re: Issues with St. Aug yard

I dug up a big area of quackgrrass and put down sod and it's settled in nicely. Now I'm seeing quack grass starting to pop up again around the edges of the sod and one right through the damn sod. Propiconazole doesn't kill it after further research and finding it popping up. Looks like Roundup is the only thing going to kill it but looks like it can also kill the St Aug in contact with glyphosate
