When & how to repot Chamomile (Matricaria chamomilla)

Also called German chamomile, wild chamomile, Hungarian chamomile.

About Chamomile

Matricaria chamomilla · also called German chamomile, wild chamomile · flowering

German chamomile is a self-seeding annual herb with feathery foliage and small daisy-like flowers used in herbal teas. Roman chamomile (Chamaemelum nobile) is a closely related perennial used for fragrant lawns. Both thrive in sun and free-draining soil. Mildly toxic to pets in quantity.

Matricaria chamomilla (German chamomile) is an annual in the daisy family native to southern and eastern Europe and western Asia, naturalized in disturbed meadows and fields.

Not fussy about soil and thrives in average, dry, well-drained ground; the most aromatic, high-oil plants come from relatively lean soil.

Mature size: 40-60 cm tall

How to tell chamomile needs repotting

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

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 chamomile

Pot on seedlings as they grow; not a perennial repot. Chamomileis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Upright self-seeding annual.

What size pot to step chamomile up to

Pot 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 chamomile

Pot 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 chamomile

  1. Pot on before it is root-bound. Check chamomile regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
  2. 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.
  3. 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.
  4. Pot into rich mix. Set it into fresh free-draining loam at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
  5. Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water 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 chamomile

Chamomile wants free-draining loam. pH 5.5-7.5. Tolerates poor soil. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting chamomile — frequently asked questions

How often should you repot chamomile?

Pot on seedlings as they grow; not a perennial repot for chamomile. Chamomile is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into free-draining loam 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 chamomile need?

Pot 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. Use our pot size calculator to size it from the plant's current pot and root spread.

When is the best time of year to repot chamomile?

Pot 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.

Can you put chamomile straight into a much bigger pot?

No. Even a fast-growing 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 chamomile after repotting?

Not immediately. Wait about 1 week after repotting 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.
