I have a African Violet that is in one of those pots where you pour water into the bottom container and the potted plant sits in the bottom container of water and soaks up the water through the clay pot. This plant has not bloomed in probably over a year. What is the best way to fertilize a plant like this and what kind of fertilizer would someone recommend?

African Violets need to dry out completely between waterings. The moist soil is one reason that your plant will not bloom. They also like to have lower temperatures at night.

What is the best soil to use for African Violets? I need to add some but I do not know what soil I should use.

I agree with Rita that AV's like to dry out. Small containers of AV fertilizer and AV soil are available at the box stores and nurseries. I like to fertilize often with very dilute weak fertilizer. Your plant may need a little more light........welcome to ATP.
