Phalaenopsis Sunburn Recovery: Light Requirements and Repotting Priority

Diagnosing Sun Damage

Yellow/purple spotting on leaves after moving to hot, sunny conditions = sunburn. The largest, oldest leaf shows worst damage. Halogen desk lamps can also generate leaf-burning heat.

Ideal Light Conditions

Phalaenopsis thrive in east windows with morning sun. Avoid direct afternoon sun and hot artificial lights close to foliage.

Immediate Action: Check Roots First

Before the new spike develops further, unpot and inspect roots. If not recently repotted, remove old mix, trim mushy roots, and repot in fresh orchid mix. Annual repotting supports the energy demands of blooming.
