African violets (Saintpaulia), with their lush green leaves and charming blossoms, are among the most popular indoor plants. Here’s a detailed guide to keeping your African violets healthy, vibrant, and blooming frequently.
About African Violets
Native to East Africa, particularly Tanzania and Kenya, African violets are admired for their compact form and colorful, velvety blooms. These plants come in a wide range of colors, petal shapes, and leaf types, from classic purple to varieties with pink, white, or even multicolored blooms. However, due to deforestation, some wild varieties are now endangered.
Choosing Your Plant
When selecting an African violet, look for dark green, blemish-free leaves and firm stems. The soil should be moist but not waterlogged. If possible, gently check the roots—healthy roots should be bright white and not overly root-bound. Buds are a good sign, as they indicate that the plant is ready to bloom.
Ideal Soil
African violets need a loose, well-draining soil mix. Choose soil specially formulated for African violets or mix perlite with potting soil to improve drainage. For best results, a blend like Espoma Organic African Violet Potting Mix with added perlite works well.
Watering Tips
Water your plant when the top inch of soil is dry. Avoid direct watering on the leaves, as they burn easily. Instead, water under the leaves or from the bottom by placing the pot in a shallow dish of water for about 30 minutes. This allows the plant to absorb moisture without risking rot.
Lighting and Temperature
African violets thrive in bright, indirect sunlight. Place them near a window with northern or eastern exposure, where they can get about 6-8 hours of light each day. Ideal daytime temperatures are between 65-75°F, and nighttime temperatures above 60°F. To add humidity, set the pot on a tray of marbles and water. Avoid placing them on cold windowsills during winter.
Fertilizer
To encourage blooming, use a specialized African violet fertilizer, such as Shultz African Violet Plus. Fertilize at a quarter strength every watering, and flush with plain water monthly to prevent salt buildup.
Blooming Tips
African violets need ample light and nutrients to bloom. Increase indirect light exposure and apply fertilizer to help stimulate blooming. If your plant hasn’t bloomed in a while, it may need more light or nutrients.
Common Problems and Pests
Overwatering is a frequent cause of root rot, so only water when the soil is dry. If leaves look pale or bleached, the plant may be receiving too much sunlight. African violets are also prone to pests like aphids, mites, and thrips. Inspect plants regularly and treat with insecticidal soap if needed, though persistent infestations may require disposal of the plant.
Repotting African Violets
African violets enjoy being slightly root-bound but may stop blooming if they become too crowded. Repot every 1-2 years using a pot with good drainage, such as a terra cotta African violet pot that offers breathability and moisture control. When repotting, disinfect pots with a bleach solution (1/3 cup bleach per gallon of water) and allow them to dry before reuse.
Propagation
Propagation is simple by leaf cuttings. Use a sterilized knife to cut a healthy leaf from the middle row of the plant, trim the stem, and plant it in a mix of potting soil and perlite. Keep the cutting moist in a mini-terrarium or a plastic bag. After 2-3 months, baby leaves should appear, and you can pot these individually when they’re large enough.
With proper care, African violets reward plant enthusiasts with vivid blooms and rich foliage, making them a delightful addition to any home.
