|What caused my peaches to shrival and die covered with a gray mold or fungus?
|:It sounds like your peaches have brown rot, which is a fungal disease that overwinters in decayed fruit on the ground and is worse during wet summers. The disease is spread by insects that feed on the fruit, so controlling the insects with an organic insecticide can help. Also, it's a good idea to spray the trees regularly with an organic fungicide. Pick off the infected fruit and be sure to pick up and destroy any fallen fruit throughout the season. I hope you get a better harvest next year!
