Yellow nutsedge (Cyperus esculentus) —sometimes referred to as nutgrass—is a persistent weed problem in lawns, athletic fields, and golf course turf. It thrives in moist, poorly drained soils and can persist in full sun and moderate shade. An aggressive weed, it spreads via underground stems and tubers. Many turf managers and homeowners find its yellow color, coarse texture, and fast growth rate objectionable in stands of cool-season turf, which also makes it relatively easy to identify. Stem bases typically show a reddish hue when outer leaf sheaths are stripped away. It also has yellow nutsedge has angular, three-sided stems, which can be detected by holding and turning the stem base between thumb and index finger. Fortunately, yellow nutsedge can be controlled using good cultural practices and proper herbicides applied at the correct stage of growth, which usually occurs late spring or early summer. (This month is ideal). A perennial, new plants are primarily produced from nodes on rhizomes and from tubers, which can overwinter. Tubers typically begin to form at the tips of rhizomes in late June or early July. A single plant can produce multiple tubers which can remain dormant in soil from one to several years before germinating. Leaves and stems emerge in spring and grow rapidly during warm weather in summer when leaf growth of cool-season turfgrasses slows. The foliage of yellow nutsedge dies back in the fall following the first hard frost. Cultural management Yellow nutsedge is typically introduced through soil contaminated with tubers and rhizomes. ...
