Diagnose: Brown Spots on Monstera Deliciosa
Follow these steps to identify and confirm the problem.
- Root stress or a leaf lesion favored by wet conditions
- Soft dark spots with yellow borders or sticky residue support bacterial leaf spot. Yellowing that begins at an edge and turns tan then dark brown supports anthracnose, while a crisp bleached patch confined to the window-facing side supports sun scorch.
