Whether it is grass or weed, each and every one of them requires certain conditions for growing. So, you need to be careful so that you don’t mistakenly enhance the weed growth instead of the grasses. To make sure, you don’t do that, here are small tips on how you can ensure proper grass growth and prevent the weeds from growing more.

Optimum Conditions for Grasses to Grow

Lawn Mowing Ways

This includes grasses of which height you’ll decide to keep on your lawn. Because the mowing height might have a direct result on how healthy your lawn will be. If you keep the grasses on your lawn too short, the weeds will be exposed to the sunlight, and that is definitely something you wouldn’t want! So, keep the grasses on your lawn taller.

Water Heavily

Weeds normally suck out too much water from the lawn, leaving it dry! So, in presence of weeds, your grass wouldn’t get enough water which is one of the most important factors in growing grass. Proper practice of watering will not only nourish the weeds on your lawn but will also serve as a factor that slows the growth of weeds.

Ensure Proper Aeration in the Soil

Compact soil is a great place for weeds to grow. So, make your soil loose which will ensure proper air, water, and nutrient circulation. Thus, your grasses will be able to get enough nutrition to grow. Healthy soil is the biggest enemy of the weeds and the greatest ally to the grasses. So, you know what to do now!

What are the can Grass Seeds that Kill Weeds?

Okay, now comes the most important question! In this section, I’ll be answering just what you want to know!

First things first, here’s a little pro tip: If you want better results, uproot the most significant weeds from your lawn, and then get into planting grass seeds.

There are actually a few types of grasses that’ll do the job. However, grasses grow seasonally and climate-based. Grasses that are more tolerant to heat, or Warm-Season grasses, and grasses that are more tolerant to cold weather or low temperature, or Cool-season grasses. Down are the few types of grass that you can use to kill weeds:-

Grasses that Grow in Warm Season

Warm-season grasses basically grow better in warm and humid a temperature which makes them ideal to plant in Summer. They are more tolerant to heat, but they don’t do well in a cooler environment.


You’ll see this grass growing pretty well in very hot areas with longer and hotter days. That’s because it has a very high tolerance for heat and drought. It has bigger leaves and a rough texture. In the Southern region, this grass species requires lower maintenance the entire summer.

Bermuda Grass

Aside from its exceptional tolerance for heat, it can also survive excellently under high foot traffic. Though you might want to supply a huge amount of nutrients, proper water and air circulation, and sun exposure. So, it’s kind of a relatively high-maintenance grass than the previous one.

Buffalo Grass

This grass, unlike the ones I’ve discussed earlier, can also grow well in diverse climate conditions. You can even see it growing well in relatively colder weather. Though this is not the case always, in excessively cold weather, it turns brown just like other summer grasses. But if you want it to grow well, April-May is the best time to do so.

Centipede Grass

Pretty interesting for a name, huh? But trust me when I say this, this grass is your choice if you live in a place with high temperature and with low maintenance. It’s much more popular with the working-class people who don’t have much time to spare for their lawns. It grows in abundance starting from spring till the time it gets full sunlight.

St. Augustine

If the question comes as to which grass can tolerate the most heat and humidity, St. Augustine got no rivals. They grow very quickly and have unique blue-green blades on the leaves. Its high growth rate, invulnerability to saltwater, and high spreading rate make it an ideal choice if you want to get rid of weeds on your lawn.


Last but not the least, among the summer grasses, this species is the most ideal for killing weeds. It’s tough and requires low maintenance, and high resistance to heat, drought, and foot traffic. It creates a very dense grass surrounding that chokes out the grasses, not letting them intake any nutrition, while you don’t even need to put on much effort into it!

Grasses that Grow in Colder Season

Cooler season grasses, unlike the warmer season grass, are less tolerant to heat but thrive better in colder weather. If the temperature goes up a certain level, they turn brown and eventually die. So, if you have somewhat colder weather where you think the grasses listed above won’t survive, then these grass species are the ones you need to look into!


You’ll find this grass very commonly in the United States. It’s a versatile grass that can tolerate any weather and water condition. Though it is very simple to grow, but it can be damaged by foot traffic. So, be sure to know what’s at stake while choosing this grass.

Kentucky Bluegrass

If you want to have an ideal lawn, this is the species you should go for. It has a very rich green color that will make your lawn look very lively. However, there’s a catch! It needs very high maintenance and can be very difficult to grow. You’ll have to water it regularly as it has a very thin rooting system.

Perennial Ryegrass

Last but not the least, Perennial Ryegrass is, in fact, among the cold-weather grass, the best one for killing weeds. Because of its high generative ability, it grows pretty fast and will cover your entire lawn in no time at all. They grow well in cooler to mild warmer weather.

This is all the grasses you might want to look into if you want your lawn out of weeds and full of grass at the same time. Though all of these grasses work very well, but if you ask my personal opinion, I’d say the Zoysia grass is the most effective and the best grass species to choose if you don’t want any weeds on your lawn. The rest is your decision.

Final Words

Can Grass Seeds That Kill Weeds? – List of Grasses that Overwhelm Weeds in Your Garden. Finally, before planting those grass seeds, make sure you’ve pulled the significant weeds first. I know, I’ve already mentioned it once before, but since I’m doing it again, that implies how important it is. You might ask why is that? This is because, if you don’t uproot those weeds first, they might inhibit the seeds from getting enough water.

Water is very crucial for germinating grass seeds. Since they have no way of getting enough sunlight, the only way for them to get nutrition is from the water in the soil. Bigger weeds tend to suck a huge amount of water from the lawn soil which might create a water shortage for the growing grass seeds.

Now you know all about the grasses that might make your lawn free from weeds and prevent them to grow back! Right now, all you need is to decide which one would work best on your lawn according to the climate condition you’re having, the look you want to have on your lawn, and the amount of effort you’re willing to put into your lawn.

So, good luck with what you choose to do, and be sure to share your experience with us! We’d love to hear back from you!
