leaf spot disease on Snake Plant
Quick answer
If your Snake Plant has leaf spot disease, the most likely cause is: Leaf spot diseases on snake plants include fungal infections (Fusarium, Bipolaris) and bacterial infections that create distinct lesion patterns. Fungal spots typically have concentric ring patterns or dark margins, while bacterial spots are more water-soaked and lack defined margins. Both spread in moist conditions with poor air circulation.
Start here:
- 1. Isolate affected plant to prevent spread
- 2. Remove all spotted leaves at base with sterilized scissors
