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.
To maintain healthy trees, fertilize citrus every six weeks when the tree is under seven years old with a good citrus fertilizer, not fertilizer tree spikes. Adult trees should be fertilized often but in small amounts. Fertilize from October through February.hen roots of the tree sit in water, they have a tendency to develop root rot, which in turn results in the lemon tree dropping leaves. Mulch around the root area, minimize irrigation, plant in well draining soil and keep grass away from the base of the tree to avoid root rot and its accompanying problems.
