These are the short-lived weeds that grow only for one season and then die out. The leaves of grassy weeds look like the actual grass blades. They also produce one and are similar to plants in the manner that they come out one leaf at a time. These are not easy to distinguish against the plants. The most common examples for these are foxtail, crabgrass, and quackgrass.

Grass-like weeds

These are even named to be similar to the grass, so it does imply that they look quite like the grass. That said, it is still easy to distinguish them from the actual grass. The blades of grass-like weeds are hollow and shaped as tube-like or maybe triangular; they are not flat like the grass blades. This makes them stand out in appearance.

How To Prevent The Lawn From Weed?

We have all heard about how the prevention is better than cure. It is a lot easier if you prevent your lawns from getting the weeds than to work towards removing the weeds. Your lawn will be a lot healthier and easy to maintain if you work towards preventing the growth of weeds itself. There are a lot of ways in which you can avoid the occurrence of weeds. Let us look at some of the methods that you can easily follow:

Mow The Lawn In The Right Way

The prevention of weeds can be prevented from a step as early as mowing. You need to mow the land at a higher height to start with. Weeds are plants, and like all plants, they too need sunlight. When the next time you mow, raise the height of your small yard lawn mower so that the grass that grows is taller. The taller the grass, the thicker will be the shade, and the soil will not get enough sunlight for the weeds to grow. Lesser the sunlight, lower are the chances of the weed to become.

Water It Nicely

For your lawn to be able to compete against the weed, it needs stronger and deeper roots. You must water your lawn by achieving that. You need to water deeply and infrequently as it helps to develop deeper roots for your plants. Frequent and shallow watering strengthens thin roots which can be easily uprooted or distraught during heat or drought. This uprooting will give the weeds the space to grow out, which we need to avoid. Hence, it is necessary to water deeply.

Well-Fed Lawn

Just like for our body needs to be well fed to combat diseases, your lawn needs to be fed well with all nutrients and the best lawn fertilizer to combat weeds. If you use good fertilizers and fertilize your lawns regularly every 6 to 8 weeks, then the lawn will have more strength to resist the growth of weeds between them. A thick lawn which is lush with growth helps to cover all space and leaves no space for the unwanted plants to grow in between.

Use Weed Preventer

Another temporary method for stopping the growth of weeds is to use the weed preventer. These come in granules, which can be spread around the lawn, and it will stop the growth of weed for around three months. There are some weed preventers which come with a dispenser which makes spreading the granules around the lawn very easy for our convenience. There is an option to get the weed preventers along with fertilizers so that the other crops are nourished.

Lawn Fertilizer With Weed Control

There are lawn fertilizers that help to keep the lawn well-nourished and fertilized, and there are also some best lawn fertilizer options that come with weed control in it. Spreading these will help to fertilize the lawn as well as keep the weeds from growing out and causing any more harm. The fertilizers will make the lawn dense, and there will be no place for the weeds to grow, and for the rare weed occurrence, the weed control will keep them at bay.

These are the few ways in which the weeds can be controlled from growing, and the lawn can continue to be healthy without any weed presence. Taking precautions can help you prevent all the more efforts and also keep your lawn away from any more exposure to any more chemicals.

Factors To Look For In The Best Lawn Weed Killer

When you decide to use the best lawn weed killer, you will need to make a choice very smartly and choose the product after a lot of considerations. This product needs to be applied around your plants and in your lawn. Any miss in choosing the product will lead to a poorly maintained lawn, which is not something you would want. Below are the factors, explained in brief, you will need to consider before you choose your weed killer:


You would have to start with finding the coverage that you are expecting from the lawn killer. The size of the package is not the sole determinant for this. You need to check how much water needs to be mixed to make that weed killer work. Some are concentrated, and a little mix works on the massive area while some are diluted and they cover a small space even with good quantities. So you need to check the mixture and then choose the best lawn weed killer.


When you spray the weed killer, you are spraying it on the lawn, and hence it also impacts the grass on the lawn. Most people would want to choose a weed killer, which causes zero to the lowest impact on the lawn aside from the weed. You would wish to see an entire lawn after the weed killer has killed the weeds. A selective herbicide would do the job for you; however, in this case, if you choose perennial weeds, they will impact your plants too.

Residual Effects

Too much of anything is bad and same is the case with the best lawn weed killer as well. When you use the weed killer, it might affect your soil and inhibit the growth of future plants on that soil. The best weed and grass killers are available which have no impact on productivity. However, one must always consider that any chemical used again and again will ruin the quality of the soil and the herbicides are no different.

Area Of Use

One more important consideration that needs to be done when buying the best lawn weed killer is the area at which the growth has happened. Here we don’t just mean the square feet of the weed-covered area but also the type of space. Whether it has grown around the edges with shallow roots or the very heart of the lawn or patio. Each of these areas will have a differential treatment and approach, and hence, it is imperative to consider the same.

Effects Of The Weed Killer

How do you expect your weed killer to work? There are weed killers with chemicals which kill the weed slowly while there are some that kill the weeds in a day or two. There is a variation in the destruction method too. You need to decide based on the severity of the weed growth and also the impact you are ready to see on the vegetation around.


The emergence of the weed killer would determine the time at which you would want to use the product on your lawn. There are different products if you’re going to use them before the weed is generated which are used in the pre-emergence stage and there are some which are applied after the weeds are on the lawn to kill them which are termed as post-emergence products. When you plan to use these is something you would need to evaluate and decide.


The products which are used on the lawn before the weeds to prevent the weeds from coming on are the pre-emergent. These can also be mixed with the fertilizers and applied on the lawn so that the land gets fertilized as well as is ready for the protection against the weeds. The weeds are stopped from growing with the help of pre-emergence weed killers. When you know about the annual influx of weeds in your lawn, you can be prepared and prevent it from using these.


The post-emergence weed killer is used typically when you already have an enormous weed growth and need to deal with it. This weed killer works on established extensions as they are sprayed on the weeds. They will infiltrate the weeds and kill them from within and cause them to die. Hence, weed growth will be removed.

Working Methodology

As we saw the weed killers divided based on time, these can also be classified based on the working methodology. In this way, the weed killers can be divided into two types based on how they work and the time they take to resolve the weed problems for the lawns. You can choose the one depending upon the situation and needs. Below are the same explained in brief:

Contact Weedkillers

As the name suggests, these contact weed killers work based on the contacts. It will work only if it comes in connection with the weed. It kills the weed that it comes in touch with and does not work beyond that. It kills the visible weed only and doesn’t work on the weed below the soil. So it does not kill any weeds from the roots, and it cannot be used for deeply rooted weeds. It shows the results in a day or two.

Systematic Weed Killers

These work more in-depth and are opposite to the contact weed killers. These systematically entire the soil and kill the weeds from their very roots. They remove the complete existence, and these herbicides take time to work. The results can be seen only after two to three weeks. They work slowly, but they also work deeply. If you have a profound presence of weed on the lawn, these are the ones you’d want to choose.


When choosing a weed killer, do not select any brand without checking. You would need a brand that works effectively and has already been proven to be good. Taking a risk is not advisable. If you are choosing an entirely new brand, do research and read all the reviews to get a better understanding of the product. The end consumers always give honest reviews, and that will help you see clear expectations.


Everyone works at a budget. Even if money is no problem for you, it is wise to pay the correct and fair price. Don’t choose the product randomly based on the price. List down what you need, compare and decide on the cost by selecting the one which gives you the best cost-benefit analysis result.
