About Lantana

Lantana camara · also called Lantana, Common lantana · flowering

Lantana camara is a heat-loving flowering shrub prized for clustered, colour-shifting blooms that draw butterflies all season. It thrives in full sun with well-drained soil and minimal water once established. The ASPCA lists it as toxic to dogs, cats, and horses, so keep pets and grazing animals away from the foliage and berries.

Mature size: Typically 1-1.5 m (3-5 ft) tall and wide under glass or in cooler climates; can reach 1.8 m or more as a mature shrub in frost-free regions. Trailing types stay lower and spread.

Watch for — Few or no flowers: Almost always too little light. Lantana needs full direct sun to bloom well; move it to the sunniest spot and avoid excess nitrogen fertiliser, which favours foliage over flowers.

How to tell lantana needs repotting

Repotting on a calendar is less reliable than reading the plant. For lantana, 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 lantana

Pot on seedlings as they grow; not a perennial repot. Lantanais grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Fast-growing, mounding to sprawling evergreen shrub with arching stems and dense clusters of small tubular flowers that often shift colour as they age. Frequently grown as a perennial in warm zones or as an annual or container plant elsewhere; trailing cultivars suit hanging baskets..

What size pot to step lantana up to

Pot lantana 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 lantana

Pot lantana 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 lantana

  1. Pot on before it is root-bound. Check lantana 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 fertile, moist but well-drained soil 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 lantana 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 lantana

Lantana wants fertile, moist but well-drained soil. Adaptable to chalk, clay, loam, or sand at any pH, but sharp drainage is essential. In containers, use a loam-based mix amended with perlite or grit. Heavy, poorly draining soil leads to root rot and weak flowering. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting lantana — frequently asked questions

How often should you repot lantana?

Pot on seedlings as they grow; not a perennial repot for lantana. Lantana is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into fertile, moist but well-drained 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 lantana need?

Pot lantana 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 lantana?

Pot lantana 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 lantana straight into a much bigger pot?

No. Even a fast-growing lantana 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 lantana after repotting?

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