Is there anything that permanently kills nutsedge?
I've been fighting nutsedge for nearly 10 years now. I started with pulling, and when that didn't work, I started spraying Sedgehammer (formerly Manage). The nutsedge would die from the Sedgehammer, but come back. I've even tried spraying twice - once in June, and again in August. It still comes back the following year, just as strong as ever.
Obviously, Sedgehammer kills the top growth, but not the root, or it wouldn't keep coming back. Is there anything that will actually kill nutsedge permanently, down to the root?
