How To Kill Weeds Without Killing Grass? (And Prevent Weeds From Growing)

Whether you spend a lot of time doing it yourself or you hire a firm to manage it, having a beautiful lawn has a cost.

It depends on how much time you want to put into it, if you can do it well or if you need help, and whether you like doing it.

Your objective is the same whether you do it yourself or hire assistance: to have a lovely, green lawn free of weeds. It all comes down to prevention and having a plan for getting rid of weeds when they emerge.

In this article I’m going to explain how can you kill those weeds without killing the grass and how can you actually prevent weed from emerging in your garden. Let’s start!

How To Kill Weeds Without Killing Grass?

Use A Selective Herbicide

You want to pick a weed killer that has been specifically designed to kill weeds without harming your existing grass. Because it is selective, not every plant it is applied to will perish. The more popular selective herbicide is 2,4-D.

When used correctly, it has very few dangers and is quite effective in eliminating weeds without harming your grass. The method that a selective herbicide works is by penetrating the weed’s leaf and altering how the plant processes nutrition. It literally ages and grows till it dies as a result of it.

Although they can practically start working overnight, selective herbicides often take 4–14 days to provide extremely noticeable benefits. It effectively kills 99 percent of broadleaf weeds at the root, ensuring that the same weed won’t be an issue in the future.

Pulling The Weeds By Hand

Pulling the weed out of the ground by the root and throwing it in your compost bin, either by hand or with a removal tool, is an immediate fix. To combat this, weeds purposefully rip at the soil’s surface so that their roots can continue to grow.

To completely remove a weed from head to toe, use a flathead screwdriver, a ford, or a specialized instrument made for weed pulling. Wearing gloves is strongly advised because certain weeds have spiky surfaces that can seriously sting.

It’s crucial to keep in mind that if you remove the weed by the leaves or steps, it will snap. You may be sure that weed will come back in a few days if the roots remain intact. You must thoroughly eradicate the weed from the ground with the equipment you employ for it to be eliminated.

Do this for dandelions when the heads are still yellow because once they become white, movement will cause them to distribute seeds wildly. If your kids want to throw them into the wind, take them to the neighborhood field rather than your yard!

Mowing Properly and Regularly

In the spring, your lawn needs to be cut every week, and in the summer, at least once every ten days. Instead of using a bag, mulching the grass back into the lawn helps disperse grass seed and thicken the turf. Each year, you should sharpen your blades, and you should never cut the grass more than a third of the way.

Remember that when you mow your lawn, you also mow the weeds, which eliminates them from being visible for a few days, but they will try to reappear since their roots are still active.

Re Sod Your Lawn

For lawns that have been ignored for too long, this is the absolute worst-case situation. You might want to think about hiring a landscape professional to come in, tear down the sod, regrade with dirt, and then re-sow the area if weeds have totally taken over and there is little grass remaining to fight them off.

This can cost up to $2.20–$4 per square foot, depending on yard access and sod disposal costs in your area. Unless all other methods have been exhausted, avoid re-sodding.

How To Prevent Weed From Growing In Your Yard?


Weeds thrive in arid climates because they require little water to develop effectively. Giving your grass a chance to thrive and defend itself against weeds requires that you irrigate your lawn for 30 minutes, at least three times every week.

Fertilize Your Lawn Every Season

Even though many countries don’t have access to the majority of “pre-emergent” weed control methods, utilizing a high-quality fertilizer will provide your grass with the nutrients it needs to grow.

Aerate Every Year

One of the nicest things you can do for your grass is aeration. Aerating hits the nail on the head because weeds enjoy dry, compact soil. It reduces soil compaction, encourages ventilation, and improves soil water retention. Every fall, you ought to aerate your lawn.

If you aerate in the spring, you expose your lawn to early-season weed germination, so you have to maintain an annual fall aeration schedule.

Overseed Every Spring & Fall

Your lawn grows and eventually dies because it is an organic substance. Spreading grass seed all over your land is the procedure of overseeding your lawn. Use the same variety of grass seed that your lawn is currently made of when you plant for the best results. Give your lawn enough of water, and it will be grateful and free of weeds!

Closing Words

Weeds steal nutrients from your grass and if left unattended will eventually take over, so it’s crucial to get rid of them. Weeds have a tendency to take over and spread. Once they have your grass, they will move on to the nearby lawns in your neighborhood, and the situation will only get worse.

You may enjoy a gorgeous lawn without spending all of your free time on it, you can get fantastic results for a reasonable price, and you can eradicate weeds without destroying the grass! All you have to do is read this article carefully and follow all the advices and tips I have written for you.

If you do that, you are guaranteed a beautiful green yard without any weed on it!
