According to the African Violet Society, plastic pots are preferred by growers. Clay pots allow too much evaporation adn the soil will go dry at the top, probably because the moisture is evaporating out the sides. Select pots which were designed with rolled edges. That said, there are times when a clay pot is desirable— most especially in hot climates or greenhouse growing. The evaporation from the clay works as a cooling device and actually keeps the roots cooler. Since many growers are in climate-controlled environments, this feature seems to be less important these days.
