Water - Not Enough
While it is often said that underwatering is better than overwatering, do not overdo it. Paradoxically, underwatering can contribute to the same problems as overwatering, i.e., Crown Rot, Pythium and Root Rot. This is especially the case since underwatering, over time, will reduce a Violet's resistance to disease.
If your African Violet has this symptom, it is probably not getting enough water.
Increase frequency of watering. Soil should always be moist, but not soggy. To help maintain a healthy watering schedule, you may want to try using a self-watering device, such as the Optimara WaterShip, MaxiWell, MiniWell or Watermaid.
Always keep soil moist, but not soggy. Try using a self-watering device, such as the Optimara WaterShip, MaxiWell, MiniWell or Watermaid. These devices maintain a consistent amount of moisture in the soil and eliminate any danger of either underwatering or overwatering.
If you are having trouble keeping the soil moist, it may be that the air temperature is too warm. While African Violets will tolerate temperatures from 60 to 80 degrees F, they prefer a temperature that is about 70 degrees. With each increase of 10 degrees over this, the rate of evaporation from the leaves increases by 50 percent. Also, make sure your African Violets are getting the proper humidity. Low humidity will also increase the rate of evaporation.
