The question now must be: “How can I kill off every remnant of weed in my garden?” Well, here are seven of the best weed killers we believe will let your precious plants thrive to the sunrise.

How to Pick a Good Weed Killer? – A Buyer’s Guide 

We cannot stress enough how important finding the correct weed killer is to ensure your lawn and your plants are healthy. However, the internet will provide you numerous suggestions that will make it harder to find the right weed killer for you. Thus, we will provide you some factors to consider when purchasing your weed killer. These factors will drive your buying decision to the right product for you. 

The Types of Weed Killers

Herbicides (another name for weed killers) are classified into two types: Contact (1) and Systematic herbicides. These two types of herbicides will directly impact the effect it will have on your lawn. We will discuss each one for it to be clearer for you. 

The Contact Herbicides only kill the part of the weeds it meets. This means that it might not be able to reach the deeper parts of the roots. Further, killing the plants would eventually be harder since it will tend to grow back easily. The advantage of using contact herbicides is the speed of killing the weeds. You will most likely see significant progress in less than a day. 

On the other hand, systematic herbicides systematically reach the soil’s deeper parts to inflict poison on the roots. This strategy will immediately remove the weeds from that part of your lawn. However, systematic herbicides will eventually take slower. The effect speed will depend on the soil you use as well as the product you are using. 


In most herbicides, price matters significantly. Most products reflect their price through the chemical quality in their herbicide. Thus, you will most likely need to invest more money for an effective herbicide to kill the weeds effectively. 

Cheaper products will tend to have a weaker concentration of chemicals; some would have an intense concentration that could kill the plants in its path. Cheaper products also mean that the chemicals are not waterproof. You will need to reapply your product when the rain is over. 

More expensive products will tend to offer more benefits than others. They most likely possess all-natural elements to avoid any unnecessary complications to your health. Expensive products will also entail the chemical being more effective and efficient on the weeds. 

Eliminating weeds should be an investment on your part. You are eliminating weeds with the best solution possible, so it would not bother you anymore. 


Size also offers a dramatic effect on your buying decision. The size of your herbicide must also be tangential to the size of your lawn. There are many products out there that offer a gallon of herbicides. This gallon caters to lawn owners with a large portion of land to take care of. Investing in a gallon of herbicides may be a waste of money if you are only taking care of a smaller portion of land. 

On the other hand, lawn owners with bigger yards cannot purchase a herbicide designed for smaller ones. You must invest in a larger quantity of herbicides to take care of a larger portion of area.  

Logically speaking, a larger herbicide will also mean a more expensive price. Thus, be prepared to shoulder the cost of fully removing weeds from your garden. 


This should be a non-negotiable for you. As stated before, a waterproof herbicide will ensure that your product can withstand all the things Mother Nature will throw at it. As always, waterproof herbicides will tend to cost more than others. However, this is a price you should be willing to pay if you want those annoying weeds out of here. 

There are many more factors you can consider when purchasing your weed killer. There are many more factors that you can think about to ensure that you have the best herbicide in your hands. However, if you are still unsure of what herbicide to purchase, contacting a professional may seem the best option. 

Contacting a professional will ensure that you receive professional advice for your lawn. In this way, you will not need to guess which herbicide is best for your lawn. However, you will need to pay this consultant a small monetary compensation to pay for the hours he used to diagnose your lawn. Nevertheless, this is a price that is worth paying to provide you the necessary information that you might not get elsewhere. 


We showed you seven of the best herbicides you can use for your lawn. Note that there will always be pros and cons in every product that you will use. Thus, try to find the balance between your needs to get more of what your lawn needs. We also showed you some factors to consider when deciding what herbicide you would want to purchase. 

One thing is for sure: taking care of a lawn is a hard thing to accomplish. To take care of your lawn, you will need the best of the best for it to thrive. Most of the time, the lawn’s beauty will require moving the things that make it ugly.
