Temperature: African violets prefer temperatures between 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) for short periods of time, but prolonged exposure to extreme temperatures can harm the plant. Humidity: African violets prefer moderate humidity levels around 50-60%. If the air in your home is dry, you can increase humidity by placing a tray with pebbles and water under the plant, keeping it away from direct sunlight so the water will not evaporate too quickly. Alternatively, you can use a humidifier or mist the leaves of the plant with water daily. Avoid getting water on the leaves if you can, as it can cause spotting or encourage mold growth.
