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.

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.

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.

Why Zoysia?

Zoysia is a particularly hardy grass that grows well in a wide range of conditions and requires far less watering and mowing than most grasses. At the same time, this “tough” grass creates a thick, soft carpet that feels great in bare feet. Zoysia is ideal because it actually grows differently. It sends out runners or “stolons,” expanding sideways more than it grows tall.

This is why it is so dense and effective at choking out most summer weeds and replacing existing grass. With our superior blend of zoysia, Amazoy®, you can plant a network of plugs in a new or existing lawn and it will grow into a lush, even, weed-free lawn within several growing seasons.

The key reasons zoysia is so attractive for homeowners:

Cuts water bills

  • Zoysia’s vigorous root system is so deep and extensive the grass rarely, if ever, needs watering — zoysia can really cut your water bills.

Reduces mowing by two-thirds

  • The lateral growth of zoysia means it grows tall very slowly — most people mow zoysia once for every three times they need to mow other grasses!

Zoysia thrives in heat and cold

“We planted Amazoy plugs three years ago and we cannot believe how beautiful our new lawn is. Our grand son loves to play outside when he comes to visit” —M.D.

  • “The hotter it gets, the better it grows.” Zoysia loves blistering heat and yet it won’t winter kill either — it can survive to 30° below zero. It’s perfect for extreme conditions as well as mild climates.
  • Amazoy plugs will thrive in the heat and sunshine, but will not be damaged by snow or cold weather conditions. Amazoy can withstand temperatures of 120° to -30°Fahrenheit.

Chokes out crabgrass and weeds all summer long

  • Your established zoysia lawn grows so thick with deep roots that crabgrass and other summer weed seeds cannot germinate.

No more chemicals

  • Since zoysia naturally resists insects and diseases, you avoid the cost, time and risk of exposing your family and pets to weedkillers and pesticides.

Never needs replacement — even heals itself

  • It’s beautiful and tough. The way it naturally grows outward along the ground in all directions, zoysia grass acts like a network of plants that can withstand heavy use, and will fill in if damaged.

Zoysia is THE answer for slopes, play areas and bare spots

  • You can’t beat zoysia for hard to cover spots, worn areas or to end erosion on slopes. It even levels out ground irregularities.
You don’t pamper zoysia – You enjoy it!

Soil Conditions

Clay Soil

“I always thought my Great Grandmother had the most beautiful lawn. It was like walking on carpet” —N.O.

Amazoy zoysia plugs will grow in all kinds of clay soils. Although clay soils are dense, Amazoy zoysia grass has strong roots that penetrate and create air passages for good root development.

Rock-like Soil

Amazoy zoysia plugs will grow in rock-like or granite soil, but you will need to mix in a layer of top soil before planting.

Salty soil

Amazoy zoysia plugs will grow in most salty soils. Because zoysia grass is highly salt tolerant, it is recommended for areas near coastlines where salty soils are often found. Amazoy will grow well in areas near roads and driveways that are salted to melt winter ice and snow.

Sandy soil

Amazoy zoysia plugs grow especially well in sandy soil because there are many airspaces that allow zoysia’s roots to penetrate, providing quicker root development.

Soil pH

Although Amazoy zoysia grass grows well in many different types of soil, the ideal soil pH level is 6 to 7. pH levels can be altered by using granulated lime to raise the pH level or small quantities of sulfur to lower it. When using sulfur, it is important not to over-apply, as sulfur is an acidifying agent that can burn lawns. Insert a pH meter into your soil at several locations to determine pH levels. We offer an easy to use pH Meter.

Full Sun

Shady Conditions

Amazoy can be planted in part shade, as long as the area to be planted gets at least 2 to 3 hours of direct sunlight a day.

If you are planting your plugs under trees, make sure that the pH of the soil is between 6 and 7. Trees have a tendency to alter the pH of your soil. pH levels can be modified by using granulated lime to raise pH and small quantities of sulfur to reduce it.

To determine the pH of your soil, use a pH meter or soil testing kit. We offer an easy to use pH Meter and Soil Test Kit.

Slopes and Borders

Excellent on Slopes and Hills

Amazoy zoysia works very well in areas with steep slopes and hills. Amazoy plugs make it easy to plant the grass on steep areas and once established they will create a thick carpet-like grass. It will also require less mowing, which can be difficult and dangerous on steep slopes.

Great Erosion Control

Amazoy’s deep root system (about 2 feet when fully established) and the thickness of the turf will work to significantly reduce slope erosion. Amazoy plugs make it easy to initially plant zoysia on steep areas as well.

Children and Pets

Safe for Children and Pets

Amazoy zoysia is completely safe for children and pets. Because there is no need to use poisonous chemicals on your lawn, your children and pets can romp on the lawn without fear of contamination. Zoysia’s durability means you will have no worries about damage that can result from lawn play.

More Tolerant of Animal Waste

Zoysia is more tolerant to pet urine and feces than most grasses. However, no grass will survive prolonged or constant exposure to pet waste. Pets should be kept off of the new plugs for at least 30 days in order for the plugs to become established.

After the plugs are established, you can minimize the effects of pet waste by periodically liming the soil in order to restore the pH level to an acceptable range between 6 and 7.

Safe for Horses and Dogs

Amazoy grass plugs are safe for horses and dogs. While zoysia has minimal nutritional value, eating zoysia will not harm horses and dogs.

“Many years ago my father plugged Amazoy zoysia grass into the family yard and it is still green as ever. It has absolutely choked out all the crab grass.” —P.D.S.

Safe for Wells and Septic Systems

Amazoy zoysia grass is safe for wells and septic systems as well as leach fields. The developed root system of zoysia may reach 2 or more feet below the soil surface but cannot penetrate well walls, septic systems or damage underground lines.

Resists Pests

Amazoy has an inherent resistance to the effects of most insects and diseases and resists injury from most chemicals when pest populations do require controls.

Chokes Out Weeds

Once established, the dense turf created by zoysia significantly reduces summer weeds. Amazoy will choke out all existing cultivated and wild grasses, including Bermuda (often called wire grass) and St. Augustine. For best results keep these grasses away from newly planted zoysia plugs.

Winter Dormancy

Zoysia, like deciduous trees, goes dormant after the first killing frost and will go off its green color until the ground reaches temperatures of about 50°F in the spring. This is a normal, healthy process. In fact, zoysia’s ability to go “dormant” is important to its ability to better withstand extreme winter cold and still come back full and green every spring. Amazoy will not be damaged by snow and cold weather conditions. Amazoy can withstand temperatures of -30°Fahrenheit ( -30°F below zero).

What About Zoysia Seed?

“We bought some plugs from you about a couple of years ago. We think there is nothing on the market that will touch them” —H.S.

Amazoy, the first Zoysia cultivar to be released by the US Department of Agriculture is still the superior standard. Vegetatively propagated Zoysia grass plugs provide the highest quality lawn.

Historically, it has been extremely difficult to create a fine Zoysia grass lawn from seed. However, Zoysia seed has come a long way over the last few decades. It now germinates better producing a beautiful lawn, but still has some very particular requirements in order to be successful. Our experience is that it is possible to establish a lawn from the Zoysia seed and we now are making available Zoysia seed to homeowners. We only supply what we believe to be the best of the best and the one that meets our standard for quality and durability.

There are very specific requirements for how deep to plant the seed, the amount of light it needs, and watering. It will be important to follow the seed planting instructions carefully for success.

“I am very proud of the way my plugs of (Amazoy) Meyer Z-52 grass have grown and spread and it is all that you have claimed for it” —A.B.

What do Zoysia Plugs look like?

Amazoy Zoysia grass resembles Kentucky bluegrass as far as texture and appearance. Each plug is a small piece of Zoysia sod that can measure as small as 1 inch square but can be much bigger in size just never smaller.

How are plugs shipped?

Amazoy Freestyle Plugs are shipped in 10″ by 15″ sheets of grass. Each sheet can produce up to 150 — 1″ square plugs. The plugs can be cut bigger, that’s the freestyle part. Bigger plugs means less cutting and less planting, but you will get less plugs from each sheet.

Super Plugs are precut for you into individual 3″ by 3″ plugs that are ready to plant. They will arrive in easy-to-handle trays of 15 Super plugs.

All plugs are shipped the same day they are packed with a moisture-proof lining so the roots reach you fresh, vigorous and ready to grow.

How long will the plugs last before planting?

Zoysia plugs are living plants, therefore, we recommend planting them as soon as possible. If the plugs cannot be planted upon receipt, remove them from the cartons, placing blade side up in an area that receives some sunlight (not direct sun). Mist the plugs with water and keep them moist until planting. Plugs must be planted within 2 weeks of receipt.

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.
