How To Remove Yellow Nutsedge From Your LawnGet rid of Nutsedge

Not all sedges are bad but there are some types of sedge weeds that can be particularly problematic when they decide to invade your lawn or garden. One of these sedges in particular is Yellow Nutsedge which can be quite a frustrating challenge for landscapers to control because of its persistence. It can become a recurring problem and common herbicide treatments usually aren’t enough to remove the weed. Yellow nutsedge can be best controlled if it doesn't get established in a lawn in the first place. The weed, which thrives in moist soil where grass is thin, can be controlled by special herbicides designed to specifically tackle sedges. Solutions Pest and Lawn can provide you with the best professional grade products and expert how-to tips on eradicating this problem weed.

Yellow Nutsedge Background Information

Yellow nutsedge (Cyperus esculentus) is a perennial weed that spreads mainly by small underground tubers known as nutlets which form at the end of underground stems called rhizomes. A single yellow nutsedge plant can produce several hundred of these tubers  in the summer time. When left unmown, Yellow nutsedge produces a bristly, brownish seedhead, however, its seeds rarely germinate.

Yellow nutsedge actively grows during the hottest period of summer. In Northern areas, Yellow nutsedge typically emerges in late April or May and grows actively until the first frost of the fall. The frost typically kills the plant aboveground but the tubers underground will survive and overwinter in the soil where they will remain dormant and then emerge in the spring. They can survive in soil for more than three years.

Yellow nutsedge has been a problem ranges and pastures, agricultural lands and in lawns. Yellow nutsedge tubers can easily be spread by soil (topsoil or fill dirt) from one area to another during construction. In addition, people and equipment can spread yellow nutsedge whenever soil is moved during planting.

Yellow Nutsedge Control Options

Recommended Pre-emergent and Post-emergent Herbicides:


Solutions has a variety of specialized herbicides that target yellow nutsedge which you can see above. Professional-use products such as Sedgehammer and Image Herbicide provide the most satisfactory control as they are specifically designed to target nutsedge. These are selective herbicides so they will not harm your lawn grass or desirable vegetation when applied according to label directions.

Timing is key when targeting Yellow Nutsedge; the herbicides we recommend are most effective on small plants. Most of the label directions recommend conducting control treatments as soon as the weeds reach the three- to eight-leaf stage, right before blooming. The plants may reemergy so you may have to reapply it around 6 to 10 weeks later. You may even have to apply it again the next year.

Herbicides are much less effective after tubers form in late summer. Then it would be better to pull the weeds by hand and save the herbicide until spring.

Combine chemical herbicides with organic weed-control methods. While chemical herbicides can take care of the majority of the problem, the best method for controlling yellow nutsedge (and other weeds) is to grow a healthy, nutrient-rich stand of turfgrass that can compete with invading weeds. You can encourage dense turf stands by carrying out proper maintenance practices, like fertilization, proper watering and frequent mowing at the correct height, between 2 ½ to 3 inches.

Yellow Nutsedge Control Tips and Recommendations

  • - A good tool to use to aid with your herbicide application is mixing your selected herbicide with a surfactant. This will help herbicides penetrate the waxy cuticle of weeds such as yellow nutsedge.

  • - Regardless of the herbicide you select, yellow nutsedge is a stubborn weed that may require repeated herbicide applications. Follow label directions about when to make follow-up applications, if needed.

  • - Yellow nutsedge enjoys a moist or wet environment so make sure the soil drains adequately in those areas. Test to see if you have any drainage issues and also make sure you are not overwatering your lawn.

  • - Herbicides can be harmful if you come in contact with it. Keep your body and face protected with safety equipment any time you handle herbicide products

  • - Check out our knowledge base or view our informative How-To Videos to get more thorough step-by-step guidance in applying the herbicides we carry.
