Make sure you are spraying an anti-fungal agent on your peach tree each spring. They are prone to several diseases that can wipe out and kill the tree. I had an 18-20 ft tall flat peach tree that died due to this.

No need to spray it. It's very unlikely you have any foliage pest that would match the symptoms you describe. From the rainfall you mention, Desifern is probably correct. Simply too much water. Peach trees are very sensitive to drowning. I've lost lots of peach trees from soggy roots. Sometimes a peach tree will die of drowning in a spot, but another spot just 20' away may have just enough drainage to allow a peach tree to live. Since I've started planting my peach trees in mounds, I've yet to loose one from drowning. My guess is the tree got enough water stress, it's trying to reject the graft. Strip off all the growth below the graft, and watch to see if any new growth appears above the graft. If it does, do as Frank suggests and prune to allow the new growth to take off. I wouldn't go to great measures trying to quarantine any root pathogens from this tree. Phytophthora is pretty much ubiquitous in wet soils anyway. Whether it's phytophthora or wet feet, planting your next peach in a mound will solve both types of root problems.

cough: 1. If you have already planted 8 peach trees, and are still looking for more, I invite you to consider the following sincerely offered suggestions: a) Make sure you know what is involved in growing 1-3 peach trees before you plant a lot more. Growing peaches is difficult even for experienced backyard growers. Peaches can have a lot of insect and disease problems, and usually do. Do not believe anyone who tells you they are easy to grow "organically". b) Before planting a lot of any one thing, have a plan for the use of the fruit in the event you actually get some production. 2. I have a pretty good-size backyard orchard here, and currently have 5 peach trees. I could actually get by with three good varieties, one early, one late-midseason, and one good peento (flat) type. This year, 3 of the trees produced heavily, a mature Golden Jubilee, a young Contender, and a young (white) Sugar Giant. The Contender ripened extremely early -- July 7, and, since early peaches are not much good for freezing, we had to hustle to eat or give away the more than 50 peaches this tree produced. They are all ripe within a period of a week. The average person, weighing less than 300 lbs., can eat a maximum of 2 large peaches per day. Next to ripen was Sugar Giant, a sweet peach without a lot of flavor. It suffered badly from bacterial spot, and at least half the peaches were thrown out. This peach, a modern variety from the Zaiger program in California, was a mistake to plant here. 3. Because of the 4-day Easter freeze, the Flat Wonderful peento type had only a dozen peaches, but they were truly fine eating, and early to ripen. They have a firm flesh, but wonderful flavor. Because of their odd shape, peento peaches are difficult to cut up and prepare for freezing. The little pit resides right in the middle of the doughnut, and the peach does not split apart like a large freestone. If this tree produces a full crop next season, we will again be shoveling them in shortly after Contender is gone. I would be cautious about planting any of the white peento varieties, which are likely to be far more sensitive to brown rot and other maladies. 4. Golden Jubilee is a late-midseason peach, and this mature (12 year) tree was an abundant producer this year, with about 125 peaches, of which at least 3 dozen weighed one pound or more. My spouse froze 16 quarts of these peaches, which are firm, easy to prepare, and fine for freezing. But we still have a dozen of these peaches in the refrigerator. They ripened the last few days of August and early September. 5. The bottom line here is: I really don't know what we would do with any more peaches. Once you have figured out how to grow them, and protect them against all their enemies, they can be very abundant. After two early sprays with Imidan against plum curculio, and careful thinning, all my peaches were bagged in try-on "footies", which protected them against insects (mainly oriental fruit moth) for the balance of the season. And very effectively - without any further spraying. Footie installation is, however, tedious, and calls for some acquired skill. 6. If you are going to grow peaches, you should become familiar as soon as possible with diseases such as bacterial spot (on the fruit), bacterial canker (on the limbs), and insects like the plum curculio (early) and oriental fruit moth (all season long). After that, you can get some advice here on how to deal with those problems. You should select the varieties to plant very carefully, based on such factors as their ripening times, and resistance to diseases like bacterial spot. Planting what Home Depot happens to have on hand is not the best way to choose your peach varieties. 7. Without considerable effort to learn the essentials of peach growing, you can plant 100 trees and still not get any decent, usable peaches. On the other hand, two or three carefully chosen peach varieties, with the right care, can produce enough peaches to make your family tired of eating peaches, and the neighbors too.

You can prune the tree any time you want. It doesn't have to be dormant. But you have to understand that this year's new growth will be next year's fruiting branches.
