Fertilize citrus trees in the spring and summer. The ability of a citrus tree to use nutrients in fertilizer depends largely on whether or not it is growing in the proper soil. Citrus trees most often need nitrogen, although they may also be deficient in minor nutrients.
When to fertilize. To get your plants off to a good start, fertilize when the spring growing season begins. Many gardeners use a general-purpose fertilizer at this time (either an evenly balanced formulation or one slightly higher in nitrogen); others add only nitrogen. How often you fertilize later in the year depends on the plant.
