Yellow nutsedge is a troublesome, difficult to control weed often found in turf areas. Also known as nutgrass or swampgrass, yellow nutsedge is not a broadleaf weed or a grassy weed, but a sedge, and a thorough understanding of yellow nutsedge is required before it can be controlled.
Life Cycle and Identification: Yellow nutsedge is a perennial plant that reproduces primarily by small underground tubers called nutlets. Yellow nutsedge can also spread by rhizomes (below ground stems). Farmers have difficulty controlling this weed, and as farm land is converted to home sites, the yellow nutsedge plants, as well as nutlets, are often found in the soil of lawns. Yellow nutsedge is most easily identified by the triangular shape of the stem. If you roll the stem of the plant in your fingers, you should be able to feel the triangular shape. The leaves are light green to yellowish in color and are very slick or waxy to the touch. Yellow nutsedge grows most actively during the not months of summer. Often the leaves of yellow nutsedge will grow 2 to 4 inches above the turf canopy. During spring and fall, when temperatures are cooler and growth is slower, yellow nutsedge is not as easily noticed.
If you are being invaded with yellow nutsedge give us a call we can help. If you are already on the turf program we are now applying rounds 3 and 4 which is the grub/fertilizer and spraying any weeds including nutsedge that have popped up.
