The accumulation of salts can ultimately damage or destroy foliage. Flush soils occasionally with clear water to eliminate salt buildup in the soil. Peat-based soils that have been pasteurized are best. Garden or field soil is not satisfactory alone since it is often poorly drained and compacts easily. Many commercial soiless mixes are available.
African violets make great houseplants.
With a proper environment and regular care they will reward you with blooms all year. If grown properly, African violets have few problems with insects or diseases. Some of the more common pest problems include mites and mealybugs. Mites are small spiders that attack the undersides of the leaves, new growth, and flowers. Mites are so small they are not visible to the naked eye and the damage to the plant is often noticed first.
