While zoysia grass is a popular choice for many lawns due to its durability and low-maintenance requirements, it may not always be the best fit for everyone. Whether you’re looking to replace zoysia grass with another grass type or want to start from scratch, getting rid of zoysia grass can be a challenging task. This article provides a comprehensive guide on how to get rid of zoysia grass, including various methods and techniques.
Zoysia grass originates from East Asia and has been a popular lawn grass option for decades. Its fine texture, dense growth pattern, and ability to tolerate both sun and shade make it an ideal choice for many homeowners. However, due to its aggressive growth and extensive root system, zoysia grass can be challenging to remove.
Most Successful Methods for Zoysia Grass Control
If you find yourself wanting to remove zoysia grass from your lawn, there are several methods you can use. We will explore some of the most effective ways to remove zoysia grass, including herbicides, tilling, solarization, smothering, and manual removal.
Herbicides are one of the most popular ways to remove zoysia grass. Selective herbicides that specifically target zoysia grass can be an effective way to remove it from your lawn. These products contain chemicals that kill the grass while leaving other plants unharmed.
There are several different herbicide products available on the market, including glyphosate, sethoxydim, and fluazifop. Glyphosate is a non-selective herbicide that can kill most plants, including zoysia grass. It works by interfering with the plant’s ability to produce proteins, causing it to die.
Sethoxydim and fluazifop are selective herbicides that target zoysia grass specifically. They work by inhibiting the grass’s ability to produce certain enzymes, which leads to its death. These herbicides are typically more effective than glyphosate when it comes to removing zoysia grass, but they can be more expensive and difficult to find.
Before using any herbicide product, it’s important to read the instructions carefully and follow them closely. Apply the herbicide on a calm day when there is no wind, and avoid applying it when rain is forecast within the next 24 hours. Wear protective clothing, including gloves, long sleeves, and pants, to avoid coming into contact with the herbicide.
Tilling the soil is another effective way to remove zoysia grass. This method involves digging up the grass and roots from the soil, which can be challenging with zoysia’s extensive root system. You can use a tiller, a shovel, or a hoe to loosen the soil and remove the grass.
Before tilling, it’s important to water the lawn thoroughly to make it easier to remove the grass. You should also remove any debris from the soil, including rocks and twigs, to avoid damaging your tools. After tilling, rake the soil to remove any remaining grass and roots.
Solarization involves covering the zoysia grass with clear plastic sheets to trap the sun’s heat, effectively killing the grass and roots. This method works best in warm, sunny climates and can take several weeks to be effective.
To use this method, first, mow the grass as short as possible, then water it thoroughly. Next, cover the grass with clear plastic sheets and secure them with stakes or rocks. Leave the plastic in place for at least six weeks, making sure to keep it tightly sealed to trap the heat.
Smothering involves covering the zoysia grass with mulch or heavy cardboard to deprive it of sunlight and nutrients, causing it to die off. This method is more effective when used in conjunction with other removal techniques.
To use this method, first, mow the grass as short as possible, then water it thoroughly. Next, cover the grass with a thick layer of mulch or heavy cardboard, making sure to overlap the edges to prevent any sunlight from getting through. Leave the cover in place for at least six weeks to allow the grass to die off.
Manual removal involves hand-pulling zoysia grass, which can be a time-consuming but effective way to remove it. However, it can be challenging to get all of the roots out of the soil, and it may not be practical for larger lawns. This method is best used for smaller areas or for spot-treating areas of the lawn where zoysia grass is growing.
To use this method, first, mow the grass as short as possible, then water it thoroughly. Next, use a garden fork or hand trowel to loosen the soil around the grass, making sure to get as much of the roots as possible. Pull the grass out by the roots, taking care to remove as much of it as possible.
After removing the zoysia grass, it’s important to prepare the soil for new grass seed or sod. This may involve adding topsoil, compost, or other soil amendments to improve the soil’s fertility and drainage.
Removing zoysia grass can be a challenging process, but with the right tools and techniques, it’s possible to achieve a beautiful, healthy lawn. Whether you choose to use herbicides, tilling, solarization, smothering, or manual removal, it’s important to take the time to prepare the soil for new grass seed or sod after the old grass has been removed. By following the steps outlined in this article, you can effectively remove zoysia grass from your lawn and create a beautiful, healthy outdoor space that you can enjoy for years to come.
Should I Put Sand On My Zoysia Grass?
No, you should not put sand on your Zoysia grass. Zoysia grass is a type of grass that is known for its ability to tolerate drought and heat. It does not need sand to thrive. Sand can actually be detrimental to Zoysia grass because it can compact the soil and reduce the amount of air and water that can reach the roots. Additionally, sand can cause the soil to become too dry, which can lead to the grass becoming stressed and more susceptible to disease.

Raking also helps to reduce thatch, which is a layer of dead grass and roots that can build up over time and prevent water and nutrients from reaching the grass. Additionally, raking can help to spread out fertilizer and other lawn treatments more evenly. Finally, raking can help to keep the grass looking neat and tidy.
What Selective Herbicide Kills Zoysia Grass?
Selective herbicides are designed to target specific types of plants, and there are several that are effective at killing zoysia grass. One of the most popular is called Dismiss, which is a post-emergent herbicide that targets broadleaf weeds and grasses. It is a selective herbicide, meaning it will only kill the targeted plants and not the surrounding vegetation. Dismiss is a systemic herbicide, meaning it is absorbed by the plant and moves throughout its system, killing it from the inside out. It is best applied in early spring or late fall when the zoysia grass is actively growing. It is important to follow the directions on the label to ensure proper application and to avoid damaging other plants in the area.
Will Zoysia Choke Out Other Grass?
Yes, Zoysia grass can choke out other grasses. It is a very aggressive grass that spreads quickly and can take over an area in a short amount of time.
