How To Kill Nutgrass Using An Herbicide
Here is how to kill nutgrass using a post-emergent herbicide that contains halosulfuron or sulfentrazone. Using a selective herbicide to eliminate this tough weed requires specific measures of safety during application.
Most grass types are tolerant of these herbicides, including cool-season grasses, warm-season grasses, and bermudagrass.
- Nonionic surfactant
Read the label directions for your particular brand of herbicide, whether it is Ortho, Sedgehammer, or another brand name.
The general rule of thumb for applying herbicides to the lawn is not to mow the grass two days before and after application and avoid spraying the herbicide if expecting rain. Some brands may require using a nonionic surfactant in addition to the herbicide.
Effectiveness And Other Control Methods
You may need to use the vinegar spray on nut grass two or three times before it is actually effective. It should be noted that sometimes vinegar is not enough on its own. Other natural control options include hydrogen peroxide and horticultural molasses. Combine 1/4 to 1/2 cup of liquid horticultural molasses per gallon of water, and use pour it on the desired area. You may need to apply this method two to three times as well before seeing results.

What Is Nutgrass Or Nutsedge
Nutgrass is a common problem in summer lawns. Yellow Nutsedge is a perennial, grass-like weed that tends to be prolific in poorly drained or wet areas. This weed is not a grass, its a sedge, and its very difficult to get rid of. Nutsedge has triangular stems with leaves that branch out in three different directions and is a light green to yellow color. Nutsedge grows quickly in spring and summer, outgrowing grass in just a couple of days after mowing.

Can I Pull Up Nutgrass
Avoid pulling the nutgrass plant by hand. Pulling nutgrass will stress the plant and stimulate even more nutlets to sprout. Nutgrass plants regenerate from small nutlets formed on their root system under the soil surface. These nutlets go unharmed by traditional contact weed controls, making nutsedge challenging to control.

Nutgrass, more accurately known as nutsedge, is a common weed in lawns. This includes lawns made of bermudagrass , a lawn grass variety grown throughout U.S. Department of Agriculture plant hardiness zones 7 through 10. You’ll likely encounter two types of nutsedge: purple nutsedge and yellow nutsedge . The former thrives in USDA zones 9 through 11 while the latter grows in zones 8 through 11. If you notice nutsedge in your lawn, you have several options for controlling and killing this weed.
Removing Nutsedge By Hand
To successfully get rid of nutsedge by hand you have to remove the plant including all of the roots, tubers, rhizomes, and bulbs. These are found in the top 12-18 inches of the soil.
To do this youll have to dig with a trowel next to the nutsedge plant. Once youve dug around the plant and loosened it in the soil, you can gently pull it out, taking care not to break off roots and leave them behind.
After the plant and root system is removed, continue to dig out any leftover roots you can see in the soil. And throw everything you remove in the trash.

Get Rid Of Nutgrass By Hand
One of the easiest and effective ways to control nutsedge is to remove it by hand. This strategy is crucial to use in areas like flower beds, where a tough weed killer may also destroy your beloved plants.
Its also the best way to ensure you remove all parts of the plant right down to the root system. Use this system to kill weeds but not grass, flowers, or veggies. It may take a little time, but its worth it.
- Garbage bags
How to get rid of quackgrass, nutsedge, and other annoying weeds in the garden or lawn starts with wetting the soil surface. This step softens the earth around the roots and makes it easier for you to pry the plant loose. Next, dig into the soil with the shovel until youve uncovered all parts of the plant.
Its important to note that the root systems may grow up to a foot and a half deep. As a result, yanking them out too soon may leave part of the roots still in the ground and leave you with the same weeds in the future.
If you dont remove all of the roots, then this only allows the plant to grow back in the future. Finally, once you remove the plant, stems, tubers, roots and all, toss it into a trash bag to prevent it from spreading.
Ways To Prevent Nutsedge From Sprouting
When it comes to lawn care, prevention is always the best form of control.
While it is possible to manage and treat Nutsedge in your lawn, it can be very difficult considering how fast this weed spreads and grows.
In the long run, prevention is a much more cost effective solution, and it is considerably less work.
Here are some things you can do to prevent Nutsedge from invading your lawn:

What’s The Difference Between Purple Nutsedge And Yellow Nutsedge
If you are wondering what the two varieties of nutsedge look like, Yellow and Purple nutsedge may look very similar, but there are some key differences between the two. Yellow nutsedge has light green leaves that come to a gradual point, while Purple nutsedge features a darker green leaf that comes to a more abrupt point.
The sedge weeds leaves arent the only difference in color: the seed head for Yellow nutsedge is yellowish-brown as compared to the purple to reddish-brown color found in Purple nutsedge weed. While Purple nutsedge is not as cold tolerant as its Yellow counterpart, it is more difficult to control, in part due to the more complex tuber system connected by rhizomes, which are underground stems that also serve as storage organs for the nutsedge.

Ways To Kill Nutgrass For Good
If you are striving for a streamlined landscape, nutsedge is most likely not in your grand scheme of things. Instead of dining on Tigernuts you just want to kill nut grass for good. You arent alone. Here are some ways for controlling nutsedge in your lawn, so it leaves for your lifetime:
Since nutsedge grows via tubers rather than roots, you cant simply pull it out of the ground. You have to dig deep, often as far as 14 inches down in order to get at the real root of the problem.
Dont forget to grab the nutlets and seeds of the plant when removing it. If left behind, a single seed will respawn this aggressive plant.
After you dig up the nutgrass, use a mesh screen to sift through all of the soil surrounding the plant. This will help you find those seeds and nutlets hiding in plain sight.
Bag up the nutsedge and burn it if you are feeling particularly unhappy with this weed. It is not toxic when burned, but you might not want to toss the ashes in your compost pile out of fear that the weed will return.
How To Identify Nut Grass Weeds
The first step in getting rid of nut grass is making sure that you can properly identify it. If you have a clean-cut lawn then the nut grass can be pretty easy to identify. However, if youre prone to letting your lawn do its own thing, it can be a bit harder to spot. Heres what to look for:
- Both yellow and purple nutsedge have distinct, colored leaves.
- Nutsedge can grow quite tall and produces spiky, clustered flowers of yellow or purple
- Nutsedge has a triangular stem, which is different from common grasses which have round stems
Nutsedge tends to first take root in areas of your lawn that have bad drainage and remain moist. If you dont catch them early they can quickly colonize your lawn with deep root systems.

Ridding The Lawn Of Nut Grass
Q.) Our back yard has been over taken almost completely by nut grass. There is hardly any grass left except the extreme edges. What do we do? Should we tear it all up and start over? Or is there a weed control product that would work?
Nut grass, also known as nutsedge, is difficult to control because it has little nuts or tubers on its roots from which it can sprout anew when the top of the plant is destroyed. It also spreads by seed.
There are several products that will eliminate it from your yard. The best product is called Manage, which is now sold as Sedge Hammer you may have more luck finding it on-line than in your local garden center. The other product is called Image Nutsedge Killer which may be more readily available in your local gardening center.
With either product be sure to follow the instructions to the letter and avoid applying it when the weather is windy to avoid damaging the rest of your landscape. Both products will require more than one application so it may be a two year process before complete control is attained. Apply the herbicide as soon as possible wait a month or two and apply again when the nutsedge reappears.
If you tear it all up and start over, you will continue to have problems with the nutsedge unless you can remove all the nutsedge roots, nutlets and seeds. As with any chemical, use with caution and be sure to read the label for proper application instructions. Also be sure it is compatible with your type of lawn.

Kill Nutgrass With Boiling Water
If youve never used boiling water to kill Nutgrass, it works by collapsing the weeds cell structure, and kills it. Nutgrass being a stubborn weed may need more than one or two treatments, but once done makes it easy to pull and remove the Nutgrass from your lawn.
Since any plant will probably die when scalded with boiling water, it is highly recommended that you not use this Nutgrass killing solution near valuable plants. Boiling water can also be used to disinfect the soil prior to planting new seeds.
