In some cases the fruit will shrivel and fall off the tree but sometimes it will remain, the fruit will mature and can be eaten but you will need to cut around the blemish. Winter hygiene, proper pruning with clean disinfected tools and dormant spray can help control pests and diseases on peaches.

Jul 06, Balls of sap will form from any wound to a peach tree or the fruit. Infections will cause this as seen in gummosis, but so will a wound to the trunk from a borer or anything else. As to what might cause the gashes on the trunk, that could be anything from a mower, weed eater, or even bushleaning.barted Reading Time: 7 mins.

Botryosphaeria will cause a brown discoloration in the wood and you may be able to see this if you cut off a twig.
