Question
I have two peach trees that the leaves are turning yellow, and the peaches have just dried up into almost looking like prunes

Answer
Hi Troy, from what I am reading sounds like your tree has
Peach leaf curl, it is a fungus disease called Taphrina deformans. It can cause defoliation and crop loss on nearly all varieties of peach and nectarine trees. The most common characteristic is the curling and crinkling of the leaves as they unfold in spring. Usually, the entire leaf is affected, but sometimes only small areas are involved. In addition to the curling, diseased leaves often turn red or purple. This disease also may occur on the fruit, blossoms, and young twigs. Diseased fruits will usually fall off of the tree prior to harvest. A diseased tree does not usually yield well do to blossom loss in the spring.

What I think would help and save the tree is Atomic Grow, which will help restore your tree back to health and is totally organic.  It will get rid of the fungus so your leaves will come out nice and green again, and more than likely, better than ever.  kathy
