Stems are solid, erect, triangular in cross section, and can reach a height of 8 to 24 inches. Leaves are yellowish-green, narrow, sprout from the base of the plant, and appear to grow from three sides of the stem when the plant is viewed from above. Seeds are usually sterile. The plant reproduces primarily by hard tubers, often called nutlets, located at the ends of rhizomes. These tubers overwinter.
New plants emerge from each tuber.
A single yellow nutsedge plant is capable of producing over 100 tubers. Yellow nutsedge becomes a perennial within 3 weeks of emergence. It is often found in wet areas and is troublesome in low areas of cultivated fields and pastures. Control of perennial weeds may require a combination of all these methods. Consider the energy and environmental implications when choosing a method of control.
