First things first: I don’t have a picture. I tried, but the issue at hand is quite close to the ground, and I’d have to remove the hardware cloth I have around the tree to take a good pic, and I’d rather not do that if it is possible to resolve this by a description.
I noticed my Myro rootstock on my apricot has some gummosis.
The area the sap is coming from–the best thing I can compare it to is almost when you cut a branch from a trunk but cut it flush from the tree. It is a circular/oval area, a bit sunken in. I see no blackness or anything that might look like disease (though that doesn’t mean it isn’t, of course.)
I thought perhaps borers, but did not see a hole, but nevertheless poked around a bit with a wire and still did not discover a hole. (It is in a bit of an awkward location, though, so it’s possible I missed something.)
The only other thing of relevance (perhaps) is that’s i only noticed it a few days after we had a bad storm where several inches were dumped on us. I couldn’t swear, though, that it wasn’t there before.
The tree itself looks great as of now, but I don’t want to let this go in case it’s an issue.
Oh, and I think it’s unlikely it was a mechanical injury (at least one caused by me.). The tree is surrounded with a foot of mulch (and hardware cloth) so I physically can’t get close enough with a weed eater or lawn mover to cause damage.
Does anyone have any thoughts? Or is this definitely one I’m going to need to take a picture of?
