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.

Mature size: Around 5-10 cm tall, each plant spreading 15-25 cm; planted in a grid it knits into a continuous lawn.

Watch for — Bare patches in shade or wet: The mat thins and dies out in shaded or poorly drained spots; site it in full sun on free-draining soil and patch gaps with fresh divisions.

How to tell treneague chamomile needs repotting

Repotting on a calendar is less reliable than reading the plant. For treneague chamomile, watch for these signs:

Roots circling the bottom of the module or pot, or poking out of the drainage holes.
The seedling dries out within a day and growth has visibly stalled.
Roots are white and matted in a tight spiral when you tip the plant out.
It has outgrown its current container for the stage of the season — pot treneague chamomile on before it becomes hard root-bound.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot treneague chamomile

Pot on seedlings as they grow; not a perennial repot. Treneague Chamomileis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Low, mat-forming evergreen perennial spreading by creeping, rooting stems; non-flowering, so it stays neat and low without mowing..

What size pot to step treneague chamomile up to

Pot treneague chamomile on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot treneague chamomile

Pot treneague chamomile on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Step-by-step: repotting treneague chamomile

Pot on before it is root-bound. Check treneague chamomile regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
Step up one or two sizes. Choose the next container up — not a giant one. Cold, wet, unused soil around a small root system stalls seedlings.
Knock it out gently. Support the stem, tip the pot, and ease the rootball out without breaking it. A little teasing of circled roots at the base is fine.
Pot into rich mix. Set it into fresh light, free-draining sandy or loamy soil at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water treneague chamomile in well and keep it in bright light; a freshly potted-on seedling can wilt for a day while roots settle, so do not overcompensate by drowning it. Do not fertilise for about 1 week — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for treneague chamomile

Treneague Chamomile wants light, free-draining sandy or loamy soil. Demands sharp drainage; waterlogged or heavy clay soil causes rot and bare patches. A neutral to slightly acidic, low-fertility soil gives the best dense, springy growth. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting treneague chamomile — frequently asked questions

How often should you repot treneague chamomile?

Pot on seedlings as they grow; not a perennial repot for treneague chamomile. Treneague Chamomile is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into light, free-draining sandy or loamy soil so the roots never circle the cell, ending in a large final container. A root-bound transplant stalls and never fully recovers.

What size pot does treneague chamomile need?

When is the best time of year to repot treneague chamomile?

Can you put treneague chamomile straight into a much bigger pot?

No. Even a fast-growing treneague chamomile should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise treneague chamomile after repotting?

Not immediately. Wait about 1 week after repotting treneague chamomile. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
