About Achillea millefolium 'Cerise Queen'
Achillea millefolium 'Cerise Queen' · also called Cerise Queen yarrow · flowering
A vivid common-yarrow selection bearing flat heads of cerise-pink flowers with pale centers above ferny, aromatic green foliage all summer. 'Cerise Queen' is tough, drought-tolerant, and pollinator-friendly, spreading readily to fill sunny borders and wildflower plantings. Flowers fade with age, giving a multi-toned look, and dry well for arrangements.
Growth habit: Vigorous, spreading clump-forming herbaceous perennial with ferny green foliage and erect stems bearing flat corymbs of small cerise-pink flowers; can spread by rhizomes.
Watch for — Flopping stems: Shade, wet, or fertile soil make stems lax; grow lean and sunny, and shear after the first flush for sturdier rebloom.
What fertiliser achillea millefolium 'cerise queen' actually wants — and why
Achillea millefolium 'Cerise Queen' 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 achillea millefolium 'cerise queen': 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 achillea millefolium 'cerise queen', 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 achillea millefolium 'cerise queen':
Light feeder needing little or no fertiliser. One light spring feed only on very poor soil. Over-feeding produces lax stems, fewer flowers, and faster spread. 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 achillea millefolium 'cerise queen' 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 achillea millefolium 'cerise queen'
Half strength is the safe default for achillea millefolium 'cerise queen' — 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 achillea millefolium 'cerise queen' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the achillea millefolium 'cerise queen' watering schedule.
Signs you are over-feeding achillea millefolium 'cerise queen'

- Lower leaves yellow and drop while the soil is correctly watered.
Signs you are under-feeding achillea millefolium 'cerise queen'
- Uniformly pale or yellow-green leaves, oldest first.

If the symptoms point at watering, light or roots rather than nutrition, the full achillea millefolium 'cerise queen' care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Flush the pot of achillea millefolium 'cerise queen' 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 achillea millefolium 'cerise queen'
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.

Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.
