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.

Yellow Nutsedge 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.

To successfully get rid of yellow nutsedge, you first need to do a little research on the weed and be armed with some knowledge so you can know what conditions this type of weed likes, it's tendencies, what it doesn’t like and then based on the information, approach with an effective control program.

How To Get Rid of Yellow Nutsedge: Solutions 4 Step Process

Step 1: Identification. When yellow nutsedge starts to rise up in the springtime, it doesn't take long for them to become a huge issue and start taking over. The problem which often takes place is that lawnowners not familiar with how yellow nutsedge looks may confuse the weed with another grass which can bring about even more problems. Identifying the unwanted plant that is growing on your lawn is vital because once you can correctly ID the weed, you can then research and find out which active ingredients, herbicides and cultural methods work best to tackle that weed and which products are specifically designed to target it. Improperly ID'ing a plant may result in waste of time and money purchasing herbicides which won't work to control the plant.


Yellow Nutsedge are most often confused with plants like purple nutsedge, green kyllinga and white kyllinga. Yellow nutsedge can be most easily recognized by its shiny yellowish green leaves, triangular stem, golden-brown flower head and shallow rhizomes (horizontal underground stems) that produce many nut-like tubers. The plant has rhizomes and tubers which can be fibrous, wiry and dark brown as they mature. The stems are 3-sided and triangular in cross section and the leaves are yellow to green in color with a unique ridge.

 

If you're haveing some trouble determining exactly which kind of weed you are encountering in your yard, turn to the experts to ID the weed for you. We recommend taking a high resolution photo of the unwanted weed with your phone and shoot it over to our email address at Identification@solutionsstores.com. We will respond back to you quickly with not only the correct ID of the plant, we will also give you expert recommendations of products and techniques to apply to remove that weed from your lawn.

 

Step 2: Inspection. Conduct a thorough inspection of your lawn or landscape to see where the yellow nutsedge is growing. Yellow  nutsedge is a very troublesome noxious weed and can grow in a variety of different soils and climates but is most prevalent in the summertime. Yellow nutsedge thrives in seasonally flooded sandy loam bottomlands where it can be introduced by floods. Often, loams sold in garden centers are contaminated with nutsedge turions that quickly establish and create persistent weed problems for homeowners. It can also be a problem in potted nursery stock


Yellow nutsedge prefer areas with high moisture and they also love sunny areas. You don't see this weed growing in shady areas. In this phase you want to see where the yellow nutsedge is growing and what conditions you have so then you can address the issue with cultural practices. This will also help you to determine how much chemical product you need to control the problem and where to zone in when it comes to treatment.

 

Step 3: Control. Chemical control may be the best way to deal with this stubborn weed due to its noxious and persistent nature. A couple of herbicides we suggest Glyphosate 4 Plus Weed Killer Concentrate or Sedgehammer Nutsedge Killer which is specially made to control nutsedge.

Read all labels and instructions carefully with whatever herbicide you choose to use. If you have desired grass around where the purple nutsedge is growing, you can choose to spot treat. Either way, be careful when using herbicides in general around your desired plants as they could potentially kill your wanted turf. Also, please be sure that when handling any type of herbicide, you are properly protecting your skin and eyes with safety equipment. Goggles, gloves and love sleeved clothing should suffice.


For best results, make sure to apply herbicides at the right time. Yellow nutsedge should be treated with herbicides when it is actively growing between the months of May of September. Apply post-emergents in the springtime when the growth is less than 6 inches in length or apply pre-emergents in the fall or early spring to keep their seeds under control. Repeated applications may be necessary so apply every 4 weeks during the growing season.


Step 4: Prevention. You can prevent the return of Yellow nutsedge after it has been controlled with cultural practices that will hinder the redevelopment of this invasive grassy weed. The best preventative measure against bermuda grass is to maintain healthy, thick turf. Mow your turfgrass at the right height and address drainage issues. Don't water so frequently and  and fertilize at the appropriate time and rate. You can also look into pre-emergents if you're worried it will be a problem that will come back.

Learn More About Yellow Nutsedge

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.


The yellow nutsedge will come into the yard from seed and once it's established in the yard, it produces little nuts under the ground. Yellow nutsedge is well-known for its ability to colonize poorly drained or constantly wet areas, it will also flourish in hot, dry areas as well.

Yellow Nutsedge Control Options

Recommended Pre-emergent and Post-emergent Herbicides: Sedgehammer Nutsedge Killer, Image Herbicide - Kills Nutsedge, Celero Herbicide, TenacityHerbicide

 

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.
Yellow nutsedge is most effectively treated before the tubers start to develop in mid-summer. That means using selective sedge herbicides earlier in the season than has commonly been done in the past. It may be earlier than your customers notice the problem. (Start now, not in August). Herbicide treatments aren't as effective once yellow nutsedge is big, spreading by rhizomes and developing tubers.

Removing plants before the 5-6 leaf stage puts a halt on tuber formation and weakens tubers that have to re-sprout. Most post-emergent herbicides labeled for nutsedge specify applying around the 3 leaf stage of growth so timing is crucial. Pre-emergent control of yellow nutsedge in turf is also possible using the product Eschelon. Turf managers that have tried it report that the pre-emergent helps reduce the amount of nutsedge that emerges and also slows or stunts the growth of plants that do emerge. Follow ups with post-emergent products are necessary.


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.
