Everything it needs
9 essentials at a glance
Watering
Water African Violets when the top inch of soil feels dry, typically every 5-7 days.
Use room temperature water and avoid getting water on the leaves to prevent spots. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and drooping leaves.
Light
African Violets thrive in bright, indirect light.
Ideally, they should receive 10-12 hours of light daily, placed near a window with filtered sunlight. They can tolerate some direct morning sun but avoid harsh afternoon rays, which can scorch the leaves.
Soil
A well-draining potting mix is essential, ideally with a pH of 6.0 to 6.5.
A mix of peat moss, perlite, and vermiculite works well. Ensure the pot has drainage holes to prevent water accumulation, which can lead to root rot.
Humidity
African Violets prefer humidity levels of 40-60%.
To increase humidity, place a tray of water with pebbles beneath the pot or use a humidifier. Signs of low humidity include browning leaf edges and wilting flowers.
Temperature
Ideal temperatures range from 65-75°F (18-24°C).
They can tolerate temperatures as low as 60°F (15°C) and as high as 80°F (27°C) but should be protected from drafts and sudden temperature changes. They thrive in USDA hardiness zones 11-12.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 14-12-14, applying every 4-6 weeks during the growing season.
Reduce feeding in fall and winter. Signs of nutrient deficiency include stunted growth and pale leaves.
Pruning
Prune African Violets to remove dead or yellowing leaves and spent flowers.
Use clean, sharp scissors to avoid damaging the plant. Regular deadheading encourages new blooms and maintains a tidy appearance.
Repotting
Repot every 1-2 years or when the plant outgrows its pot, indicated by roots growing through the drainage holes.
Choose a pot 1-2 inches larger in diameter. Gently remove the plant from its pot, trim any dead roots, and place it in fresh potting mix, ensuring the crown is above the soil level.
Propagation
Propagation can be done through leaf cuttings.
Cut a healthy leaf with a stem about 2-3 inches long, place it in a glass of water or directly in moist potting mix, and cover it with a plastic bag to maintain humidity. Roots will develop in 4-6 weeks. The best time to propagate is during the growing season in spring or summer.
When it's unhappy
Yellow leaves
Why it happens
Often caused by over-watering or insufficient light.
How to fix it
Reduce watering frequency and ensure the plant receives adequate light.
Brown leaf edges
Why it happens
Indicates low humidity or exposure to cold drafts.
How to fix it
Increase humidity around the plant and keep it away from cold air.
Wilting flowers
Why it happens
Can result from under-watering or too much direct sunlight.
How to fix it
Adjust watering schedule and move the plant to a location with indirect light.
Root rot
Why it happens
Caused by over-watering and poor drainage.
How to fix it
Allow the soil to dry out and repot in fresh, well-draining mix if necessary.
Leaf spots
Why it happens
Often due to water on the leaves or fungal infections.
How to fix it
Water at the base of the plant and ensure good air circulation.
Care through the year
Spring
In spring, increase watering frequency as the plant begins to grow actively. Fertilize every 4-6 weeks to support new growth and blooming.
Summer
During summer, ensure the plant receives adequate light but avoid direct afternoon sun. Maintain humidity levels and water regularly to prevent drying out.
Fall
In fall, reduce fertilization as growth slows down. Monitor watering closely, as the plant may require less water with cooler temperatures.
Winter
In winter, keep the plant in a warm area away from drafts. Water less frequently and avoid fertilizing until spring, as the plant enters dormancy.
Toxicity & Safety
African Violets are non-toxic to pets and children. However, ingestion of large quantities may cause mild gastrointestinal upset.
