Violets will flower more often if you use fertilizer. This is much like how we take vitamins - we don't absolutely need them but they do help us overall. We recommend using the brand 'Peter's for Violets' and you can pick this up at most locations that sell plants. Mix 1/4 teaspoon to a gallon of water. We suggest using a gallon water jug, store it under your sink and just use that each time you fill the water in the pot!
