When to Plant Citrus
The ideal time in Phoenix to plant a citrus tree is March through June. This gives the tree time to establish before it gets too hot. The second best time to plant citrus in Phoenix is in September and October.
How to Plant a Citrus Tree
Where you plant is as important as how you plant for a citrus tree to optimally grow and flourish. Citrus trees, like most plants, thrive with a foundation of good soil and good drainage. Avoid planting citrus in caliche. Plant in a warm area of your yard. They do well with southern exposure.
To plant a citrus tree you’ll want to dig a hole* that is 3 times as wide as the rootball of the tree. The hole depth should be a little shallower than the rootball.
Plant the tree at or above grade. You do not want to cover the bud union of the tree with soil. Doing so can increase the odds of disease such as Phytophthora trunk rot. This can kill your tree.
*Before digging any holes in your backyard you should call Arizona 811 to avoid hitting any underground utilities.
Grow Citrus in Phoenix: Watering Requirements
Citrus trees are not low water plants. They consume a lot of water. How often you water will depend on the age of the tree and the season. The younger the tree the higher the frequency.
newly planted trees should be watered every few days
As a general rule, established trees (1 year or older) can be watered every 10-14 days in the winter, every 2 weeks in the spring and every week to 10 days in the summer months. As with all plants it is best to monitor the health and growth of your tree and adjust watering accordingly.
Another thing to keep in mind is that citrus is sensitive to salt. Water longer rather than more often. Deep watering pushes the salt in the soil away from the tree’s roots.
Leaching the soil once or twice a year is beneficial for citrus. This practice can help counter the effects of salty water. Powdered gypsum can help as well.

Fertilizing citrus in Phoenix is important and your fruit quality will suffer if you do not fertilize. Citrus trees need to be fertilized several times a year in equal applications.
