Nutsedge (yellow) is a perennial sedge which is a pest in many cropping systems and lawn areas. It spreads rapidly by means of vigorous rhizomes. In August a nut is formed at the end of the rhizome which overwinters and starts the plant next year. It is apparently not a strong competitor but can become quite thick. The sedges are identified by having a triangular stem. Control measures are available in most situations. A related plant, purple nutsedge (Cyperus rotundus), is not present in New Jersey. It has nutlets in chains on the rhizome and is much more difficult to control.
