How Do I Permanently Get Rid of Nutsedge

Nutsedge, a tough variety of weed, is often seen in our lawns when it is spring. In fact, this is the time when our lawns start growing vibrantly. But they have to compete with some of the toughest weeds including nutsedges in this season.

If your lawn has fallen victim to this type of weed, then you must be thinking about how you can permanently get rid of these pesky weeds. Well, we will help you get the solution in this article. Just go through the following information with the utmost attention and patience to learn how to get rid of Nutsedge permanently.

Identify Whether It’s Nutsedge Or Not

The first thing you have to do is to identify whether you have nutsedges or any other type of weed in your lawn. This is because you can’t get rid of the problem if you treat your lawn with a wrong product or method.

Generally, lawn enthusiasts get perplexed to identify nutsedge weeds as they are similar to quackgrass. However, if you get to know the characteristics of the weeds, you will find it easy to identify what type of weed you have in your lawn.

For your kind information, you will see a triangular stem when you look at the base of a nutsedge weed. And these weeds have tuber-like nutlets, which help them grow in the next season.

On the other hand, the leaves of quackgrass weeds have auricles, which are like fingers. And they have only fleshy rhizomes at the end of the plant. Though they don’t have tubers, they can grow later with the help of the rhizomes.

Select a Post-Emergent Nutsedge Killer

Now that you have identified nutsedge weeds in your lawn, it’s time to eliminate them permanently. In this case, many lawn owners tend to remove them by hand. But it’s not a permanent solution.

Though you will find it easy to remove nutgrass weeds by hand, they will certainly sprout in your lawn in the next season. The tubers of the weeds help them to come to your lawn over and over again.

This is why you need to use a post-emergent herbicide that is able to destroy the tubers of nutsedge weeds. And before buying a herbicide, make sure you have read the label of the product.

The fact is that different herbicides are meant for different types of nutsedge weeds. If you buy a yellow nutsedge herbicide, you won’t be able to kill purple nutsedge weeds in your lawn. Therefore, be careful while choosing a nutsedge killer product.

Get an Effective Surfactant Product

Buying a surfactant is not a must. But it will help you with a great deal. To clarify, surfactants make post-emergent herbicides stick to the leaves of nutsedge weeds. As a result, herbicides can penetrate the weeds thoroughly.

However, you must make sure you have combined the surfactant and the herbicide properly. Otherwise, you won’t see the expected results. For this purpose, you can use a good-quality hand-pump sprayer.

You should never approach a surfactant directly, by the way. The reason is that some nutgrass herbicides include surfactants and some others don’t work well with surfactants. This is why you must read the label of the herbicide before buying a surfactant.

Prepare Your Lawn for Treatment

Getting an effective product is not all. You have to use it properly to get the best output. And preparing the lawn is the first and foremost thing for proper treatment of nutsedge weeds.

As a newbie, you may wonder how you can prepare the lawn. Well, preparing the lawn is not a cumbersome job. At first, make sure the weeds are not more than 3 inches high because it takes time to kill long nutsedge weeds.

Afterward, you need to make sure whether you have mowed your lawn recently. If you have mowed, then you should wait a few days to get your lawn to grow again. This is because nutsedge herbicides don’t work well when you mow your grass.

You should also choose a favorable day for the herbicide. Typically, nutsedge killers don’t perform well when you apply them on a hot day. Therefore, you must avoid dry weather while going to apply your purchased herbicide.

Treat Your Lawn with the Herbicide

As you have prepared everything, now it’s time to treat the lawn. At this stage, you have to mix the surfactant with the herbicide you have bought. But if the surfactant is not necessary, you can avoid it.

Apply the herbicide with the help of a sprayer. Don’t neglect even a single patch of nutsedge weeds in your lawn; it may bring a large group of weeds in the next season.

When you are done with the application, you must avoid mowing the lawn. As herbicides take time to penetrate the roots of nutsedge weeds, it’s a wrong approach to mow them just after the application.

Retreat the lawn if it is required. Before retreating the lawn, you must wait for a couple of weeks. It takes time to see the result of the first application. However, you should make sure you have read the label to know when you need to retreat the lawn.

Some Tips for the Prevention of Nutsedge Weeds
