Q.Lemon trees

Zone 85345 | rlhuolt added on December 28, 2015 | Answered

The leaves on our lemon tree have turned yellow. We are in Phoenix, Arizona. What would be the problem? It is an established tree.

Yellowing leaves could indicate a watering issue, to much or to little.
It also can be due to disease or insects.
Here are some links to help you pinpoint the cause.
