Thin them a lot. Peaches set too many fruit. A rule of thumb is one peach per every 4-8". Leaving too many fruit results in smaller fruit with poor quality and worse, branch breaking.

30 peaches, I would thin down to 5 fruit. If you want, thin them down to 10 the first round and down to the best 5 later ( within two weeks. Thinning is helpful when you do it when fruit are young, the younger the better. New growers often have a hard time thinning any of their fruit, not just peaches.

Protecting peaches from all kind of insects is a lot harder than thinning.

Thanks that is super helpful. I had no idea that peaches needed such heavy thinning. I went ahead and thinned it down to five. Unfortunately the tree is not looking very healthy so I think I may have to remove the remaining fruit. A lot of the leaves have yellowed and dropped off the tree. This Spring has been really rough on the young trees. First it was super wet, then we have a really late freeze that bit hard enough that many young trees lost leaves and twigs. The peach seemed unaffected by that but then it got unseasonably hot (85+ degrees) with 30 to 40 mph sustained winds. Many of the trees that were unaffected by the freeze seemed to develop mechanical and/or scorch damage from the hot windy day. I presume that's what got the peach tree too. It appears to be putting on new growth but I assume it would be best to remove the fruits and let it focus on recovering from the weather damages.
