Why & How to Control Nutsedge in North Texas
Sedge Control can be difficult, even by professionals. Trying to eliminate nutsedge by digging it up can be a waste of time. If you kill one shoot, the tuber merely sends up another. For complete control, an herbicide product must translocate down and kill the tuber and all the surrounding nutlets. Understanding how nutsedge grows will help you understand why it can be such a big problem in your lawn.
What Is Nutsedge?
Nutsedge, also known as just sedge or nutgrass, is a perennial plant that reproduces primarily by small underground tubers called nutlets that form at the bottom of underground stems. The underground stems are called rhizomes.
A single nutsedge plant can produce several hundred tubers during the summer. In one year, the reproduction from one tuber has the potential to produce 1,900 new plants and 7,000 new tubers. Yellow nutsedge can also spread by rhizomes. Luckily, individual tubers do not live more than 3 years.
How to Identify Nutsedge in Your Lawn
There are several ways to identify sedges and distinguish them from grasses. Sedge can be identified by the triangular shape of its stem. You can feel the shape by rolling the stem in your fingertips. Sedge leaves are arranged in groups of three, which also distinguishes it from grasses. The leaves are light green to yellowish, and each leaf has a long, tapered tip. The yellowish color is usually easy to see in a green lawn as being different. Each leaf also has a prominent midrib, and has a slick, shiny, or waxy appearance.
How to Control Nutsedge
The best method for controlling nutsedge is to create a healthy, dense, stand of turfgrass that can compete with weeds. Encourage thick turf stands with proper turf maintenance practices, including fertilization, proper irrigation, and frequent mowing at the proper height.
Sedge is most problematic in turf mown too short and/or areas where soils remain moist from poor drainage or overwatering. Sedge can also be a problem in well-drained areas, especially thin turf but it is less likely and won’t spread as easily.
