dogs, horses, and livestock.
Growth habit: Erect, branching herbaceous perennial forming loose clumps; dies back to a basal rosette in winter.
What fertiliser meadow buttercup actually wants — and why
Meadow Buttercup 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 meadow buttercup: 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 meadow buttercup, 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 meadow buttercup:
No feeding required in meadow or naturalistic plantings; a light balanced fertiliser in spring suits the ornamental double form 'Flore Pleno' grown in borders. 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 meadow buttercup 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 meadow buttercup
Half strength is the safe default for meadow buttercup — 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 meadow buttercup first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the meadow buttercup watering schedule.
Signs you are over-feeding meadow buttercup
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for meadow buttercup:
- 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 meadow buttercup
- 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 meadow buttercup care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of meadow buttercup 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 meadow buttercup
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.

What does over-feeding meadow buttercup look like?
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 meadow buttercup 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 meadow buttercup?
Flush the pot of meadow buttercup 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.
