Many gardeners successfully grow figs (Ficus carica) in New Jersey for many years. However, since fig trees are evergreen plants in warmer climates. some type of low temperature protection is needed. Figs thrive in areas where winter temperatures do not drop below 15° F. Young trees can be damaged by early fall frosts when the temperature is 25-27° F. In New Jersey, fig trees will lose their leaves at this time and must be prepared for
the dormant season’s low temperatures to survive and flourish. One problem in New Jersey is that a fall frost often kills the second or late season figs before they fully mature. In the late winter, fig trees will begin their regrowth early and need continued protection until the temperatures moderate and danger of spring frosts has passed.
