How to Propagate Elephant Ear

Alocasia / Colocasia spp.

Methods Division (offsets/corms)
Difficulty Intermediate
Best season Spring–summer
Time to root 3–5 weeks
Group Houseplant

Elephant ear grows from underground corms that naturally produce offset corms alongside the main one. Separating these offset corms is the only reliable propagation method — leaves alone have no capacity to grow roots.

Division (corms)

  1. Remove the plant from its pot or dig it up.
  2. Find smaller offset corms attached to or near the main corm.
  3. Separate them by hand or with a clean cut.
  4. Let cut surfaces dry a day if separated with a knife.
  5. Pot in moist, well-draining mix.

When to propagate

Spring through summer, during active growth.

Common problems

Corm rotted after potting. Too wet — let the mix dry between waterings until new growth is established.

Questions people ask

Is it toxic? Yes, toxic if eaten — contains calcium oxalate crystals like many aroids.
