Weeds are renowned for being tough to eradicate. In lawns, weeds compete with grass for available nutrients, so they will completely take over your lawn if treatment is not instantly implemented. Using weed killers is one of the best approaches for getting rid of weeds in the yard. However, some weed killers contain chemicals that destroy your lawn. Therefore, this article will give you some best weed killers that won’t kill grass and their features before you select one for your need.
The reason to get rid of weeds
It is easily noticed weeds are in the garden, but if they are not eradicated, they can absolutely overrun and destroy your crops. Besides, for their survival, they compete for light, moisture, and nutrients with crops, which can have a negative impact on harvest yields. In addition, some weeds are difficult to kill. Field bindweed is a specific example. It develops a dense network of lateral roots under the soil even when there is no foliage showing. Furthermore, their roots may survive in the soil for up to 50 years before sprouting. Another reason is that weeds might potentially be disease and insect hosts. Additionally, they easily reproduce from any part of the root system or from wind-blown seeds and can handle the cold, the sun and the shade condition.
What eliminates weed and not grass?
Non-selective herbicides are used for large weed treatment as they eradicate any green, growing plant, whether it is a weed or not, while selective herbicides are tailored to target only certain weeds. The majority of broadleaf herbicides are a perfect choice to deal with these weeds while not harming your grass since they are systemic and selective to kill these weeds only.
What to know before you purchase weed killer that won’t kill grass
There are numerous weed killers on the market that effectively eliminate weeds, but some of them have a negative impact on your lawns. Therefore, take a few minutes to learn some factors before selecting the right product for your need.
Types of weed killer
Two main types of weed killer available for weed control are selective and non-selective.
Selective weed killers are designed to eliminate a specific type of plants or weeds, thus, they are an ideal option for those looking for one that is safe for the rest of their lawn. However, different type of selective weed killer kills weeds in different ways. Some weed killers kill weeds before they sprout, while others eliminate those that have already grown above ground.
Nonselective ones, on the other hand, kill weeds and plants they come into contact with. Therefore, it is of vital importance to pay attention to using a nonselective weed killer for weed control to avoid accidental contact.
In general, it is advisable to use weed killer when the temperature is between 40 and 90 degrees, which means that in some places, it is applied in spring, summer or autumn. However, a weed killer that does not have heat restrictions is a good idea for those who need to get rid of weeds in more extreme temperatures. Besides, an effective alternative for weed killers is weed eaters that work well in smaller areas or when there is a concern about sudden temperature changes.
Some highly concentrated weed killers require you to add water to dilute them before use as they can cause damage to grass or flowers if they are highly concentrated. In contrast, some ready-to-use weed killers allowed you to apply them directly on treated areas. Additionally, a spreader might be a helpful device if you are covering a large area.
What to look for in the best weed killer that won’t kill grass
It is simple to pick up a weed killer to deal with your problem, but some of them may give you a disappointing outcome. Thus, some qualities in a weed killer you need to consider when choosing the best weed killer that won’t kill the grass.
Weed killers that won’t kill grass are available in organic and non-organic formulas. Organic weed killers use natural ingredients such as clove oil, vinegar, salt and essential oils to eradicate weeds, which makes them safe for kids and pets.
On the other hand, non-organic selective ones consist of a variety of chemicals and phenoxy herbicides, including dicamba, clopyralid and mecoprop-P that can be dangerous if ingested. Thus, they should be kept away from animals and children. Both types of weed killers are efficient for weed eradication, however, non-organic ones are often fast-acting. Some non-organic ones effectively eliminate and prevent weeds, even before they appear above ground.
Besides, glyphosate is an active ingredient in non-selective weed killers that can completely kill grass and other plants, therefore, you should not pick up them to avoid harming your lawns.
Weed killers often come in liquid and granular forms. With a liquid option, you simply apply it in treated areas. While some require you to add water to dilute them, others are equipped with a spray nozzle and are ready to use.
Granular or powder types are a little less common than liquid types, but they are also powerful weed killers. They often include chemicals or other ingredients that allow them to adhere to grass without harming it.
The size of liquid weed killers ranges from around 32 ounces to several gallons, therefore, depending on your treatment areas, you select the right product. A gallon is recommended to deal with weeds in large areas while a smaller size is suitable for getting rid of weeds in small areas.
With granular or powder options, you easily find bags weighing from 5-10 pounds to 40 pounds. If you use a weed spreader to apply this type of weed killer, a larger bag may be a good idea.

The best way to use weed killer that won’t kill grass
You can use weed killers in different application ways to deal with your weed problem, but the improper application can break their effectiveness. Thus, it is essential to know some considerations before you spray these chemicals in your yard.
The most common method of spraying weed killer is to dilute it with water in a spray bottle, which enhances the lifetime of your weed killer and makes the product easier on the environment.
Another important consideration is climate conditions. You should not use the chemicals during drought conditions as they can harm your lawn if it is too dry. Because the chemicals take time to work, it is advisable to apply when there is no rain expected for at least six hours.
