How much light is needed for fruit production?
Blooming and fruiting is dependent on adequate light and heat. Citrus trees in a dark or shaded space will produce lots of foliage but may not flower. If you do not have a bright window, skylight or greenhouse, you may want to supplement with grow lights. For best results indoors, simulate California weather by providing a minimum of 6 hours of direct light each day. Grow lights can be used in addition to sunlight and should not be left on longer than the daylight hours.
