Does Roundup Kill Nutsedge

How to Kill Nutsedge in Lawn

Roundup is effective at killing all kinds of nutsedge. The Glyphosate in Roundup will infiltrate sedge plants through the leaves and travel to the root tubers, killing the sedge completely. However, Roundup is a non-selective herbicide. It will kill any actively growing plant exposed to it, including your lawn grass.

  • Yes, Roundup will kill nutsedge, including root tubers. This prevents sedge regrowth.
  • Roundup will also kill turf grasses and any other plants exposed to the herbicide.
  • Only spray Roundup on nutsedge growing in areas where desirable plants and grasses wont be affected.

Non-selective controls for nutsedge, such as Roundup, must be handled with care. Carefully block off other plants and grasses to prevent exposure, or use Roundup only in areas where sedge is growing away from desirable grasses, such as in driveway seams and sidewalk cracks.

Use Boiling Water On The Weeds

If youve given the other natural weed killers a shot and are still dealing with nutgrass poking up out of the ground, it might be time to move on from chemical solutions and try brute force.

Nutsedge cant tolerate boiling water, and that means that careful treatment with it kills them off. Boiling water also kills everything else around the weeds, too, so its best to use this option when you arent trying to save plants in the same area.

After youve dressed in safety gear, take the tea kettle out to the infestation, and slowly pour boiling water over the plants. Repeat every day for three weeks, until the plants go brown and die. If you have ant problems in your garden or lawn, boiling water gets rid of them at the same time.

How to Kill Nutsedge in Lawn

As we enter into the warmer months, its not uncommon to start seeing pesky weeds pop up in our lawns and gardens. One of the infamously hard-to-control weeds is known as nutsedge and there are several variations of this weed. Yellow nutsedge and purple nutsedge are the most common in the United Statesand both can quickly turn into monsters for your yard. Unfortunately, this weed will continue growing all summer long and until the first freeze of winter.

Unlike other common lawn weeds, nutsedge does not fall into the grassy or broadleaf weed category but is instead a class of its own. Although similar in appearance to a grass, it can be differentiated by its shiny yellow-green color and V-shaped stem that will feel triangular in your hand when it is rolled between your fingers. The yellow nutsedge has yellow seedheads while purple nutsedge has purple seed heads.

Found throughout the United States, it is quite common to see nutsedge in moist areas of the lawn that are poorly drained, especially during periods of hot weather. This Sod University article discusses the characteristics of nutsedge and highlights the weed control product SedgeHammer+, one of the most renown products that controls this obnoxious weed. First, lets discuss nutsedge and its characteristics.

Don’t Treat The Symptom Treat The Cause

When you use a chemical, you’re treating the symptom of the problem, the Nutsedge, and not doing anything to address the root cause of the problem. The true issue is poor soil that holds water for extended periods of time. The best way to start to eliminate Nutsedge organically is to eliminate the conditions that are causing it to thrive, which are moist and compacted soil.

It’s possible that you might need to physically put drain pipes in your lawn to help with congested water. We’ve also had success doing multiple applications of our product Liquid Aerator to help improve the drainage and allow the soil to better circulate air and water. It’s not an instant fix by any means, but we’ve seen a gradual decrease in the Nutsedge level where we’ve done multiple applications over the course of a few seasons. I would recommend 2-3 treatments in the Spring and another 2-3 in the Fall. Alternatively, you can sign up for our Liquid Aeration service and we will come and professionally aerate your lawn.

Using Natural Weed Control Measures

Aside from chemical options, it is possible to kill nutgrass naturally using homemade remedies. They are ideal if you dont like the idea of adding chemicals to your lawn or garden.

However, you should note that they are not selective. You should, therefore, use them with caution:

The following are some of the top natural remedies for killing nutgrass:

1. Vinegar

Vinegar contains acetic acid that can burn the leaves of the nutgrass, killing the plant. For the best result, use vinegar with 10% or higher concentration and spray it directly to the nutgrass.

You might need several applications to completely kill the weed.

2. Molasses or sugar

Sugar might seem like an absurd idea, but it is an excellent natural weed solution. It encourages lawn grass and other plants to seek out nitrogen, making them more competitive.

As a result, the weeds lack nitrogen and theyll die off. You can use granulated sugar on your nutgrass, or spray horticultural molasses.

3. Liquid dish soap

Liquid dish soap is another powerful natural nutgrass killer. It coats the leaves of the plant, interfering with their physiological processes.

It is also a great surfactant, which you can mix with other natural or chemical agents for increased effectiveness.

4. Burning

If your nutgrass is driving you nuts, you can grab a blowtorch and go to work on it. However, the flame will only kill the top growth not the tubers growing underground.

    Can You Prevent Nutsedge

    If allowed to grow to full maturity, nutsedge will develop seed heads that will spread and create more nutsedge in your yard. A pre-emergent herbicide applied to your yard in spring will kill these seeds as they sprout, but it wont kill all the nutsedge in your yard. Heres why:

    • Mature nutsedge plants are perennials. This means they come back each year from tubers in the soil. Pre-emergents wont kill nutsedge roots and tubers.
    • To control nutsedge, kill mature plants with a nutsedge herbicide. Then, use a pre-emergent to kill any new nutsedge weeds as they sprout in spring.

    Unlike Crabgrass and Poa Annua, both purple nutsedge and yellow nutsedge are perennial plants. While crabgrass spreads seeds and then dies, nutsedge spreads its seeds and then goes into dormancy, only to sprout again from the root in spring. If you dont kill nutsedge down to the root, youll continue to battle it year after year.
