It has been notorious for crowding out desirable plants on lawns throughout the U.S. f you're faced with a purple nutsedge invasion, there is a Solution and we here at Solutions Pest and Lawn can provide it with our professional grade products and expert how-to tips. Here we will share with you a little about this pesky plant and what it will take on your part to eradicate it from your lawn.

 

Purple Nutsedge Background Information

Purple nutsedge (Cyperus rotundus), also popularly known as nutgrass in some regions, is a common weed in both turf and ornamental areas. Purple nutsedge is typically found in areas which receive full sunlight and areas that enough water and nutrients to maintain its development.. Shade tends to heavily restrict its growth. The plant has slender leaves that are connected to a network of underground stems (rhizomes), roots, and tubers. Although purple nutsedge flowers profusely if not mowed, very few seeds are formed, and few of them can reproduce. As a result seeds are not often the source of new purple nutsedge plants.

The underground tubers and corms (the “nuts” or “nutlets”) are the primary source of purple nutsedge infestations. Some tubers are linked to aboveground growth, but other tubers may not be connected to leaves aboveground. If left undisturbed, purple nutsedge will spread by growing laterally underground, spreading several yards each year. Some other weedy plants can be mistaken for purple nutsedge, these yellow nutsedge (Cyperus esculentus L.), green kyllinga (Kyllinga brevifolia), and white kyllinga (Kyllinga nemoralis), which have leaves similar to purple nutsedge leaves. Purple nutsedge flowers are brownish colored and its tubers emerge in chains.

Purple nutsedge is a serious weed and one best overcome by constant management. A good strategy is to use a combination of chemical and cultural control methods to reduce the nutsedge population to manageable levels.

 

Purple Nutsedge Control Options

Recommended Pre-emergent and Post-emergent Herbicides:

 

Solutions has a variety of specialized herbicides that target nutsedge in general. Aside from the above recommendations, quickest ways to eliminate purple nutsedge is glyphosate. However you have to be very careful when using glyphosate as the chemical is non-selective meaning it is a “kill-all” weed killer so be sure to carefully spray around areas with desired grasses and plants.

For best results, spray the entire area with the glyphosate. Even though the other vegetation there will certainly die, this is the quickest and most effective way of getting rid of purple nutsedge. You can then follow up with reseeding your desired turf. This is usually not the most savory option to lawn owners so that is why we also recommend our selective herbicides which are specially made to eliminate nutsedge.

You should wait until two weeks or so pass before re-applying the herbicide, especially if using a potent one like glyphosate. Weeds are persistent, so you have to be equally persistent to get rid of them. You will probably need to apply the herbicide two to three times, at minimum, before it wipes out the purple nutsedge completely. Wait until after the foxtail reemerges before using another application.

Combine chemical herbicides with organic weed-control methods. While chemical herbicides can take care of the majority of the problem, enlisting the help of certain organic control methods can help in between applications, making the extermination process go quicker overall.

 

Purple Nutsedge Control Tips and Recommendations

  • A good tool to use to aid with your herbicide application is mixing your selected herbicide with a surfactant so that your application can stick to the goosegrass and not runoff.

  • In any herbicide control program for purple nutsedge, it is important not to allow the weed to grow untreated for longer than 3 months.

  • A hand-pump sprayer with a fan tip nozzle works best when treating purple nutsedge. This will shoot a mist that will evenly coat the weed for best results in removing it from your lawn.

  • Herbicides can be harmful if you come in contact with it. Protect your eyes, skin, mouth and nose by wearing protective equipment any time you handle herbicide chemicals.

  • 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.
