Brown, Wilted Leaf Edges on African Violet: Diagnosing the Cause

Your African violet is flowering and the stems look healthy, but leaf edges—even on new center growth—are turning brown-black and wilting. The soil moisture seems correct. What's going on?

This symptom is contradictory: brown, dry edges typically indicate underwatering or low humidity, while center leaf involvement suggests overwatering or crown rot. Since you're confident in your watering, a sudden-onset issue like a pest or disease is likely.

Key Diagnostic Questions

• Are the affected edges dry and crispy or soft and mushy?
• Any tiny insects, webbing, or sticky residue on leaf undersides?
• White powdery coating on soil surface or root ball?
• Recent changes in temperature, drafts, or water source?

Likely Culprits

Cyclamen mites cause distorted, darkened new growth and brittle leaf edges—often before flowers are affected. Thrips leave silvery patches and black fecal dots. Root mealybugs (soil mealybugs) show as white powder on roots and cause wilting despite moist soil. Fungal leaf spot (e.g., Botrytis, Phyllosticta) creates dark, sometimes mushy margins.

For a definitive diagnosis, a clear close-up photo of the affected leaves (top and bottom) and the root ball is invaluable. In the meantime, isolate the plant, avoid wetting foliage, and ensure good air circulation. If roots are white and firm, a targeted miticide/insecticide or fungicide may be warranted based on the identified pest.

Don't guess—accurate identification saves the plant and prevents spread to your collection.
