Grow African violets by providing the correct temperature and lighting conditions, watering and fertilizing them when necessary, and repotting them annually. Propagate them with leaf cuttings.Continue Reading
Keep the room temperature between 65 and 80 degrees Fahrenheit to ensure the health of your African violets. Growth slows and leaves darken at temperatures under 65 degrees, and leaves may become injured and flower growth impeded at temperatures above 85 degrees.
Give African violets plenty of light, but it should not be too hot or direct. Dark, overly-thin leaves are a sign of insufficient light. Small, pale, crinkled leaves indicate too much light.
Water African violets when the top of the soil is dry. Use lukewarm water instead of cold. When watering from the top, avoid wetting the leaves to prevent leaf spot. Alternatively, fill a saucer below the plant so the soil absorbs the water from underneath.
Fertilize the plants regularly with special African violet fertilizer or a diluted 20-20-20 fertilizer. The amount needed depends on the soil mixture. Soilless potting mix needs frequent fertilization.
Repot African violets every six months to a year. Since the plants must be pot-bound to blossom, use pots that are one-third the width of the plant.
Create new African violet plants by cutting whole, healthy leaves with stems, planting them in growing medium and watering them regularly.
