When & How to Fertilize Citrus & Fruit Trees in Arizona
Regular feeding can help support healthy growth and fruit production, but when and how often to fertilize depends on the type of fruit tree you're growing. Here's a general guide for citrus and fruit trees planted in the ground in Arizona.
When to Fertilize Citrus Trees
Citrus trees generally benefit from three fertilizer applications throughout the year, with the timing varying by the type of citrus you're growing.
For oranges, mandarins/tangerines and grapefruit:
- January–February
- March–April
- May–June
For lemons and limes:
- January–February
- March–April
- August–September
The amount of fertilizer your citrus tree needs depends on its size and the fertilizer you're using. Always follow the product label for application rates and directions, and water thoroughly after fertilizing.
Growing citrus in a container? Container-grown citrus has different considerations when it comes to feeding, watering and general care. Visit our How to Grow Citrus Trees in Containers in Arizona page for more information.
When to Fertilize Deciduous Fruit Trees
Deciduous fruit trees commonly grown in the Valley of the Sun—including apples, peaches, nectarines, plums, apricots and pears—are generally fertilized once a year in February or March, as they begin their spring growth.
The amount of fertilizer needed varies by the type and size of the tree, as well as the fertilizer you're using. Always follow the product label for application rates and directions, and water thoroughly after fertilizing.
What About Fertilizing Figs, Pomegranates & Other Fruit Trees?
Not every fruit tree needs the same amount of fertilizer or follows the same feeding schedule. Established figs and pomegranates, for example, may need less fertilizer than citrus or deciduous fruit trees. Other tropical and subtropical fruits can have their own feeding needs.
For fruit trees not covered above, follow the fertilizer label and recommendations for the type of fruit you're growing, or ask one of our Trusted Garden Advisors for help choosing the right fertilizer and feeding schedule for your tree.
