Sunburn on Colocasia Leaves

Commonly affects: Colocasia esculenta (Taro / Elephant Ear)

A bleached, yellow-white, or brown patch develops on the leaf, usually on the side facing intense, direct midday sun, especially in varieties that prefer some shade.

Potential Causes

  1. 1Direct, intense midday sun exceeding what the specific variety tolerates, since some Colocasia cultivars prefer partial shade while others tolerate more sun
  2. 2A sudden move from a shadier spot to intense direct sun without acclimation
  3. 3Particularly intense heatwave conditions even for a sun-tolerant variety

Solution Steps

  1. 1Provide light afternoon shade, especially for varieties known to prefer some shade or in regions with intense summer sun
  2. 2Acclimate gradually when moving a plant to a sunnier spot, over 1-2 weeks
  3. 3Damaged leaf tissue won't recover, but new growth will be unaffected once conditions are adjusted
  4. 4Research your specific variety's sun tolerance, since this varies noticeably across Colocasia cultivars

Prevention Tip

Sun tolerance varies significantly between Colocasia varieties — check your specific cultivar's preference rather than assuming all varieties handle full sun equally.
