Trees growing in tropical climates grow blossoms and yield fruit off and on all year. The yield timing is different for trees growing in Mediterranean climates. More than 300 hours of accumulated temperature below 68 degrees Fahrenheit induces flowering and fruit production. This is called the chill factor. Large numbers of citrus flowers drop from the tree after they open, and an equally large number of young fruits drop from the tree.
