Nut grass is a member of the sedge family, and is known as nutsedge. It is invasive, growing from multiple root nodules deep in the ground. Pulling the grass up by the roots will only cause the nodules left in the ground to multiply. In order to completely eradicate you must use a product called Image, which is specifically designed for nutsedge. This product requires two applications, so follow all label recommendations carefully.
