leaf spots on Rubber Plant
Quick answer
If your Rubber Plant has leaf spots, the most likely cause is: Small, water-soaked lesions that expand into angular brown spots with yellow halos indicate bacterial leaf spot, typically caused by Pseudomonas species. Unlike fungal spots (which have concentric rings), bacterial lesions follow leaf veins creating angular patterns. Infection enters through wounds or natural openings, spreading rapidly in high humidity with poor air circulation. Overhead watering and splashing soil are primary transmission vectors.
Start here:
- 1. Remove and destroy severely affected leaves—do not compost
- 2. Avoid overhead watering; water at soil level only
