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