Fertilization Violets, like most plants, respond well to regular doses of fertilizer. Dry fertilizers and slow-release or encapsulated fertilizers can also be used. With a dry fertilizer, be sure the soil is moist before you use it. Regardless of which kind of fertilizer you use, read and follow the manufacturer's recommendations. Plants in less than ideal conditions or in non-active stages of growth may require less fertilizer.
African violets are very sensitive to a build-up of soluble salt which can damage plant roots.
Note, too, that excess fertilizer can result in symptoms that sometimes mimic deficiencies. A soil test will be your best guide in figuring out the problem. Propagation Violets can be propagated through leaf cuttings. African violets can be grown from seed, but only a few varieties will come true. A flowering plant can be produced from a leaf cutting or a seed in about 10 months under good growing conditions.
