Over-watering is the most common reason for unsuccessful growing of African violets. If violets just don't thrive with you, it's probably because of over-watering. If you're able to keep them alive but can't get them to bloom, insufficient ligthing might be the issue. There are many methods for watering African violets. Which ever method you choose, try to maintain an adequately moist soil. Not soggy. Keep the crown dry, keep cold water off the leaves, and use room temperature water. Watering from the top is the easiest way to give your plants the moisture they need. Apply water to the surface of the soil when dry to the touch. To water from the bottom, fill the saucer under the pot with water and let stand until the soil surface becomes moist, then drain off any excess water. Do not let plant sit in water for more than 30 minutes.
