Will Overseeding Choke Out Weeds?

Overseeding your lawn will thicken the grass, helping it resist future weed invasion. However, it is best used on a lawn where the weeds are currently dormant or have recently been killed. Spreading grass seed on a weedy lawn won’t do much good. Weeds that are actively growing in your grass will steal water and nutrients from grass seedlings, causing them to struggle and die. For best results, attack lawn weeds with a weed killer, then overseed to create a healthy lawn that prevents weeds from returning.

How Does Overseeding Help Prevent Weeds?

Overseeding your existing lawn with new grass seed fills in bare spots and contributes to thicker grass throughout the lawn. A thick grass lawn without bare spots shades the soil below, depriving weed seedlings of sunlight, killing them. Not only that, but thick growing grass pulls moisture and nutrients from the soil first, before weed seedlings can get to them.

  • Overseeding contributes to a thicker lawn.
  • Bare spots that have been overseeded with grass are less prone to weed invasion.
  • Lawns thickened by overseeding prevent weed seedlings from receiving sunlight and nutrients, smothering them.
  • Regular overseeding maintains a thick, weed-resistant lawn without herbicides.

Grass plants, like all plants, weaken and die naturally over time. By overseeding you replenish your lawn with new grass plants. This constant replenishment keeps your entire lawn thick enough that it continues to smother new weeds. This reduces the need to use chemical weed killers on your lawn.

Do You Need to Remove Weeds Before Overseeding?

Overseeding is most effective when you kill existing weeds before you overseed. This is because grass can’t choke out existing, established weeds no matter how thick it is. A lush lawn can only stop new weed seeds from sprouting. Also, any weeds that are present when you overseed will steal water, nutrients, and sunshine from your new grass seedlings. Wipe out the weeds to give your grass a fighting chance.

  • Remove existing weeds before you overseed.
  • Existing weeds won’t be killed or choked out by overseeding. A thick, overseeded lawn will only suppress new weed growth.
  • Kill established weeds or they will rob water and nutrients from your grass seedlings.

You’ll get more new grass sprouts from overseeding if you kill existing weeds first. Overseeding a lawn overgrown with weeds will get a poor yield. Your new grass will struggle to compete with the weeds. Paving the way for new grass by killing weeds is your best bet.

What is the Best Time of Year to Overseed a Weedy Lawn?

For the best results overseeding your lawn, you need to seed at the optimal time for your grass type. Warm-season grass lawns (such as Bermuda, Zoysia, and Centipede grass) should be overseeded in spring. Cool-season grasses (Kentucky Bluegrass, Fescue, Ryegrass) sprout and survive best when overseeded in fall.

  • Overseed warm-season grasses in spring.
  • Overseed cool-season grasses in fall.
  • It’s best to overseed when no weeds are present.

Another factor that makes overseeding in fall a great option for cool-season grass lawns is that few weeds will be present. Even if your lawn was infested with crabgrass in spring, by fall it will have begun to drop its seeds and die off. If you overseed in fall, your new grass will sprout and establish itself. By spring, the grass will be thick enough to prevent many of those crabgrass seeds from sprouting.

What is the Best Grass Seed to Use for Overseeding?

The best grass seed for overseeding is grass that will grow well in your climate. In regions with freezing winters, choose cool-season grass. In regions where winters seldom freeze, warm-season grass will perform best.

  • Seed with cool-season grass in regions with freezing winters.
  • In regions with mild winters, overseed with warm-season grass.
  • Match your grass seed to the variety of grass present in your lawn.

It’s also important to note that overseeding is the act of spreading additional grass seed over an existing lawn. It’s usually best to overseed your lawn with the same species of grass that is present there. This will create a uniform, beautiful lawn.

What Grass Will Choke Out Weeds?

The best grasses for choking out weeds in your lawn depend on your location. If you are planting warm season grass and wish to have a weed-resistant lawn, Bermuda grass is your best choice. It spreads through runners and roots to take over areas, which prevents weeds from getting a toehold.

  • Bermuda grass is the best warm-season grass for choking out weeds.
  • Kentucky Bluegrass is the top option for battling weeds in cool-season grass lawns.

Kentucky Bluegrass spreads faster than any other cool-season grass. It produces roots that form new plants in both spring and fall, meaning it self-thickens and fills in bare spots. If you want to weedproof your northern lawn, go with KBG.

Will Overseeding Your Lawn Get Rid of Weeds?

Overseeding a weedy lawn will not kill weeds on its own. However, thick grass growth produced by overseeding prevents new weeds from sprouting. In order to keep your lawn weed-free with overseeding, first, kill any existing weeds, then prep your lawn and spread new grass seed. The thick growth of new grass will choke out new weed seedlings as they attempt to sprout.

How to Pick Out The Best Grass Seed

Bare spots in your lawn got you down? Are you creating a new lawn? Either way, you’ll need some advice on the best grass seed! The best grass seed for cool season grasses used in Ohio lawns are Kentucky bluegrass and tall fescue grass. Cool season grasses grow best between 65 to 75 degrees Fahrenheit, making the spring a good time to start taking care of all of those brown spots on your lawn. Both are great grasses, but there are a few differences in them that one person or homeowner may prefer over the other. Read up on Kentucky Bluegrass and Tall Fescue to see if they seem like they are the best grass seed for your lawn.

Kentucky Bluegrass

Kentucky Bluegrass is one of the best grass seeds. It is a cool season grass popularly used in Ohio. Fun Fact – this grass originated from Europe and Northern Asia! Kentucky Bluegrass grows vigorously when it is cooler outside in the spring and fall. In the summer heat, the grass grows very slow. This cold seasonal grass has shallow roots, which makes the grass not very drought resistant because it cannot hold a lot of water. This makes the grass have a lower tolerance for heat as well. When Kentucky Bluegrass is healthy, it grows beautifully with an emerald green color that has a hint of blue in the lawn. If you have a lawn with Kentucky Bluegrass, it is important to make sure you water your lawn regularly to keep it green and healthy because it cannot store as much water in its roots as fescue or other cool season grasses. The seeds in the Kentucky Bluegrass spread quite well, making it easy to repair damage and grow a thick lush lawn.

Tall Fescue Grass

Tall Fescue grass is another one of the best grass seeds for cool season grass. It is abundant in the Ohio area. This grass is very resilient and it thrives in the spring, summer, and fall. It can withstand the harsh cold of the winter which sounds perfect for our crazy Ohio seasonal weather. The root system grows deep into the ground, 2 to 3 feet, making it drought resistant and able to endure the high heat of the late summer, unlike the Kentucky Bluegrass. Tall Fescue grass absorbs much more water than most other cool season grasses because of its deep roots. In fact, your lawn may require 30 percent less water per year to stay hydrated and healthy than other grasses.

Buying The Seed

When you have decided on the best grass seed and go to purchase the bags for your lawn, there are a few things you should know. With whatever grass seed you decide to buy, pick out a 75/25 mixture with 25 percent annual rye. The annual rye will not grow back after the first year, but it will cause the perennial grass to sprout and grow strong from the seed. The rye germinates faster than the other seeds, making the rye able to protect and shade the growing grass. The harsh rain storms can wash away the seeds if there is not annual rye to protect it. Imagine doing all of the hard work of seeding for nothing!

Take Care of Your New Grass

There are some treatments that will help your new grass thrive. Be sure to do some of the following treatments on your lawn.

Aerate

Lawn aeration relieves compaction in your lawn and allows room for roots to spread and grow in the soil. Core aeration removes small plugs of soil from your lawn. When the holes are in the ground from aeration, it is the perfect time to seed. The seeds with be able to make contact with the soil much easier when the lawn is punctured and cored. If you are seeding your lawn because of bare spots, know that bare spots are a symptom of a compacted lawn so aeration will be beneficial to keep it healthy and avoid future bare spots. Some other symptoms of a compacted lawn are puddles and pooling in the yard and dry brownish lawns. You should aerate your lawn at least once a year to help make your lawn greener and healthier.

Fertilize

Fertilizer provides your lawn with vital nutrients that may not be provided through your soil naturally. In order to most effectively add nutrients to your lawn, you or your lawn fertilizing company should take a sample of your soil and test it to see which nutrients occur naturally in the soil. Using this information, the lawn company should be able to give your lawn the lacking nutrients. Early spring fertilizing is something we want to do with our cool season grasses. It is best to get a few fertilizing treatments in before it gets too hot outside because fertilizer does not work well with high heat. A really great time to fertilize is right after your lawn has been aerated. The cored soil will be able to absorb the nutrients very well.

Mowing Your Lawn

Did you know you might be cutting your lawn too short? The recommended height for Kentucky Bluegrass and Tall Fescue is around two to three inches. You can mow your lawn after the new seeds have reached mowing heights , but this can take up to 4 weeks or more. Generally, you would think cutting the grass shorter would be better, but having a longer lawn is actually better for the health of your grass. Having longer grass will allow for more water retention and the longer blades of grass will create more shade for the roots of the grass. Keeping a longer lawn will inevitably lead to your lawn needing to be mowed more often, but the health and beauty of a greener lawn is worth it. Lawn mowing can begin in the spring as soon as you notice growth in your lawn. When scheduling your spring lawn care services, ask to see if they can keep your lawn a little bit longer to keep your lawn healthier.

Best Grass To Choke Out Weeds

Many homeowners fantasize about having a lush, green grass carpet for their children and pets to play on.

However, accomplishing this can be challenging because of difficult growing conditions. A yard can swiftly be ruined by disease, dryness, and, most of all, weeds. Growing grass that chokes out weeds can make all the difference come the summer months.

You can find many grass seed types, yet you need to make sure you are overseeding lawn with weeds with the right grass seed.

In our guide, you can find the best grass seed you can use to grow a great lawn that can choke out weeds. By the end, you’ll have options from cool-season grasses, warm-season grasses, or a mix to offer a green lawn for longer and a hardy grass that can deal with weeds on your behalf.

Will Healthy Grass Choke Out Weeds?

Regardless of the type of grass, weeds need certain growing conditions. Thus, you need to ensure you have healthy grass growing to fend off weeds.

Here are a few ways suitable for various grasses to help them thrive.

Mowing Habits

Mowing height has a significant impact on your lawn’s health. Too short grass permits weed seeds to get sunlight, whereas taller grass blocks it. Mow your lawn in thirds; longer grass is better than shorter grass.

Mow and let the clippings fall. Grasscycling can help wipe out weed seeds while supplying nutrients to your lawn. You get less work, and your yard benefits! Grasscycling just after a rain might cause lawn illness due to damp grass blades.

Water Deeply

The only thing grass needs besides fertilizer are water. Irrigation encourages deeper roots and healthier grass, where your grass overpowers weeds and denies them nutrition. Proper watering will choke out existing weeds and inhibit new weed growth. See our lawn watering guidelines for assistance on properly hydrating your grass. (Learn How Often Should You Water Your Vegetable Garden)

Aerate Your Lawn

Weeds grow in compacted soil, which is why you see weeds in unmaintained parks and ballfields. Aeration loosens soil, allowing oxygen, water, and nutrients to reach grass roots. Weeds hate healthy soil and healthy grass. Consult a local lawn care expert for further information on aeration and available aerators.

Can You Plant Grass Seed On Top Of Weeds?

A weedy lawn can be replanted with grass seed. However, dealing with the weeds first will yield better results if the weeds are thick. Pull the most significant weeds first, then apply the grass seed if only a few weeds.

Warm-season and cool-season grasses are the two main types of grass seed. Warm-season grasses are substantially more tolerant of hot southern climes than cool-season grasses.

Warm-season grasses brown as they go dormant in the winter. Cool-season grasses proliferate in the cooler months of the year, then go dormant in the summer heat. Warm-season grasses can be reseeded in the spring and summer, whereas cool-season grasses should be reseeded in the spring and fall to get the most beautiful lawn. (Read Tall Fescue Vs Kentucky Bluegrass)

Warm Season Grasses

Bahia: This warm-season grass is preferred in hot areas with long dog days because of its heat tolerance and drought resistance. With large leaves and gritty texture, Bahia grass survives in the intense sunny areas where other grasses perish. In the Deep South, this makes it a desirable low-maintenance grass species all summer long.

Bermuda: Like many other warm-season grass types, Bermuda grass flourishes in hot regions because of its excellent ability to survive the heat and high foot traffic. Bermuda grass demands plenty of nutrients, proper drainage, and full sun exposure. Because the grass can not take cold climates well, it is best used in the southern part of the country with hot climates.

Buffalo: Despite being classified as warm-season grass, Buffalo grass thrives in a wide range of climates and is popular in places with harsh winters. In colder weather, it goes dormant and turns brown, just as other warm-season grasses. The months of April and May are ideal for planting buffalo grass.

Centipede: Centipede grass is noted for high heat tolerance and low maintenance needs. This makes it a popular lawn grass for folks who don’t want to spend much time on their lawns. Centipedes prefer full sun, but they can also take partial shade. It thrives in the Southeast because of those requirements. When all threat of frost has gone, sow centipede grass seed in the spring.

St. Augustine: St. Augustine is one of Florida’s most popular grasses because of its ability to withstand extreme temperatures and humidity. It has blue-green grass blades that quickly grow across a yard. St. Augustine can also withstand saltwater, making it a popular choice for coastal areas. Planting plugs is one of the most successful ways to establish St. Augustine grass since it spreads quickly when sown in the spring or summer.

Zoysia: Zoysia lawn is tough, low-maintenance grass and is well-known for resistance to heat, drought, and heavy foot traffic. Zoysia lawns create dense grass that chokes out weeds while requiring little upkeep. Although some zoysia grass varieties are only grown from Zoysia sod or Zoysia plugs, several grass seed businesses offer a Zoysia seed variety. Once the fear of frost has passed, you should seed Zoysia grass in the spring.

Cool Season Grasses

Fescue: Tall fescue grass is the most common grass in the United States. This is due to its ability to adapt to various climates, as it can withstand heat, cold, shade, and drought. This is attributed to a deep root system that can reach two to three feet deep. Tall fescue is simple to grow, although it can suffer from excessive traffic. Tall fescue should be planted and reseeded in the fall and spring.

Kentucky Bluegrass: Blue Grass is the type of grass most people envision when they think of the ideal lawn. Kentucky bluegrass is a favored plant because of its rich green color. This grass is tough to grow and requires a lot of attention and care. Because of its thin root system, which does not endure heat well, is better suited to northern lawns. In the spring and fall, Kentucky bluegrass can be planted and reseeded.

Perennial Ryegrass: Annual ryegrass, a transitory grass used for erosion control, should not be mistaken for perennial ryegrass. Year after year, perennial ryegrass returns. Ryegrass is ideal for new lawns because it germinates quickly. It thrives in cooler locations with mild summers, but it can even be found in the southern United States. In the fall, perennial ryegrass should be sown or reseeded.

Will overseeding choke out weeds?

Overseeding your current lawn with new grass seeds fills in bare patches and promotes stronger grass. A dense grass lawn with no bare spots shadows the soil beneath it, preventing weed seedlings from receiving sunlight and destroying them. Thick-growing grass extracts moisture and nutrients from the soil before weed seedlings can reach them. To get the best results, use a weed killer on lawn weeds, then overseed to build healthy grass that won’t let weeds come back.

  • Weeds are less likely to invade bare regions that have been overseeded with grass.
  • Overseeding thickens lawns, preventing weed seedlings from receiving sunlight and nutrition and suffocating them.
  • Without using herbicides, regular overseeding creates a thick, weed-resistant lawn.
  • Grass plants, like all other plants, deteriorate and die. You may restore your lawn with fresh grass plants by overseeding. This continuous replenishment ensures that your lawn remains thick enough to smother new weeds. This means you won’t have to use chemical weed killers on your existing grass as often.

Removing Weeds Before Overseeding

  • When you kill existing weeds before overseeding, you get the best results. This is because no amount of grass, no matter how thick, can choke out existing, established weeds. Only healthy grass can prevent new weed seeds from germinating.
  • Any weeds present when you overseed can rob your new grass seedlings of water, nutrients, and sunlight. To give your grass a fighting chance, get rid of the weeds.
  • Overseeding will not kill or choke out existing weeds. A thick, overseeded lawn will suppress new weed growth.
  • Kill established weeds before they deplete your grass seedlings of water and nutrients.
  • If you eradicate existing weeds before overseeding, you’ll receive a better germination rate and more new grass sprouts. Overseeding weed-infested grass will cause a low yield, as fresh grass has difficulty competing with the weeds in an existing lawn.

Best Time of Year to Overseed Entire Lawn?

Seeding your lawn at the right time for your grass type will give you the best results. Warm-season grass lawns (including Bermuda, Zoysia grass, and Centipede grass) should be overseeded in the spring. When cool-season grasses (Kentucky Bluegrass, Fescue, and Ryegrass) are overseeded in the fall, they sprout and survive the best.

  • Overseed warm-season grasses in spring.
  • Overseed cool-season grasses in fall.

Another advantage of overseeding in the fall for cool-season grass lawns is that there will be fewer weeds. Even if your lawn were afflicted with crabgrass, it would have dropped its seeds in the spring and died off by the fall.

New grass emerges and establishes itself if you overseed in the fall. The grass grows thick, and you will have a dense turf by spring to prevent many of the crabgrass seeds from germinating.

Best Grass Seed for Overseeding?

The best grass seed for overseeding is the grass that thrives in your environment. Choose cool-season grass in areas with cold weather and warm-season grass that is heat tolerant and will perform best with mild winters; the optimal time is vital for all grasses to thrive.

It’s also worth noting that overseeding is planting more grass seed on top of an existing lawn. It’s usually better to overseed your lawn with the same grass species that already exists. This will cause a nice, consistent new lawn suitable for bare feet. (Learn How Long Does Grass Seed Last)

The best grasses for choking off weeds in your lawn are different depending on where you live. Bermuda grass is ideal if you want a weed-resistant lawn when planting warm-season grass. It takes over regions by runners and roots, preventing weeds from gaining a foothold.

Kentucky Bluegrass is the best choice for weed control in cool-season grass lawns. However, since it only delivers a lush lawn in cooler environments and doesn’t deal with heavy traffic as much, you have another option of grass to choke out weeds.

  • Zoysia lawn thrives in scorching heat but can also withstand temperatures as low as 30 degrees below zero, so it’s suitable for both harsh and mild weather situations. Amazoy plugs thrive in light and heat and are not harmed by snow or low temperatures.
  • All summer, you can find your Zoysia grass choking out crabgrass and other weeds thanks to its deep roots.
  • Zoysia grass also has countless other benefits.
  • Fewer chemicals: You save money and risk by not using weedkillers and pesticides.
  • The Zoysia grass can cure itself and doesn’t need replacing.
  • Zoysia grass acts as a network of plants and can survive heavy traffic.
  • Slopes, play areas, and bare spots benefit Zoysia grass and require less mowing.

Soil Conditions

  • Zoysia plugs thrive on a wide range of clay soils. Amazoy zoysia grass has strong roots that penetrate and generate air passageways, allowing for proper root development despite the deep nature of clay soils.
  • Amazoy zoysia grass can thrive in rocky soil, but you’ll need to mix in a layer of topsoil before planting.
  • Most salty soils will support Amazoy zoysia grass.
  • Sandy soil
  • Although Amazoy zoysia grass thrives in various soil types, you may need to raise pH to recommended levels of 6 to 7. You can do this with granulated lime.
  • Only needs 1-pound of nitrogen fertilizer for every 1,000 square feet of Zoysia grass lawn.

Sunlight

Zosia thrives in direct sunlight and can suffer partial shade so long as it receives at least 2 to 3 hours of direct sunlight every day. Soil pH can change beneath a tree, so test areas in shady areas first before sowing Zoysia seed.

Choked out Weeds

Growing a good Zoysia grass lawn from seed has proven challenging in the past. In contrast, zoysia seed has gone a long way in the last few decades. It now germinates more effectively, resulting in a magnificent lawn, but it still needs to satisfy some specific requirements to be successful.

The depth at which the Zoysia seed should be placed, the amount of light it requires, and the frequency with which it should be watered are precise measurements. To succeed, following the seed planting instructions will be necessary.

Zoysia grass resembles Kentucky bluegrass in texture and appearance. Each plug is a little piece of Zoysia sod that can be as small as a one-inch square but never smaller.
