Causes of Brown Spots on African Violet Leaves with solution?
Brown spots on African violet leaves can be caused by several factors. Here are some common causes and solutions:
- Overwatering:
- Symptoms: Brown spots, especially on the lower leaves.
- Solution: Allow the soil to dry out slightly between waterings. Ensure the pot has good drainage.
- Underwatering:
- Symptoms: Dry, crispy brown spots, often on the edges of leaves.
- Solution: Water your African violet regularly, ensuring the soil is consistently moist but not soggy.

- Solution: Increase humidity by misting the plant regularly, using a humidifier, or placing the pot on a tray of pebbles filled with water.
- Nutrient Deficiency or Toxicity:
- Symptoms: Brown spots, yellowing leaves, or stunted growth.
- Solution: Fertilize your African violet with a balanced, water-soluble fertilizer diluted to half strength. Avoid overfertilizing.
- Pests and Diseases:

- Solution: Move your African violet to a location with bright, indirect light. Avoid direct sunlight.
Additional Tips:
