brown spots on Syngonium
Quick answer
If your Syngonium has brown spots, the most likely cause is: Sudden exposure to direct sunlight or intense afternoon rays (especially from west-facing windows) on shade-adapted Syngonium foliage. This triggers phototoxicity, breaking down chlorophyll and causing localized tissue death which manifests as crispy brown spots, often with yellow halos.
Start here:
- 1. Relocate the plant to a spot with bright indirect light (1000-3000 lux).
- 2. Install sheer curtains or blinds to diffuse incoming direct sunlight.
