How Does Zoysia Grass Spread?
Zoysia grass has two primary methods of spreading, stolons and rhizomes, which are both horizontal stems that grow above and below ground, respectively. Stolons are above-ground stems that grow along the surface, producing roots and new plants as they go. They’re responsible for the thick, carpet-like appearance of Zoysia grass. Rhizomes, on the other hand, are underground stems that grow horizontally and produce new shoots and roots.
Rhizomes allow Zoysia grass to spread in a dense and uniform manner, creating a tightly-knit network of plants. In addition to stolons and rhizomes, Zoysia grass can also spread through seeding and sodding. However, seeding can be unreliable and generally requires more maintenance, while sodding can be expensive. Environmental factors such as temperature, moisture, and soil type also play a role in how Zoysia grass spreads, as they can affect the growth rate and direction of stolons and rhizomes.
Stolons and Rhizomes
Stolons and rhizomes are the two main ways that Zoysia grass spreads horizontally. Stolons, also known as runners, are above-ground stems that grow horizontally along the soil surface. The nodes on the stolons produce roots and new shoots, which in turn produce their own stolons. This results in a network of runners that can quickly cover bare patches of soil and ultimately create a dense, lush lawn.
Rhizomes, on the other hand, are underground stems that grow horizontally in the soil. Like stolons, rhizomes produce roots and new shoots, which can lead to vegetative spread and the formation of a new plant. However, rhizomes are generally slower to spread than stolons and may require longer periods of time to establish themselves.
While both stolons and rhizomes are important for the spread of Zoysia grass, stolons are generally considered to be the more effective means of vegetative propagation. By utilizing stolons and rhizomes, Zoysia grass is able to spread quickly and aggressively, creating an attractive, low-maintenance lawn.
Seeding and Sodding
Seeding and sodding are two common methods for establishing Zoysia grass. Seeding involves spreading Zoysia grass seeds over a prepared area of soil, while sodding involves rolling out pre-grown Zoysia grass over the same area. Seeding Zoysia grass requires careful preparation of the soil, including removing any existing turfgrass, weeds, or debris, and leveling the ground.
After tilling the soil to loosen it and improve drainage, Zoysia grass seeds can be spread using a broadcast spreader or hand-held spreader. A light covering of soil, straw, or mulch can then be applied to help keep the seeds moist while they germinate. It’s important to keep the soil consistently moist during the germination process, which usually takes around two to three weeks.
Sodding, on the other hand, involves purchasing pre-grown Zoysia grass sod and laying it over a prepared area of soil. This method is often a faster way to achieve a full Zoysia grass lawn, but it can be more expensive than seeding. Before sodding, the soil should be tilled and leveled, just like it would be for seeding. A layer of topsoil or compost may also be added to help improve the soil’s nutrient content.
Zoysia grass sod should be laid in a staggered pattern, similar to how bricks are laid, for optimal coverage and stability. Whether you choose to seed or sod your Zoysia grass lawn, it’s important to remember that proper watering and maintenance are essential for successful establishment.
Newly seeded or sodded lawns should be watered regularly to keep the soil moist, and they should be mowed at the proper height to encourage healthy growth and development. With proper care, your Zoysia grass lawn can thrive for years to come.
Environmental Factors
Environmental factors play a significant role in how Zoysia grass spreads. Zoysia grass thrives in warm environments with full sun exposure, making it an ideal turfgrass species for southern states. It’s also moderately drought-tolerant, meaning it can survive long periods without water.
However, it’s important to note that Zoysia grass does require some level of water to stay healthy and green. If you live in an area with low rainfall levels, you may need to supplement your Zoysia grass with occasional watering to ensure its survival. Another factor that affects how well Zoysia grass spreads is soil quality. Zoysia grass prefers well-draining soils that are slightly acidic, with a pH between 6.0 and 6.5. If your soil is compacted, poorly drained, or too alkaline, your Zoysia grass may struggle to establish and spread.
Finally, Zoysia grass can be affected by pests and diseases, which can impact its growth and spreading capabilities. Common Zoysia grass pests include chinch bugs, white grubs, and billbugs, while common diseases include brown patches and dollar spots. To prevent these issues, it’s important to monitor your Zoysia grass regularly and take appropriate measures if you notice any signs of damage or distress.
While environmental factors can certainly impact how well Zoysia grass spreads, this turfgrass species remains a resilient and adaptable choice for warm-season lawns. With proper care and maintenance, you can ensure that your Zoysia grass stays healthy and lush for years to come.

How to Plant Zoysia Grass
Planting Zoysia grass requires careful preparation, as this grass species has specific requirements and preferences. To get started, it’s important to choose the right time of year for planting. Zoysia grass should be planted in late spring or early summer when the soil temperatures are warm enough for the grass to germinate and grow.
Before planting, it’s essential to prepare the soil by removing any rocks, debris, and weeds and by tilling the soil to a depth of at least 4-6 inches. Once the soil is prepared, you can choose to plant Zoysia grass through seeding or sodding. Seeding can be a more cost-effective option, but it can take longer for the grass to become established.
Sodding, on the other hand, can provide an instant lawn, but it can be more expensive. Regardless of which method you choose, it’s critical to water the newly planted Zoysia grass regularly and to follow best practices for lawn care and maintenance, such as fertilizing and mowing regularly, to ensure the grass thrives and spreads.
Preparation
Preparing the soil correctly before planting Zoysia grass is essential to ensure the grass’s proper growth and establishment. The first step is to test the soil to determine its pH level. Zoysia grass thrives in acidic soil with a pH level between 6.0 and 7.0. If the soil is too alkaline, add sulfur to decrease the pH level. Conversely, if the soil is too acidic, add lime to increase the pH level.
The second step is to remove any existing grass and weeds. This can be done with a sod cutter or by using herbicides. If using herbicides, make sure to read and follow the manufacturer’s instructions carefully. It’s best to wait at least two weeks after applying herbicides before planting Zoysia grass to ensure that all weeds are dead.
The third step is to till the soil to a depth of six inches to loosen compacted soil and remove any debris. Use a rake to remove rocks, roots, and other debris from the soil.
The fourth step is to level the soil to create a smooth and even surface. Use a garden rake or a lawn roller to level the soil. This will help prevent water from pooling in low areas and ensure that the Zoysia grass establishes uniformly.
Finally, the soil should be amended with organic matter. This can include compost, manure, or peat moss. The organic matter helps to improve soil structure, drainage, and nutrient retention, which will support the growth of healthy Zoysia grass.
Spread a layer of the organic matter over the soil and carefully rake it to a depth of about 2 inches. By following these steps, you can ensure that your soil is ready for planting Zoysia grass seeds or sod, and you’ll be on your way to a healthy and beautiful lawn or landscape.
Planting Methods
When it comes to planting Zoysia grass, there are two main methods: seeding and sodding. The method you choose will depend on your budget, the size of the area you’re planting, and the time you have available to devote to the project.
Seeding:Â Seeding is generally the more economical way to plant Zoysia grass. However, keep in mind that it can take longer to establish a full lawn using this method. Seeding is best done in the late spring or early summer when temperatures are warm, and the soil is moist. Before seeding, it’s essential to prepare the soil by removing all weeds, rocks, and debris.
You’ll also want to loosen the topsoil and add any necessary amendments, such as lime or fertilizer. After preparing the soil, evenly spread the Zoysia grass seed over the surface and gently rake it into the soil. Keep the soil moist until the seedlings emerge, which can take up to three weeks.
Sodding:Â Sodding is a more expensive but quicker way to establish a Zoysia grass lawn. With sodding, you’re essentially transplanting mature Zoysia grass plants, which can significantly reduce the time it takes for the lawn to become established. Sodding is best done in the late spring or early summer when temperatures are warm, and the soil is moist. Before sodding, prepare the soil by removing all weeds, rocks, and debris. You’ll also want to loosen the topsoil and add any necessary amendments, such as lime or fertilizer.
Next, lay the Zoysia grass sod in a brick-like pattern, making sure to stagger the joints so they don’t line up. Once the sod is installed, water it thoroughly to help it establish roots. Keep the soil moist, and avoid walking on the sod for at least three weeks to give it time to take root.
Care and Maintenance
To keep your Zoysia grass healthy and looking good, you’ll need to perform some routine care and maintenance tasks. Here are some tips to get you started:
- Watering:Â Zoysia grass is drought-tolerant, but it still needs regular watering to stay healthy. Water deeply and infrequently, rather than shallowly and frequently, to encourage deep root growth. Aim for about 1 inch of water per week, either from rainfall or irrigation.
- Fertilizing:Â Zoysia grass needs fertilizer to maintain its color and vigor, but too much fertilizer can lead to thatch buildup and other problems. Apply a slow-release fertilizer in the late spring or early summer, and then again in the fall. Follow the manufacturer’s instructions for application rates.
- Mowing: Zoysia grass generally needs to be mowed less frequently than other turfgrass species, as its slow growth rate means that it doesn’t produce as much top growth. Mow the lawn to a height of 1 to 2 inches, and never remove more than one-third of the grass blade at one time.
- Thatch removal: Zoysia grass can develop a layer of thatch – a layer of dead plant material that accumulates at the soil surface – over time. If the thatch layer becomes too thick, it can prevent water, air, and nutrients from getting to the roots of the grass. Use a dethatching rake or power dethatcher to remove thatch as needed.
- Weed control:Â Zoysia grass is relatively weed-resistant, but weeds can still crop up from time to time. Use an appropriate herbicide to control weeds, and always read and follow the label instructions carefully.
- Pest management:Â Some pests, such as chinch bugs, can cause damage to Zoysia grass. Use an appropriate insecticide to control pests, and consult with a lawn care specialist if you’re unsure what to use or how to apply it. By following these care and maintenance tips, you can help keep your Zoysia grass healthy and looking great all season long.
