Nutsedge

What is Nutsedge?

Nutsedge is a common weed found in many home lawns and other turfgrass areas in the United States. There are many different types of Nutsedge but Yellow and Purple are the most common turf pests. Nutsedge is easy to distinguish in your lawn due to their characteristics in growth habit, light-green color and rapid growth rate, resulting in a nonuniform turf.

Although nutsedges are often referred to as “nutgrass” and resemble grasses, they are not grasses but true sedges. Their leaves are thicker and stiffer than most grasses and are arranged in sets of three at the base. Yellow nutsedge has light-brown flowers and seeds, and purple nutsedge flowers have a reddish tinge and the seeds are dark brown or black.

Life Cycle of Nutsedge

Yellow and Purple nutsedge are perennial plants. They usually die in the fall as temperatures decrease, and the tubers and rhizomes of the plant survive in the soil to sprout the next spring. Tubers are usually in the top 6 inches of the soil and can remain dormant for up to 3 years before germinating.

Managing Nutsedge

The key to managing Yellow and Purple nutsedge is limiting the number of tubers and their production. Removal by hand of small plants before they have 5–6 leaves can have an effect if done every 2–3 weeks during the summer. This weakens the plant by eventually depleting its energy reserves in the tuber.
