Fertilize citrus: Trees up to 4 years old should be fertilized four to six times a year, from January through October. Do not use a fertilizer with an analysis higher than 8-8-8. Apply 1 pound of fertilizer per year of the tree's age per application.
For mature, fruit-bearing trees older than 4 years, apply fertilizer in January-February, May-June and October-November. Apply 1 pound of fertilizer per year of the tree's age up to a maximum of 10 pounds per application. Use an 8-8-8 fertilizer containing secondary nutrients (particularly magnesium, manganese, copper and boron). Fertilize an area twice the diameter of the tree canopy.
