I posted this on the Tree and Shrub forum, but no one replied.

So, I have a peach tree guild and today I was laying a soaker hose around it. I haven't been up close to the tree in some time, as I don't care to step in the guild too much. Anyway, when I laid the hose around the base of the tree I noticed that it had several globs of sap oozing out of the trunk. Maybe four or five different spots with globs about the size of a nickle in diameter. The tree is young yet, about 8' tall. The sap was coming out three to six inches up the trunk.

Should I do anything?

Hi Tom, it sounds like you have Peach Tree Borers which are a really bad pest to have. Sorry to be the bearer of that bad news. I don't know of a natural control for this pest, but as your guild matures I should think many of the herbs will have repellent properties. A quick Google search shows that garlic planted around the peach tree will repel borers. That makes good sense to me and I always grow garlic around all my fruits.

Will it kill my tree, Dave? So far, the tree looks healthy.

Thanks for the garlic tip.

I honestly don't know, Tom. I've never dealt with them before. They surely can't be good for it.

Well, it's all part of learning. Thank you.
