Fruit Drop (physiological - flower development): The fig produces four types of flowers (male, female, Gall, and Mule): The male and female flowers are most often associated with the Capri type fig. This fig requires a wasp for pollination. The wasp does not occur in this part of the United States, thus it is impossible to grow Capri figs in Texas. Gall flowers are imperfect female flowers. They are found only on Capri and Cordelia figs. Mule flowers need no pollination and produce no seeds. The common fig grown in Texas produces primarily mule flowers. Since no seed are formed, the mule flowers are more subject to dropping than than those flowers which require pollination. The presence of the seed and the growth hormones produced by the seed help prevent fruit drop. The figs grown in Texas due to absence of seed are more subject to premature fruit drop as a result of adverse growing conditions. See also Fig Diseases in North Carolina (NCSU).
