About Treneague Chamomile
Chamaemelum nobile 'Treneague' · also called Treneague chamomile, non-flowering chamomile · herb
'Treneague' is a low, non-flowering clone of Roman chamomile grown chiefly for fragrant chamomile lawns and seats. Its dense, apple-scented evergreen mat releases scent when walked on and never needs mowing since it rarely flowers. Spreading by creeping stems, it suits sunny, free-draining sites and is propagated only by division, as it sets no seed.
Growth habit: Low, mat-forming evergreen perennial spreading by creeping, rooting stems; non-flowering, so it stays neat and low without mowing.
What fertiliser treneague chamomile actually wants — and why
Treneague Chamomile is a soft, fast leafy herb that you harvest hard — a modest balanced feed keeps tender growth coming without tipping it into bland or bolting.
A balanced general feed (even N-P-K) at modest strength — enough nitrogen to keep replacing the leaves you pick, but not so much that flavour thins or it bolts to seed.
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 treneague chamomile: 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 treneague chamomile, 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 treneague chamomile:
Feed sparingly or not at all; lush growth from rich soil or fertiliser is weak and opens the mat to weeds. An occasional light, balanced feed in spring is the most it needs. In practice: a balanced liquid feed every few weeks through the main growing and harvesting season (spring through early autumn), more often the harder you are picking it.
The dormant-season rule matters more than the exact interval: skip feeding entirely when treneague chamomile 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 treneague chamomile
Half strength is a sensible default for treneague chamomile — enough to fuel regrowth after cutting, gentle enough that the leaves stay aromatic rather than watery.
Feeding always goes onto already-damp soil, never dry roots — water treneague chamomile first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the treneague chamomile watering schedule.
Signs you are over-feeding treneague chamomile
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for treneague chamomile:
- Fast, soft, pale growth with diluted, less aromatic flavour.
- Early bolting (running to flower) and a bitter edge.
- Salt crust and scorched tips on container plants.
Signs you are under-feeding treneague chamomile
- Pale, slow regrowth after cutting and small leaves.
- A tired, stalled plant that cannot keep up with harvesting.
- Yellowing older leaves in a long-spent pot.
If the symptoms point at watering, light or roots rather than nutrition, the full treneague chamomile care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
Pot-grown treneague chamomile builds up feed salts quickly — water until it drains each time and flush the pot with plain water every few weeks, especially on a sunny windowsill.
Organic vs synthetic feeds for treneague chamomile
Organic options
A diluted seaweed feed or worm-casting tea keeps soft growth coming without overdoing it. UK: dilute seaweed or Westland; US: Espoma Garden-tone or Neptune's Harvest. Gentle, hard to overdo, flavour-friendly.
Synthetic / liquid feeds
A balanced liquid feed at half strength through harvesting — UK: Phostrogen, Baby Bio or Westland; US: Miracle-Gro all-purpose at half strength. Fast regrowth; just do not overdo the nitrogen.
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 treneague chamomile look like?
Fast, soft, pale growth with diluted, less aromatic flavour. Early bolting (running to flower) and a bitter edge. Salt crust and scorched tips on container plants. Over-feeding treneague chamomile with strong nitrogen is the usual mistake — it grows fast and lush but the leaves turn bland and it bolts to flower sooner, ending the useful harvest early.
Should I flush the soil of treneague chamomile?
Pot-grown treneague chamomile builds up feed salts quickly — water until it drains each time and flush the pot with plain water every few weeks, especially on a sunny windowsill.
