Poor flowering is often related to insufficient light. African violets are highly subject to root and crown rot if overwatered. Use only warm water, as cold water causes spots on leaves. Buy only high-quality plants, because African violet pests and diseases spread very easily among other violets. Be especially watchful for crinkled tight crowns, a possible sign of incurable cyclamen mites.
Mealy bugs can also infest African violets.
Amaryllis Amaryllis are generally available from Christmas to Easter. These plants flower four to six weeks after bulbs are planted, with orange, red, white and pink varieties. Individual blooms may last three to four days. In later summer or fall, as the leaves begin to die back, water less often. Azalea Most azaleas bought from florists, supermarkets and other flower shops are special varieties developed for the greenhouse.
