Sunburn on Orchid Leaves

Commonly affects: Phalaenopsis spp. and other Orchidaceae (Orchid)

A bleached, yellow-white, or brown patch develops on the leaf, usually on the side that received direct sun exposure, and doesn't recover once damaged.

Potential Causes

  1. 1Direct sun exposure, which most orchids (especially Phalaenopsis) cannot tolerate
  2. 2Sudden move from a shadier spot to a brighter, sunnier window without acclimation
  3. 3Sun intensifying through a window at certain times of day or year

Solution Steps

  1. 1Move the plant to bright, indirect light rather than direct sun
  2. 2Use a sheer curtain to filter direct sun if a bright window is the only available spot
  3. 3Damaged leaf tissue won't recover, but new growth will be unaffected once the plant is moved
  4. 4Acclimate gradually if you do want to introduce more light, watching closely for stress signs

Prevention Tip

Most common orchids are naturally adapted to filtered forest-canopy light — direct sun is one of the most common and avoidable causes of leaf damage.
