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.
Fertilize young Meyer lemon trees after they have been in the ground at least two years, which is when they begin to demand heavy nitrogen. Feed 2-year-old trees 1/3 cup of 21-0-0 ammonium sulfate in January or February as soon as new growth emerges. Broadcast the fertilizer from the trunk to the drip line.
