The fig fruit is an inverted flower with both the male and female flower parts enclosed in stem tissue. This structure is known botanically as a syconium. At maturity the interior of the fig contains only the remains of these flower structures, including the small gritty structures commonly called seeds. Actually, these so-called seeds usually are nothing more than unfertilized ovaries that failed to develop. They impart the resin-like flavor associated with figs.
Plentiful sunlight is a key to maximizing fruit production.
Choose an area that is in the sun most or all of the day. Otherwise, expect reduced performance from the trees. Good drainage is a more important consideration than soil fertility. Avoid soils and sites where water stands for more than 24 hours after a rain. In areas of poor drainage, roots receive insufficient oxygen and will die, resulting in stunted growth and eventual death of the tree.
