Commercially prepared packaged soil mixtures are available for African violets. Clay or plastic containers are both satisfactory, but the type of container has an important effect on the frequency of watering. Clay pots require more frequent watering than plastic since the amount of evaporation is greater. Decorative glazed pots without drainage holes should not be used due to the lack of drainage. Sterilized soil and containers are important.
African violets are very susceptible to crown and root rots.
They may be watered from the top or bottom. When watering from the top, apply enough water to thoroughly saturate the soil. Allow excess water to drain from the bottom of the container. Cold water that comes in contact with the leaves of African violets can cause white blotches. To water the plant from below, place the container in a tray containing about 1 inch of water.
