Foliage: Violet
Light
Bright, but not direct sunlight. They are commonly grown under fluorescent lights placed 12 to 15 inches above the leaves.
Soil
A well-drained potting mix is essential. Poor drainage can cause root rot, in which the plant becomes waterlogged and its leaves begin to fall, so make sure that the plant is never allowed to be exposed to standing water for an extended period of time.
Water
Keep soil moist with warm water and strive for high humidity. Do not allow water to contact the leaves to prevent damage, other than light misting. Water from below, or push the water spout into the soil when watering. Don't allow the plant to sit in water.
Temperature and Humidity
Do not allow to fall below about 60ºF. They thrive at 70ºF.
Fertilizer
Feed with an African violet fertilizer every other week.
