Kill Weeds Not Grass: How To Do It


When it comes to successfully killing weeds while protecting your lawn, there are many different methods and products on the market.

While some approaches may seem easy, it’s important to look closer to ensure you are not inadvertently harming the grass you worked so hard to protect.

Here we will discuss some of the best methods for “kill weeds not grass”, from liquid or granular chemicals to warm and cool-season grass herbicides. Whether you want an organic or chemical approach, there is something here for everyone who wants their lawn to look healthy and weed-free.

What to use that kills weeds, not grass?

You can choose between liquid or granular chemical weed control options, each with pros and cons. Liquid products are much faster in killing weeds, usually within a few days. However, fast-acting chemicals, such as Glyphosate, can also harm grass.

When spraying weeds with Glyphosate, nearby grass could also be harmed due to its solid herbicidal properties. Hence, it is recommended that non-selective herbicides be used on ornamental beds, sidewalks, or patios where weeds have accumulated.

Spectracide comes in liquid and granular forms, but the granular version is easier to apply and safer for your lawn. The granular type contains Dithiopyr, a pre-emergent that prevents new weed growth. Only use enough of the product to target weeds, not other plants, and keep in mind that the purpose of using weed killers is to allow your lawn to grow healthy.

We have gathered two seasonal herbicides designed to kill weeds not grass, making them ideal for eliminating weeds from your lawn. To make it easier for you, we have categorized these herbicides into warm and cool-season types depending on the plants they work best on.

Warm Season Grass Herbicides

Weeds, such as broadleaf, typically grow well in warm weather during the spring and summer but die off in the fall when it gets colder. To kill weeds not grass, you can use an herbicide made specifically for seasonal weeds during the warmer months, such as Celsius WG or Certainty herbicide. This will help you target the broadleaf weeds without causing any damage to the grass.

Cool Season Grass Herbicides

Most weeds prefer warmer weather, while some, like Rescuegrass, Clover, and Poa annua, do well in cooler environments. Fortunately, you can use weed killers like Tenacity herbicide or sledgehammer to eliminate these cool-season weeds without harming your lawn.

How To Kill Weeds Not Grass – In Conclusion

Removing weeds without damaging grass or plants requires good planning, the right products, and patience. The number one rule to remember is to make sure whatever you do addresses the weed problem itself, not the symptoms of it.

It is worth considering investing in more specialized and selective weed killers who target weeds specifically while leaving grass unharmed. These measures will help ensure a healthier-looking lawn year-round, with fewer weeds. That’s why our call to action still stands; people should get weed killers that kill weeds, not grass.
