Several months ago I had two large liquid amber trees removed from my front lawn. They had an extensive surface root system, so I had the roots ground as well. Well, obviously some of the roots remain underground, as now I've got several places where little trees are sprouting from the ground. I was about to put down a new lawn, but I'm concerned about these little trees continually popping up. Is there a way to permanently kill what's left of the liquid amber tree's roots so no more mini trees pop up?
