How to Get Rid of Zoysia Grass

How to get rid of Zoysia grass

Zoysia grass grows during the warm season and spreads very quickly invading your lawn or garden. When the weather is dry, the leaves turn yellow or brown. If it has occupied a large territory, it will be a real headache to get rid of it completely.

Why You Can’t Remove Weeds Forever

Whichever method you choose, you will most likely have to reuse it, because the seeds of wild species are carried by the wind or birds. They can sprout even from a small piece of the root system, and it is difficult to pull them out completely. Herbicides are also not a guarantee that you will forget about weeds. Besides, many substances are harmful to crops and the environment.

Gardeners advise to properly trim the lawn – do it regularly and never leave bald spots. Timely and sufficient watering and trimming help lawn grasses to develop better. In favorable conditions, they will displace weeds.


At first, identify the plant to be sure that it is Zoysia grass. Use the pictures on the Internet to compare. If you deal with some other weed you can waste lots of time and money and have zero results.

In the south or moderately warm climate conditions, Zoysia grass is preferred due to many reasons. The first is drought tolerance. Also, it is not afraid of foot traffic. In cooler areas, it is very thick, but rich green leaves can turn yellow or beige, which spoils the whole look of the lawn. 

Zoysia grass hates sharp fluctuations of temperature. It survives in any stable climate conditions. That’s why it is not preferable for most home gardens. After you have checked the information, go on with the inspection phase. 

Inspect the area for the most invaded spots and identify the reasons why exactly these spots are invaded with the weed. Later it will be easier for you to apply herbicide treatment if needed. This creeping weed grows horizontally forming thick mats of grass and chokes all the plants in its way. 

13 Methods of Weed Control

Aggressive species interfere with the growth of vegetables, fruit, or crops. If they are not pulled out regularly, they will invade the entire space. Gardening work will become very labor-intensive. It is more convenient to work in the garden with the help of small shovels, hoes, or rakes. The main thing is to do this regularly at the beginning of summer before the seeds appear.

  1. Digging. It is best to dig up the area with a pitchfork – this way there is less chance that you will damage the roots and a new plant will sprout from them. In the process of digging collect all the roots, and then remove them away from the site.
  2. Mulching
    Cover the free space between the plants in your garden with a dense layer (2-4 inches) of mulch. It will block the sunlight from the seeds and they will not germinate.
  3. What will fit:
    • Pine bark, needles, and cones
    • Peat
    • Paper
    • Compost
    • Sawdust
    • Mown grass
    • Wood chips
    • Geotextile fabric or black film

    Compost, peat, humus may contain seeds of wild species. To check if there are any, pour mulch with water in the spring and cover with film. If green shoots appear after a few days, do not use the mixture. Leave it in a pile for a year. When decomposed, the temperature inside increases greatly, and all seeds die.

  4. Hand weeding. It is best to pull out the weeds after the rain – they are easier to remove from the moist soil with the root, and this slows down the appearance of new shoots. After you finish weeding, collect the debris and move it outside the area.
  5. Mechanical weeding. Here a variety of tools will suit. After you remove the root, a hole will remain on the surface of the lawn. It is better to sow it immediately, adding soil. So the lawn will become more attractive faster and there will be no room for a new wild one.
  6. Folk remedies.There are two powerful recipes with ingredients that can be found in every home or nearby store.
    Boiling water with a little soda will do. The solution slows down the growth of grass.Boiling water with salt and vinegar 9%. For one liter of water, you need 2 tablespoons of salt and 10 tablespoons of vinegar. In a day or two, everything that you have processed will die.
  7. Herbicides. Chemicals help to get rid of weeds and grass not forever, but for a long time. In an area near vegetables, fruit, and trees, herbicides must be used with caution. To achieve the result, three mandatory factors are needed: windless, clear weather, slightly wet leaves, and time. That means that three weeks before treatment, the weeds must not be watered with other means. Read the instructions carefully and follow all safety rules.While working with chemicals never forget about your protection. Take care of your skin with gloves and a long-sleeved shirt, and your eyes with goggles or any other special safety equipment. Be careful when you use a non-selective herbicide as it will kill all plants it comes in contact with. Be accurate in application not to spray it on the rest of the lawn.

    Step 1 Prepare the chemical and measure the territory

    To get rid of Zoysia grass you can use a non-selective, glyphosate herbicide with no soil activity. This chemical kills all the plants in contact so use it only for spot application. You can use some shield to protect your desired plants. As a shield, any plastic or cardboard box will do. You can apply a line with a dye to border the area which must be treated with a spray.

    Do the procedure in calm and not windy weather. When’s the territory invaded by Zoysia grass is impressive you will have to treat all the lawn and continue with reseeding and renovating the surface.

    Step 2 Treat Zoysia grass with herbicide

    Spray the spots of the weed generously to provide an even coating with the mixture. To get the best effect apply the herbicide when the grass is young at the beginning of summer. Over time when the weed is mature, it gets resistant to herbicide treatment and you will have to repeat the procedure several times.

    After several days the grass will start to fade, the blades will turn yellow and brown, and after approximately two weeks Zoysia grass will die. After processing for three to four days, a haircut is not carried out. If the desired result is not obtained, repeat the procedure but increase the dosage by half.

  8. Mixed vegetable garden. You can grow flowers and vegetables in the same garden. The main idea is not to let the soil be empty. The secondary culture will leave no room for weeds. Planting must be tight. The only point to consider is the compatibility of plants. Combine cucumbers with radishes and tomatoes, peppers with basil.
  9. Green manure. For the same purpose, green manure is sown. Colza, rape, mustard, phacelia, legumes enrich the soil with nitrogen and fill the free space. Don’t forget to cut green manure and dig the site in the autumn. Besides, it will be a great fertilizer
  10. Re-seeding. Another option is to re-sow fast-growing vegetables or herbs, for example, salad.
  11. Fire treatment. The surface is treated with a sliding flame of a blowtorch, without lingering in one place for a long time. After that, the ground is watered with cold water.
  12. A haircut. If you regularly cut the entire top of the weeds completely, then their number will be reduced. This is because the root system will use up nutrients to grow the stem again. This method will not work with all plants, but why not try it in combination with other methods?
  13. Black file or cloth. The main idea of this method is to prevent sunlight. Weeds like all other plants need sunlight to grow. You can use a black file, cloth, or any black roofing material. If it is not very heavy fix it with any boards or bricks on the surface of the soil. The only minus of this simple method is that you have to keep the territory covered all the season.
  14. Drip irrigation. If you water the cultivated plants directly to their roots weeds will suffer from the lack of moisture and die. Don’t splash water from a hose all over the site. Though it is very simple, it stimulates the growth of weeds.


Prevention is better than cure, especially in the case of stubborn Zoysia grass. Take certain preventative steps to be sure that it will not return. 

  • Trim and maintain the height of your lawn at about 3 inches. This way you will encourage intensive growth of the root system of the preferred species and prevent the reappearance of weeds. 
  • Don’t forget to add fertilizer at the most appropriate time for example in the fall.
  • Water is important to keep your lawn in a good condition. Deep and infrequent watering is the best – one inch of water once a week.
  • If you have a problem with poor drainage and you want to increase the aeration of your lawn, rake it regularly. 


What will kill zoysia?

There are a few different herbicides that will kill zoysia grass. We recommend using glyphosate-based products like Roundup or Raze. When applying herbicides to zoysia grass, follow the product’s instructions carefully and apply it when the plant is actively growing.

Some other popular herbicides that can be used to kill zoysia include Fusilade II and Finale. Again, be sure to follow the product label instructions carefully and apply the herbicide when the zoysia is actively growing.

It’s important to note that you may need to reapply the herbicide multiple times before the zoysia is completely eliminated. Be patient and consistent, and you will eventually see results.

Will Roundup for lawns kill zoysia grass?

There are a few different herbicides that will effectively kill zoysia grass, but Roundup for Lawns is not one of them. While Roundup may kill other types of weeds and grasses, it has no effect on zoysia. You’ll need to use a specific zoysia-killing herbicide to get rid of this weed.

Some common zoysia-killing herbicides include:

  • Imazapyr
  • Glyphosate
  • Quinclorac
  • Dicamba

When selecting an herbicide, be sure to read the label carefully. Some products may only be effective on certain types of zoysia grass.

How do you kill zoysia in bermuda grass?

The best way to kill zoysia in bermuda grass is to use a herbicide that contains glyphosate. Glyphosate will kill the zoysia plant without harming the bermuda grass. You can find glyphosate at your local garden center or nursery.

Another method to kill zoysia in bermuda grass is to physically remove the zoysia plants from the ground. This can be done with a spade or trowel. Be sure to remove as much of the root system as possible so that the plant does not regrow.

Once you have removed all of the zoysia plants, it is important to prevent new ones from growing. One way to do this is to apply a pre-emergent herbicide to the area. This will prevent new zoysia seeds from germinating. You can find pre-emergent herbicides at your local garden center or nursery.

By following these steps, you will be able to eliminate zoysia from your bermuda grass and keep it looking its best.

Will St Augustine take over zoysia?

The best thing you can do to get rid of zoysia is to plant st. Augustine in its place. Zoysia is a very difficult grass to eliminate. It has deep roots and an extensive root system that allow it to come back even after being treated with herbicides. The only sure way to get rid of it is by smothering it with another grass or groundcover. St. Augustine is the best choice because it’s a very aggressive grass that will quickly take over any area where it’s planted.

How do you stop zoysia from spreading?

The best way to stop zoysia from spreading is by using a herbicide that contains glyphosate. Glyphosate will kill the zoysia plant and prevent it from growing back. You can find glyphosate at most hardware stores or online.

Another way to stop zoysia from spreading is by physically removing the plant. This can be done by digging up the roots or pulling up the plant. However, this method is much more time-consuming and difficult than using a herbicide.

If you have zoysia on your property, it’s important to take action to prevent it from spreading. Zoysia is an invasive species that can quickly take over your yard and crowd out other plants. By taking steps to control it, you can help keep your yard healthy and beautiful.

How deep are zoysia roots?

The roots of zoysia grass are relatively shallow, growing to a depth of about six inches. However, the grass has a strong root system that can make it difficult to remove. If you’re trying to get rid of zoysia grass, you’ll need to be patient and persistent.

Here are a few tips to help you get rid of zoysia grass:

  • Use a sharp hoe or spade to dig up the roots. Be sure to dig deep enough to get all of the roots.
  • Apply an herbicide that contains glyphosate or imazapyr. These herbicides will kill the zoysia grass without harming other plants.
  • Cover the area with black plastic or a thick layer of mulch. This will smother the zoysia grass and prevent it from coming back.

How do you kill zoysia without chemicals?

The best way to kill zoysia without chemicals is by using a hand-held lawn edger or a spade. You need to remove the entire plant, including the roots. Be sure to wear gloves and long sleeves when removing Zoysia grass, as the plant can cause skin irritation.

If you have a small area of Zoysia grass, you can also try smothering it with black plastic. This method will take longer to kill the grass, but it is an effective way to get rid of it without using any chemicals.

Once you have removed all of the Zoysia grass from your property, be sure to reseed the area with a more desirable type of grass seed. This will help to prevent the Zoysia grass from coming back.

Will boiling water kill zoysia grass?

Boiling water will kill zoysia grass, but it is not a practical method for large areas. You would need to carefully pour boiling water directly onto the leaves of each plant, which is time-consuming and labor-intensive. If you have a small area of zoysia grass that you want to get rid of, boiling water may be a viable option.

Another option is to use an herbicide specifically designed to kill zoysia grass. There are many products on the market that will do the job quickly and effectively. Be sure to follow the instructions on the label carefully, as herbicides can be harmful if used improperly.

Will burning zoysia grass kill it?

The short answer is yes, burning zoysia grass will kill it. However, you need to be extremely careful when doing this because if not done correctly, you can easily start a wildfire. If you live in an area where wildfires are common, it’s probably best to avoid this method altogether.

There are two ways that you can burn zoysia grass: with a chemical herbicide or with a propane torch. We’ll go over both methods so that you can decide which one is best for your situation.

Using a chemical herbicide is the more popular method because it’s less likely to start a fire and it’s also more effective at killing the zoysia grass. You’ll need to purchase a herbicide that contains glyphosate and follow the instructions on the label.

Propane torches are less popular because they’re more dangerous and they’re not as effective as chemical herbicides. However, if you can’t find a glyphosate herbicide or you don’t want to use one for whatever reason, a propane torch is an option. Just be sure to exercise caution and follow all safety protocols.

In general, burning zoysia grass is an effective way to kill it but there are some risks involved. Be sure to weigh those risks before deciding whether or not this method is right for you.

Which is better, bermuda or zoysia?

It’s a common question, and there is no easy answer. Both grasses have their pros and cons. It really depends on your specific needs and preferences.

Bermuda grass is known for being tough and resilient. It can handle heavy traffic and withstands drought well. Bermuda is also a fast-growing grass, so it can quickly fill in any bare spots.

On the other hand, zoysia grass is slower-growing but thicker and more lush than bermuda. It’s also more tolerant of shade than bermuda, making it a good choice if you have areas of your yard that don’t get full sun. Zoysia generally requires less maintenance than bermuda, but it’s more expensive to install.

What are the pros and cons of zoysia grass?

Zoysia grass is a warm-season grass. Zoysia grass has a dense, thick growth habit and can smother out other types of grasses. It is also tolerant of shade and salt, making it ideal for coastal areas. Zoysia grass does have some drawbacks, however. It is a slow-growing grass, so it can take several years to establish a thick lawn. Additionally, zoysia grass goes dormant in the cold weather and turns brown. If you live in an area with freezing winters, zoysia may not be the best choice for your lawn.

How quickly does zoysia grass spread?

Zoysia grass can easily spread up to 12 inches in just one growing season. This means that if you have a small patch of zoysia grass, it won’t be long before it covers your entire lawn.

To make matters worse, zoysia grass is also very difficult to remove once it has taken root. This is because the roots of the plant are very strong and can quickly regrow if they are not completely removed.

If you want to get rid of zoysia grass for good, then you need to use a herbicide that contains glyphosate. Glyphosate is a chemical that kills plants by preventing them from making proteins.


Sometimes Zoysia grass is planted on purpose due to its unique look, but if it’s an unwelcome guest, it will be challenging to say goodbye. Of course, the listed methods will not solve the problem permanently, but some of them will greatly facilitate the life of gardeners.
