Now that you have read through our selection of five amazing weed killers for large areas, you will be in a good position to begin purchasing your weed killer. After all, this list will have given you an impression of some of the features to look out for when searching for a weed-killing formula. 

However, to make things easier for you, we have decided to list some of the primary elements that you should consider when shopping for a successful weed killer.

If you have these qualities in mind while you are shopping, you will be able to find the right product for you. We urge you to bear these features in mind when you begin shopping so that you can find the most efficient weed killer for your needs.


Weed killers are not particularly expensive items to buy. In fact, they can be bought quite reasonably. Weed killers tend to cost between $15 to $25. Most people will want to have an effective weed killer at an affordable price.

Thankfully, it is possible to achieve both. If you are not willing to spend a lot of money on a weed killer, you can still buy good brands for small prices. If you are willing to spend more money on weed killers, you can find some that are considerably more expensive. 

If you are hoping to find specific features in your weed killers, they will probably set you back more money than more basic products. For instance, if you want natural and organic weed killers, these will probably be more expensive than those that do not have these ingredients. 


Most weed killers are created to be fast-acting. This means that they can save your garden quickly and you will not have to worry about them taking ages. However, the speed with which weeds can be killed will significantly vary between products. Some deliver results in only a few hours. 

On the flip side, many weed killers take weeks to completely finish the job. If time is of the essence and you want to remove weeds urgently, you will probably be looking for a fast-acting product.

Most weed killers will list the amount of time that they take to work on their packing, so be sure to check this information out if you desire a speedy product.

Of course, the speed with which a product will actually work will depend on your garden and the application of the formula. 

Ease Of Application

Want to reduce the amount of time you have to spend getting rid of weeds? Fortunately, lots of products on the market are accompanied by tools that make applying their formulas much simpler.

For instance, the Spectracide weed killer comes with the AccuShot. Meanwhile, the Ortho and Roundup weed killers feature wands that are designed to make the application not only more straightforward but also more accurate.

This will likely be of particular concern to you if you have limited mobility or are older in age. 


If you are looking for weed killers that will cover a large area, you will want to think about the amount of coverage it has. To find this out, you will want to check how much formula is contained within the product.

The more gallons or liters contained within a product, the more weed killer you will have. This information can easily be found on the product’s packaging.

If you need a lot of coverage, you may need to invest in multiple packets of weed killer. This will significantly impact the price of the weed killer. If you are hoping to cover a large area with weed killer, you will need to be willing to spend more money on products. 

Water Resistance 

Numerous weed killers have been made to resist water. This is to ensure that they remain effective even when the weather is rainy. This is a really valuable feature, particularly if you live in a state with lots of rain or if you are using it at a particularly wet time of year. 

However, some products take longer than others to become waterproof. With some formulas, you will have to wait for multiple hours until they can resist water. This will mean they are less effective in wet weather.

Therefore, if you plan on applying weed killer to your garden during a wet season or during rainy weather, you should search for a product that develops water resistance quickly.

It is best to find weed killers that do this in less than an hour and preferably as quickly as possible. 

Kills Roots

One of the main positive aspects of weed killers is that they tend to also target the roots of a weed, which will prevent them from quickly returning. This can save you a lot of time, effort, and money, since you will not have to keep applying weed killer to the same spots.

The degree to which formulas attack the roots will differentiate between products. If you are looking for a weed killer that eliminates the root, make sure that it lists this as a function on the packaging. 


Weed killers frequently contain strong harmful ingredients. If you have pets, these chemicals could endanger your animals. If so, you will have to stop your pets from going into your garden when you apply weed killers.

Despite this, you can get weed killers with more gentle ingredients, such as the Pet Safe item on this guide. Some customers will also be interested in attaining weed killers with organic ingredients. 

Best Weed Killer For Large Areas-FAQs

What Is The Best Weed Killer?

To be honest, there is no one clear answer to this question. Every professional weed killer will have its advantages and disadvantages. Despite this, all the products on this list are effective options.

You will likely prefer some choices to others. This will ultimately be dependent on personal preference and what features you want to be present in your weed killers. 

Which Weed Killer Is The Fastest?

Like the previous question, this is somewhat subjective. As we mentioned earlier, the speed with which a weed killer will work is one of the most essential features.

You will probably want to purchase a formula that begins to work quickly, namely within a few hours, and finishes working within a couple of days. 

Do Homemade Weed Killers Work?

In truth, some homemade weed killers are successful at removing weeds. On the other hand, you should consider that there are disadvantages to using homemade formulas.

For example, some of these formulas can be quite harmful to your garden. Furthermore, homemade weed killers can be quite slow to act. Professional weed killers are crafted specifically to kill weeds, making them very effective options. 

Does Vinegar Kill Weeds?

Yes, vinegar can be used to kill weeds. It is, in fact, used in some of the products listed above. Vinegar contains acetic acid that can be deployed to dry out weeds. However, some types of vinegar can also damage your grass.

Vinegar can impact the pH balance of soils, making it potentially quite damaging to your garden. In addition, vinegar often fails to get to the roots of the weeds, meaning they can easily grow back.

Consequently, you are better off using weed killers that have more complex formulas, since these have been designed to effectively remove weeds from your garden. 

Hopefully this has helped your quest to find the best weed killer for large areas and you get rid of those pesky weeds once and for all!
