Saving a Sunburned Houseplant: Immediate Steps

Leaves that turn dark, shriveled, and smell off after intense sun exposure are sunburned—they won't recover. Remove them promptly to prevent rot. The unaffected side of the plant will generate new growth.

Watering After Heat Stress

Extra water won't fix sunburn. Only water when the top 1–2 inches of soil are dry. Use distilled or rainwater to avoid fluoride/chlorine damage. Ensure the pot drains freely and never sits in a water-filled saucer.

Prevention

• Acclimate plants gradually to brighter light.
• Use sheer curtains or move plants back from hot windows.
• Monitor car interiors—never leave plants in parked vehicles.
