Grass as Lawn Weed Control

Will Healthy Grass Choke Out Weeds?

No matter what type of grass you have, 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 not only choke out existing weeds but also 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 and allows 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. If the weeds are thick, however, dealing with the weeds first will yield better results. 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.

Bahia Warm Season Grasses

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: Buffalo grass, despite being classified as warm-season 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 very 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.

Fescue grass Cool Season Grasses

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 seed fills in bare patches and promotes stronger grass all over. 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.

Pulling Weeds on your lawn

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)

Depending on where you live, the best grasses for choking off weeds in your lawn are different. Bermuda grass is the ideal choice 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.

In cool-season grass lawns, Kentucky Bluegrass is the best choice for weed control. 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 long, you can find your Zoysia grass chokes 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 all benefit from 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 top soil 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, it will be necessary to follow the seed planting instructions properly.

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.
