I have a peach tree and there is an issue with the trunk that I am trying to learn more about and hopefully it is easy to remedy… Can anyone assist with this?
Looks like bacterial canker Pseudomonas syringae. No easy cure that I know of. I don’t know that it can be completely cured. You can help the tree by fertilizing it right, watering it right and make sure to sterilize your pruning tools.

Peaches do not suffer as badly from canker as do cherries, so you will probably be OK. On cherries I cut out cankers, remove all the bark and cambium until you hit clean (non-brown) cambium, then cover it. On peaches I just let it be.

I found some canker on one of my plums and followed these instructions. Seems to work but its too early to tell.
Yeah I too leave them alone on peaches, and most cankers on peaches are fungal versus bacterial more common on cherries. But both can attack either tree. When I spray copper as a dormant spray, I spray the areas. Not sure it does anything? Anyway they seem to heal, I had a bad one on Indian Free peach thought it was a goner, but new bark has grown and the area looks much better.
Gee, I can’t think of a single canker ever on my apricots. Plums have cankered for me but not apricots. I only cut out the ones on cherries as those seem to just get worse and worse.

I have one tree at my cottage that i cut out the canker and it has been fine, but all others have died on me. It’s a Glacier cherry. The cherries are soft, not very fond of those. But happy to have some cherries there. I have to graft others unto it.
