11 Best Weed Killers for Lawns Reviews in 2022

Those of you who have a large backyard most likely have at least a few plants grown back in there. But no matter how much care you take, some weed will also grow along with these plants which becomes an even bigger issue for larger lawns. To get rid of such weed from your lawn and backyard, you can consider using something like the best weed killers for lawns which have been chosen as per these factors:

  • Liquid Volume: Because you will need a lot of weed killer for larger sized lawns, checking the total liquid volume offered by your weed killer is quite important. While smaller options might offer 16 or 32 liquid ounces, larger options can have 128 liquid ounces or even more quantity of weed killer for large sized lawns.
  • Coverage Area: Another factor to consider for making sure that you can cover a large field with your weed killer for lawns in the coverage area rating. This is due to the reason that a large coverage area rating like up to 15000 square feet or up to 25000 square feet is much more ideal for large sized lawns than smaller coverage area rating like up to 3000 square feet.
  • Rainproof Time: You can find many weed killers for lawns that are rainproof and do not wash away during rain. However, these weed killers need some time to try, which is known as the rainproof time. While budget options can take up to 4 hour long or even up to 6 hour long to become rainproof, high performance options have a rainproof time of up to 2 hour long which is much lower.

While these are some of the most important factors, there is still much more to consider while considering the best weed killers for lawns. Hence, all the best weed killers for lawns given here also have their important features and specifications stated with them.

Buying Guide for the Best Weed Killers for Lawns

Weed infestation is one of the biggest issues that you will face while working on large-sized lawns. Not only does weed and other such plants ruin the looks of your lawn, but it can also affect the health of other plants.

Because of this, it is highly recommended to use one of the best weed killers for lawns stated earlier in your lawn. Thanks to their aspects and factors described earlier, you can easily pick the right one and get the most out of them. To help you understand even further about weed killers for lawns, here is a complete buying guide for the best weed killers for lawns:

1. Liquid Volume

Whenever you are buying weed killers for lawns, you should first check the capacity or the liquid volume of your weed killer. This is due to the reason that if you have a large-sized lawn, you may need a lot of weed killer for the same.

As for the liquid volume or capacity ratings that you will find out there, it includes options like 16 fluid ounces, 32 fluid ounces, 128 fluid ounces, and even higher where having more liquid volume is always recommended for larger lawns. In some cases, you may also find solid weed killers which will have their capacity given directly in pounds like 10 pounds or 15 pounds. Similar to liquid options, having a more solid weed killer with more weight is also recommended.

2. Coverage Area

Even though having more weed killers is always great for larger lawns, not all weed killers are the same. Due to this, two different weed killers with the same liquid volume or capacity might not be able to cover the same lawn area.

Therefore, checking the exact coverage area offered by your weed killer is highly recommended. Regarding the same, you can find coverage area ratings like up to 2000 square feet, up to 5000 square feet, and even up to 25000 square feet. Such weed killers with high coverage area ratings are perfect for heavy-duty usage in large-sized lawns.

3. Rainproof Time

If your weed killer is not waterproof, it will simply wash away whenever it rains in your area. As a result, many weed killers are rainproof and do not mix with water easily. However, since these are liquid weed killers, they need some time to completely dry off before they can become rainproof. For the same, you can find different rainproof time values which can include options like up to 6 hours, up to 4 hours, and even up to 2 hours in some cases where having a shorter rainproof time is always recommended.

4. Solution Type

Apart from checking these specifications and performance metrics of your weed killer, you should also check the solution type that you are going for since it will affect your application experience. If you are in the market for a new weed killer for lawns, then you will primarily find liquid solutions. But not all liquid solutions are the same since some are ready to use solutions that can be used right out of the box.

On the other hand, some other weed killers for lawns are also concentrates which need to be mixed before you can start using them. As for liquid weed killer alternatives, you can also find solid weed killers for lawns. These are generally more powerful but are harder to use because of the lack of a spray.

5. Shelf Life

In case you do not have a large-sized lawn or backyard, then you are most likely going to end up with a lot of extra weed killer especially if you are going with large capacity options. To ensure that you can use this weed killer later on when needed, it is highly important to go with a weed killer which has a long shelf life to ensure that it does not go bad. Even though most weed killers for lawns offer a shelf life of up to 1 to 3 year long, you can also find some options with up to 5 year of shelf life which should be more than enough for most people.

FAQs for the Best Weed Killers for Lawns

1. How regularly should you use a weed killer for lawns to prevent weed infestation?

While it is recommended to use a weed killer right before you plant new plants and vegetation in your lawn, you can also use weed killers whenever you see weed growing in your lawn. In most cases, one application of weed killers for lawns should last for the whole season without any issues.

2. Is it better to use solid weed killers or liquid weed killers in your lawn?

In order to use a concentrated weed killer, you need to mix it up with water in a separate container. Since these are concentrates, you may have to use your own spray bottle which is something to consider if you don’t have one with you.
