How To Control & Kill Nutsedge or Nutgrass
This aggressive weed looks like pale grass. Deep roots give it an advantage, but here's how to beat it.
Nutsedge is a perennial, grass-like lawn weed that is lighter green and grows faster in hot weather than our lawns. It prefers moist soil but will thrive even in dry soil. It can be distinguished from grasses by its V-shaped stem. Nutsedge produces tubers, called "nutlets" and rhizomes below ground that sprout new plantlets in late-spring through mid-summer. Individual nutsedge plants may eventually form patches of 10 feet or more in diameter.
This Grassy weed Is Not Technically a Grass; It's a Sedge and Is Very Difficult to Control
Nutsedge, also known as nutgrass, seeks out the moist, poorly drained sections of your yard. Its leaves are grasslike and yellow-green, while the spiky head is purple or yellow. It's a tough weed to control because it grows from tiny tubers, or nutlets, that form on roots that can grow 8-14 inches deep in the soil. Pull out the roots and some tubers will stay behind to grow.
Prevention and Maintenance
Mow High to Help Control Nutsedge
Depending on your turf type and latitude, you can help control nutsedge or nutgrass by changing the way you mow. Mowing your lawn at the proper height, which in most cases is one of the 2 highest settings on your mower, lets the grass crowd out nutsedge and other weeds. Mowing short stimulates nutsedge.
