I have had three peach trees in my yard for 15 years. Just pushed two of them down. The third dropped all its peaches - green - a month and a half ago. I have never sprayed them and never had a peach make it to ripe. I have a few new peach trees coming on that I would like to get some edible peaches from. Those of you who grow peaches successfully - do you stay on a religious two week spraying schedule like most recommendations call for - or do you skip a few and still grow some peaches?
