brown spots on Ficus
Quick answer
If your Ficus has brown spots, the most likely cause is: Brown spots on Ficus leaves typically result from inconsistent watering (either over or underwatering), low humidity causing desiccation, or bacterial/fungal infection (often Xanthomonas or Pseudomonas). Inconsistent moisture causes leaf cells to die in patches, while pathogens cause water-soaked spots that turn brown and may have yellow halos.
Start here:
- 1. 1. Inspect leaves closely: bacterial spots have yellow halos and spread rapidly; fungal spots are dry and may have concentric rings.
- 2. 2. Remove affected leaves immediately to prevent spread. Sterilize pruning tools between cuts.
