Citrus

One of the satisfactions that nearly all homeowners in Florida can have is to pick citrus fruits from their own trees.  However, the varieties that may be grown vary with the climatic conditions of each location.  Citrus is a subtropical fruit tree and is limited to areas that do not regularly experience freezing temperatures, although a few types will tolerate freezing temperatures in north Florida.  Careful consideration should be given to site selection, choice of variety, nutrition, and cold protection.

Fertilizing

The following table can be used as a guide for citrus fertilization, which is typically conducted between February and September for all types of citrus.  Fertilizer amounts are based on the age of the tree and the fertilizer analysis.  Consider year 1 to be at planting, or the first year after transplanting.

Pruning

Pruning of citrus can be performed anytime, although very little pruning is required.  Remove any shoots growing below the graft union as these are coming from the rootstock and are typically more vigorous than the scion.  If allowed to develop, they can overtake the tree.  Prune as needed to control shape or remove diseased or rubbing branches.  If fruit loads are extremely heavy, remove young fruit to avoid limb breakage.  Removing excess fruit may also reduce the chance of getting a heavy crop one year and none the next.  This is a common occurrence with many fruit trees and is referred to as 'alternate bearing'.
