Please be sure to read the product label of any insecticide you choose to use to get information on the personal protective safety gear you will need. In most situations, it is recommended that you wear long pants, a long sleeved shirt, closed toe shoes with socks, chemical resistant gloves, and goggles. In areas where ventilation is poor, a manufacturer may recommend you wear a mask or a respirator. We have put together two different safety kits that will make selecting the correct safety gear easier for you.

Nutsedge Looks Similar To Grass Blades

Nutsedge, also known as nut grass, is a weed commonly found in lawns during the summer. These weeds stand taller than the grass in your lawn and are notoriously hard to get rid of given their immersive root systems. Nutsedge is a perennial sedge, meaning it is a grasslike plant that will live for at least two years and will come back year after year.

Use this guide to identify nutsedge in your lawn. Then, read the rest of our 4-part guide to learn how to get rid of nutsedge and where nutsedge grows.


nutsedge taller than grass

Nutsedge is easily identifiable from grass because it is taller than grass. Nutsedge grows much quicker than grass, even after being mowed.

Nutsedge weeds, like all sedges (grasslike plants), have a triangular stem that can be felt in your hands. The stem of the sedge feels like it has 3 sides or 3 points, much like a triangle.

Leaves and Flowers

Nutsedge looks like long grass blades. At the end of a nutsedge stem, you will commonly find 3 leaves and flowers. The flowers can be different colors but are most commonly yellow or purple (dark red).

Yellow nutsedge, or nutsedge with yellow flowers, often grows in the middle of the summer while purple nutsedge (nutsedge with deep red or purple flowers) grows in the late summer.


nutsedge weed anatomy

Nutsedge is typically identified by its root system. Nutsedge has roots, called rhizomes, that can reach 8-14 inches below ground. Rhizomes will grow horizontally under the soil and emerge out of the soil to form a new sedge plant. This means multiple sedges may be connected by one series of rhizomes.

The roots will also have small, starchy tuber structures (known as "nutlets") attached. If you see nutlets in the roots of the plant, you know for certain you have nutsedge.
