I cut my peach trees in late winter to open them for the growing season. Everything went fine with thinning and later rethinning. However, in the middle of June to early July, they started developing mold and dropping off the trees. It started as a promising crop, but just fizzled when harvest time came. Bugs were not a big problem as in the past years. I heard the only cure for mold was to make sure the trees were open so the air would not stagnate and create mold. What can be done next year to abate this problem?

Depending on the color and nature of the mold, it could be powdery mildew or sooty mold. Both are fungal issues with one brought on through excessive moisture/humidity and the other by insects pests like aphids. Neem oil can take care of both problems - the fungus and the pests.
