Orange tree care is not complicated. Following a few basic steps when taking care of an orange tree will keep your tree healthy and possibly increase fruit production.
If you are taking care of an orange tree that is already established, you may have questions about three important aspects of orange tree care: fertilizing, watering, and pruning.

Water Water needed for growing orange trees varies by climate and yearly rainfall totals, but as a rule of thumb, orange tree care involves regular watering in spring to prevent wilting and withholding of irrigation in fall. When taking care of an orange tree, remember that water lowers the solid content of the fruit. Depth of planting also affects how much water you provide during orange tree care. Growing orange trees usually need between 1 and 1 inches (2.5-4 cm.) of water per week.

Fertilization Fertilization of growing orange trees depends on the use of the fruit. Extra nitrogen fertilizer results in more oil in the peel. Potassium fertilizer decreases oil in the peel. For high productivity of edible oranges, 1 to 2 pounds (0.5-1 kg.) of nitrogen should be applied yearly to each tree.
