My Peach Tree Has Very Light Green Leaves

Question

What does it need? We had a couple of hard freezes this past winter and lost a lemon tree and our pomegranate tree. The peach tree bloomed before it grew any foliage. It has quite a bit of dead limbs and the foliage is lime green, not dark green. We have given it fertilizer a couple of times, but it does not seem to be making a difference. We are in Tucson, AZ. Need your help. Thanks.

I suspect that it may be lacking iron and have chlorosis. This article will help:
