What is Nutsedge? Nutsedges compete against healthy plants for essential nutrients and water. Unfortunately, these weeds can be difficult to identify because they bear a resemblance to regular grass. To differentiate between these plants, you'll need to look closely at their stems. While nutsedges have triangular stems, regular grasses possess round ones.
