Is this peach tree borer damage?
About a week ago, I notices what looks like small gouge marks and splits in the bark of my Tropic Sweet peach tree's trunk. It is a new tree that I planted last fall. I'm trying to figure out if this is peach tree borer holes or if there is some other cause.
These were the first holes to show up. They are the most worrying because they are right at the graft.
This one is about half way up the trunk.
Most of them are not bleeding any sap, only 1 that started out looking more like a split in the bark than a gouge has sap bleeding from it. This one is near the top of the trunk:
The holes do not seem to be deep, and I don't see any bugs inside them. I've dug the soil back from the base of the tree and inspected it and don't see any damage below the soil line. And I've not seen any insects on or around the holes. Any idea what is going on? More holes seem to be forming, so it seems like something I need to treat, but
I'm not sure what it is.
Anybody know what is going on? Do I need to treat this? If so, what sort of treatment?
