I had the same problem. There has been so much rain it is causing the trees to suffer so they are dropping the fruit to try to survive. Right now I'm not even sure if my trees will survive all the rain. I am worried about root rot. My trees were loaded and not all the peaches have fallen off and most of the leaves have dropped. The ones that are left are all drooping,

I was so hopeful for a bumper crop. What a disappointment. Maybe next year. Seems like every year it's something. Last year it was a late April ice storm that did them in!

If you can, plant fruit trees including peach on berms. Your tree will establish faster and is less likely to be affect by flood. Most fruit trees do not tolerate wet feet/standing water.

When I had 10 straight days of rain, my peach trees dropped many perfectly green healthy leaves. The trees were stressed. Fortunately, my soil absorbed water quickly.

Squirrels prefer ripe or ripening fruit to green ones.

Normally water would of not been a problem but this year we have had the worst flooding in a century. I have standing water on a slope leading down to one of my ponds. There is not much you can do when you get that much rain. We have oaks trees that are over two foot in diameter that have fallen over because the ground is so saturated.
