Excess light / sunburn
Unacclimated tissue can bleach or scorch after intense exposure.
WatchPossible cause—not a diagnosis. Compare the visible signs, plant identity, and growing conditions before treating.
Signs you may notice
- bleached patches
- crispy patches
- exposed leaves
- sudden damage
Safe first checks
- Check whether damage is concentrated on the most exposed side and followed a recent move.
- Photograph the affected area in clear natural light.
- Review recent changes in light, temperature, water, feeding, or location.
- Change one likely cause at a time and record the result.

- spray burn
- fertilizer burn
What to avoid
Do not make several care changes at once; that makes the response harder to interpret.
Record and follow up
Photograph the same area again and record one change at a time. Compare new growth and whether the symptom spreads, stabilizes, or improves.
Seek qualified local help when damage is severe, rapidly spreading, or may involve a regulated pest or disease.
