Curling African Violet Leaves with Fuzz: Fungal Disease or Cultural Stress?

Possible Powdery Mildew

White fuzzy growth on curling leaves often indicates powdery mildew, a fungal disease favored by high humidity and poor air circulation.

Immediate Steps

1. Isolate the plant to prevent spread.
2. Improve air flow; avoid wetting foliage.
3. Apply a sulfur-based fungicide or neem oil per label directions.
4. Remove heavily affected leaves.

Alternative: Cyclamen Mites

If fuzz is on leaf undersides and new growth is distorted, cyclamen mites may be the cause. These microscopic pests require miticide treatment.

Vinegar Test (Home Remedy)

Dabbing 50/50 vinegar-water on fuzzy spots may help with mild fungal issues, but commercial fungicides are more reliable.
