How to Grow and Care
African Violets will thrive in bright, warm and humid conditions. Keep water from touching their leaves or it will leave brown spots. Remove dead flowers and leaves as soon as you seen them to encourage a healthier plant. Regularly check the soil and plant to make sure there is no accumulation of dead leaves. This will encourage rot.
Growing these houseplants is really a matter of balance. You have to make sure that the different factors that go into their cultivation all are weighted against each other. They should be kept in moist enough conditions that they don't dry out, yet still exposed to a fresh breeze to avoid letting them get too stuffy, and exposed to sunlight without damaging their leaf tips. Don't be discouraged if your African Violets suffer some damage. It is all part of the process.
African Violets do better when they are slightly underpotted. Repot only when necessary into a pot that is one size up. To repot these plants, simply grab the plant as a whole, lift it, and replace it into a larger container, making sure not to damage their root systems in the process… – See more at: How to Grow and Care for African Violets
