Well, nevermind. My neighbor came over and grabbed a branch, pulled and the whole thing came up out of the ground. It's gone, the ants got a hold of it. He said it was so old and the ants just took advantage. You could see the trails they made in each branch. Now I need to dig out the mulch and border and then we're going to pull what's left of the rootball out.
RIP Lilac.
