lemon tree turning yellow
I have a beautiful lemon tree that has one limb that the leaves are turning yellow. I live in the central San Joaquin Valley of Fresno, CA. and am on water restrictions this year of 2 times a week. The tree has a lot of fruit even on the limb that is turning yellow. Any advice?
Most likely the yellowing leaves is a watering issue.
Adding 2 to 3 inches of hardwood mulch can help with moisture retention.
