My experience if limited, but I do see a trend such that the early varieties do better. I have nothing that ripens after August. My Early Redhaven starts ripening in late July and it’s almost trouble-free.
For some reason. I’ve also never had trouble with insects (other than hornets) here on peaches, other than hornets. Birds do the most damage. Deer browse on whatever leaves and fruit then can reach – on hind legs! I think the mold damage is often is opportunistic infection after the bird damage.
At a prior location, I had a horrible time with OFM. For three years, I struggled very diligently without good success. Then I stopped spraying and the damage nearly stopped. I wondered if there might be a natural predator that took over when the spraying stopped. But that was just a wild guess. Do hornets eat OFM caterpillars?
