If, on the whole, your plant looks healthy but has simply stopped blooming, it may be getting less light than it once did. Remember, the light entering windows can change as trees grow or as structures are added to your landscape. Try moving the plant to a brighter location. Low temperatures also inhibit flowering in African violets. If none of these situations seems to apply, repot the violet in fresh soil, using a slightly larger pot. It could also be that the plant has outgrown its container. You'll know that this is the case if the top of the plant extends far beyond the rim of the pot, or the pot has a tendency to tip over. Remember, too, that plants need food to flower. Give your plant some liquid fertilizer developed for African violets. If the new leaves are curled or disfigured in any way, the plant may have cyclamen mites. Take a few sample leaves to a local garden center and ask for treatment suggestions.
