For as pretty as they look in the garden centers, many people bring them home never to see another bloom. It can be one or a combination of several reasons. It is suggested that the most ideal temperature for African Violets is between 62 and 78 degrees. If the temperature is considerably lower than 62 for several days, the plant will suffer, and likewise, if the temperatures climb above 80 for several days, the plant will become stressed and cease to thrive. Luckily for the home gardener, most home environments fall comfortably in-between these two temperatures, which is perfectly suitable for nurturing proper violet growth.
African violets seem to do best in a simple, peat based compost or potting soil.
It is advised to repot if and when your violet becomes overly rooted to its medium, as the plant will not grow well if bound or if the medium has been allowed to harden. It has been argued that watering is the key to violet success. There are two ways to water, the most favored being watering from the bottom by emerging the pot in standing water until it is absorbed and the soil is damp to the touch. Contrary to popular belief, you CAN water violets from the top, but you have to be sure not to splash water on the leaves, or soak the crown of the plant. Either method is suitable.
