Nutsedge is a common problem for gardeners and homeowners alike. It can be difficult to manage, but with the right tools and techniques you can get rid of it quickly!
Almost 30% of all lawns have some form of nutsedge present. Don’t worry, though, there are effective methods that will help you eradicate this pesky weed.
Let’s start getting rid of it!
Research done by the University of California shows us effective methods to kill off existing nutsedge.
These include:

  • Hand-pulling the weed when it’s still young
  • Using herbicides to target the nutlets
  • Applying mulch to block light and prevent further growth

Preventative measures are important too.
These include:

  • Dethatching the lawn to reduce soil compaction
  • Mowing regularly to prevent the weed from spreading
  • Applying organic fertilizer to encourage grass growth

With the right tactics, you can get rid of nutsedge and keep it away for good!


You can take steps to address the nutsedge problem in your lawn, from preventative measures to chemical treatments. Nutsedge is a type of weed that grows quickly and deep into the soil, making it difficult to manage without proper understanding and care. It’s important to be aware of your surroundings when trying to control this nut grass, as it spreads through tubers or rhizomes hidden underground.

One way you can start is by improving your soil quality; test for deficiencies before adding new dirt or mulch around existing plants. You should also choose grass varieties that are better equipped at competing with weeds like nutsedge; tall fescue is one example of a good choice for preventing its growth long-term.

Organic solutions like hand weeding aren’t effective on mature nutsedge plants, but pulling out young ones may offer some relief if done correctly with a special tool such as an angled weed puller specifically designed for removing them from the ground easily without causing further spread through tubers or seeds dispersal – watch our short video about this method here!

If organic methods don’t work, there’s always chemical treatment options available too. These involve applying different types of lawn herbicides directly onto affected areas. Be sure to read up on ingredients first, and perform spot tests beforehand just in case!

Understanding Nutsedge

how do i get rid of nutsedge
To gain a better understanding of how to eliminate pesky nutsedge, imagine yourself facing down the weed as you learn about its features and control measures. Nutsedge is a problematic perennial weed – light green or yellow, growing taller than most grasses. Prevention is key for controlling this weed, since it’s difficult to manage with herbicides like Tenacity and halosulfuron-sulfentrazone once established.

Natural remedies include cutting out tubers from the root system, opening up your lawn to wild animals, improving soil quality with mowing and top dressing, and regrading your lawn by adding more drainage systems. Flooding waters mixed with mulch/dirt/compost should be avoided.

Hard work goes into keeping weeds under control through regular maintenance. Proper watering techniques (no daily short spurts!), fertilizing regularly for healthy growth rates, and core aeration annually will help keep soils loose enough not to allow nutsedge to take hold.

With careful observation combined with appropriate management strategies, you can successfully eliminate nutsedge without expensive professional treatments, if caught early enough.

Different Methods to Get Rid of Nutsedge

Different Methods to Get Rid of Nutsedge
Mow your lawn higher to help control nutsedge. Use a variety of methods for killing it in or outside your lawn: pre-emergent herbicides like Tenacity, halosulfuron, and sulfentrazone are effective for long-term prevention; post-emergents kill existing weeds; natural herbicides can be used if you have pets or young children around; corn gluten meal prevents growth of tubers; mulching is an option; sedge-specific herbicide formulations such as Sedgehammer Plus Turf Herbicide.

If all else fails, try a weed torch or puller to get rid of the weeds manually – but this requires hard work! You could also hire a professional lawn care service who can improve soil quality with aeration and fertilization treatments, making it harder for nutsedge to take hold in the future.

1 Mow High to Help Control Nutsedge

You can help control nutsedge by mowing your lawn high. This will improve the soil quality and prevent it from taking hold.

Preventive care is essential, so make sure you’re regularly fertilizing and applying proper maintenance techniques like watering strategies and weed prevention methods.

Mowing high keeps the underground tubers of this pesky plant in check. Post-emergent herbicides like Nutsedge Killer Ready-to-Spray provide an effective solution for killing off existing growths quickly.

A combination of these steps, plus regular monitoring, can effectively manage any outbreaks before they get out of hand.

2 Kill Nutsedge in Your Lawn

To kill off nutsedge in your lawn, use post-emergent herbicides for fast and effective results – over 90% of users report successful control!

The best way to get rid of this pesky weed is by using a post-emergent herbicide product. This will ensure an effective solution that targets the nutlets and kills them off quickly.

To supplement this approach, you should also take steps to improve soil quality. Mow correctly, use fertilizer alternatives, prevent weeds and manage irrigation. These cultural controls can help prevent future infestations from taking hold while ensuring a healthy lawn for years to come.

3 Kill Nutsedge Outside Your Lawn

To rid your outdoor areas of nutsedge, use a post-emergent herbicide to target and kill off the nutlets quickly. This is the most effective way to control this problematic weed, as it can be difficult to manage with natural solutions or mowing strategies alone.

Poor drainage and soil health are major contributors to nutsedge growth; however, regular maintenance such as core aeration and fertilizing will help promote resistance against weeds like Nutsedge.

Selective sprays should also be used on an established schedule in order for them to work effectively in controlling infestations outside of your lawns.

If you maintain a healthy environment for vegetation growth through proper irrigation management and care techniques, then you can keep Nutsedge away from your property without resorting solely to chemical control methods!

4 Use a Pre-emergent Herbicide

To ensure nutsedge stays away from your property, you can use a pre-emergent herbicide anachronistically to nip the problem in the bud.
Pre-emergent herbicides are effective against nutsedge as they contain active ingredients that kill off its nutlets before it germinates and sprouts.
Other DIY treatments, such as manual weeding, beneficial nematodes, vinegar solution, boiling water or oil, may work for some instances of nutsedge infestation.
Using a pre-emerging weed killer is usually more effective at targeting long tubers found deep under warm temperatures.
Read product instructions carefully and follow label directions when applying any form of chemical control to keep your lawn free of this troublesome weed.

5 Use a Post-emergent Herbicide

To ensure nutsedge is eliminated from your property, use a post-emergent herbicide. It’s the best form of control for controlling nutsedge and can give you the best results if applied correctly.

Before applying any type of chemical, it’s important to identify and accurately cover all areas affected. Alternatives such as organic solutions or natural methods may be available, but they typically require multiple treatments before being effective.

Using a post-emergent herbicide offers an easy solution while saving time and energy. It’s a good idea for anyone looking for immediate relief!

6 Use a Natural Herbicide

You can naturally rid of nutsedge with a potent herbicide, like snuffing out a candle flame. Organic solutions and natural alternatives are more sustainable practices for chemical-free control over troublesome weeds. Biological weeders can help you manage your lawn care needs without harsh chemicals that could harm beneficial plants or animals in your area.

DIY treatments like controlling moisture levels, regular mowing, core aeration and fertilizing on schedule can help reduce the spread of nutsedge. Using an herbicide tailored specifically for it is key to eliminating it completely from its roots up.

With proper planning and management techniques, organic solutions or natural alternatives available today, you can effectively keep nuisance weeds at bay without longterm damage to your property’s environment!

7 Use Corn Gluten Meal

Take control of your lawn and prevent nutsedge with corn gluten meal – an organic, natural solution that’s easy to use! It’s a by-product of the milling process used for making cornstarch or syrup. When applied as a pre-emergent fertilizer, it can help inhibit the growth of perennial weeds like nutsedge.

But to get the best results, fertilize your soil with 20 lbs per 1,000 sq. ft. before any weed germination occurs. Water the area thoroughly after application. The nitrogen content also helps improve soil quality, making plants less susceptible to pests and disease.

Regular watering frequency is essential. But avoid overwatering, as too much moisture will allow more room for weeds like nutsedge to flourish.

If you want an organic DIY treatment option against pesky perennial weeds like Nutsedge, corn gluten meal could be worth considering.

8 Use Mulch

Investigate the potential of mulch to prevent Nutsedge from taking over your lawn by applying it around plants and soil. Mulching is an organic solution that can help reduce moisture in the soil, discouraging weeds such as Nutsedge from growing. Add a layer of compost tea or other organic matter on top of the mulch for even more effectiveness.

If nutsedges have already taken root in your yard, manual extraction may be necessary for complete removal. Use tools like shovels and hoes, but only when soils are dry for best results.

Another non-chemical control option is solarization. Cover areas with plastic sheeting during hot summer months to raise temperatures enough to kill off weed seeds and tubers below ground level. Take caution not to scorch desired plants!

Some gardeners swear by a thick layer of mulch as an effective way to smother any existing nutsedge growth and prevent new seedlings from germinating. Make sure there’s always adequate soil moisture levels throughout these processes for success!

9 Use a Sedge-specific Herbicide

For successful Nutsedge control, consider using a sedge-specific herbicide. It’s designed to target the weed and is more effective than glyphosate-based herbicides. It can help prevent further infestation by killing off the nutsedge plants before they spread their nutlets in soil moisture areas.

Hand weeding or mowing won’t be enough on its own for long term control. You’ll need to combine it with proper watering, soil testing, aerating and nutrient balancing as part of an overall strategy.

Be sure to follow all instructions carefully when applying any type of chemical treatment. You don’t want to inadvertently harm your lawn or surrounding environment.

10 Use a Weed Torch

Ignite your nutsedge problem with a weed torch, and watch it go up in flames! Weed torches are an effective DIY treatment for controlling the emergence of new plants. They work by chemically burning out young plants at their base. Can be especially helpful in preventing nutlets from growing back again.

Chemical control is one way to manage nutsedge weeds. Cultural practices such as improving soil moisture through adequate irrigation or topdressing lawns can also help keep them away.

A healthy lawn combined with prevention strategies like avoiding overwatering areas where these pesky weeds thrive will help support biological control methods such as using a weed torch on stubborn infestations that just won’t quit.

11 Use a Weed Puller

Tackle your nutsedge problem with a weed puller and make sure it stays gone for good! Hand weeding is one of the most effective, non-chemical DIY treatments to get rid of nutsegde.

By using a weed puller you can remove mature nutsedge from the root without accidentally spreading them further. It also helps condition the soil, loosening compaction to improve air circulation and water drainage.

When used in combination with pre-emergent or organic control methods such as soil conditioning and proper watering techniques, hand weeding is an excellent way to address moisture issues that may have contributed to your weeds’ success in growing on your lawn or garden space.

Invest in quality tools like a durable weed puller made specifically for removing tough weeds like Nutsedge so you won’t be left dealing with this pesky intruder ever again! Get started today.

12 Use a Lawn Care Service

If you’re looking for a permanent solution to your nutsedge problem, consider using a professional lawn care service. Their help and expertise can provide the best course of action for eliminating this pesky weed from your property!

A Lawn Care Service expert can identify moisture issues causing Nutsedge growth, as well as suggest DIY treatments like aerating, fertilizing and shading. These create an environment unfavorable to further Nutsedge germination.

Overseeding with grass species resistant to nutsedge can reduce future infestations. This, combined with the treatments, will give you long-term protection against Nutsedge invasion and great results quickly, compared to doing it yourself or relying on chemical control methods.

13 Improve Your Soil

Take steps to improve your soil quality, which can make it harder for nutsedge to take hold and spread. Organic fertilizers, compost tea, and soil testing are all great ways of improving the health of your lawn’s soil without introducing harsh chemicals. Aeration services will also help break up compacted dirt that isn’t ideal for growing healthy grass.

Nutrient balancing with a spot test can ensure you’re adding just enough nutrients into the new soil so that there aren’t too many or too few; this helps create an environment where weeds like nutsedge are less likely to thrive.

Investing in improving the quality of your lawn’s existing topsoil is a more sustainable approach than buying new topsoil every couple years. It’ll save you money in both time and materials!

14 Plant a Different Type of Grass

To rid your lawn of nutsedge, consider planting a different type of grass that’s better equipped to compete. Reseeding can help introduce healthy turf and crowd out any existing weeds. Research which types will work best in your area and climate. Be careful not to over-fertilize, as this can encourage more weeds and weaken existing plants. Avoid over-watering, too. It can create an environment conducive for nutgrass growth, spreading underground via rhizomes or tubers etc.

Composting techniques like topdressing with organic matter may help improve soil quality, creating an inhospitable environment for weeds including nutsedge – and providing essential nutrients for healthy turfgrasses!

15 Hard Work

Putting in the hard work to maintain your lawn can go a long way towards keeping pesky nutsedge away. Mulching strategies, soil conditions, and grass varieties are all key factors when it comes to preventing an infestation.

DIY treatments such as weed torches or natural alternatives may help but should be used with caution due to potential damage they could cause. Instead, addressing moisture issues through proper watering techniques is recommended for achieving optimal results.

Consider investing in some quality weed control products if you find yourself unable to keep up with regular maintenance. Just make sure you read the instructions carefully before using them.

With enough hard work and dedication, you can beat out this troublesome weed once and for all!
