Cold Damage on Colocasia

Commonly affects: Colocasia esculenta (Taro / Elephant Ear)

Leaves develop translucent, water-soaked, or blackened patches after cold exposure, distinct from the natural yellowing die-back of seasonal dormancy.

Potential Causes

  1. 1Exposure to temperatures below Colocasia's tropical cold tolerance, since it's native to warm, humid climates and has little frost tolerance
  2. 2Sudden unexpected cold snaps without protection for outdoor plantings
  3. 3Cold drafts affecting indoor-grown plants kept too close to a window in winter

Solution Steps

  1. 1Move container-grown Colocasia indoors or to shelter before expected frost
  2. 2Lift and store the corm for winter in climates with regular frost, rather than leaving it exposed
  3. 3Move indoor plants away from cold drafts and windows in winter
  4. 4Trim away severely damaged foliage once the danger has passed, leaving the corm to potentially resprout

Prevention Tip

Frost damage looks similar to natural dormancy die-back, but cold-damaged tissue is often blackened and mushy rather than simply yellowed and dry.
