🔍 Possible Causes (4)
Leaf Spot
Leaf spot is a common fungal disease caused by various pathogens including Alternaria, Ascochyta, Colletotrichum, Septoria, and Venturia. It primarily affects leaves, causing discolored spots that can lead to premature leaf drop if left untreated.
✓ Related symptoms:
- • Circular brown, gray, black, or yellow spots on leaves
- • Yellow halo surrounding spots
⚡ Quick Fixes:
Remove all visibly infected leaves
Overwatering
Overwatering occurs when plants receive too much water, depriving roots of oxygen and causing root rot. This environmental stress is one of the most common causes of houseplant death, as waterlogged soil prevents roots from breathing and functioning properly.
✓ Related symptoms:
- • Yellow or brown limp, droopy leaves that feel soft and mushy
- • Dropping leaves (both old and new) that may be green, brown, or yellow
- • Brown spots or edges with yellow halos on leaves (bacterial infection)

Crown Rot
Crown rot is a serious fungal disease that attacks the crown (base) of the plant where the stem meets the soil. It is caused by various fungal pathogens including Phytophthora, Fusarium, and Rhizoctonia. The disease thrives in waterlogged conditions and can quickly spread to kill the entire plant if not addressed promptly.

- • Yellowing of lower leaves that drop prematurely
⚡ Quick Fixes:
Immediate unpotting
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
