Quick Answer: Zoysia grass spreads through aboveground stolons and belowground rhizomes, allowing it to establish new growth and cover large areas over time.
Introduction:
Have you ever wondered how zoysia grass manages to spread and create a lush green carpet wherever it grows? Well, the secret lies in its unique spreading mechanism. Zoysia grass, scientifically known as Zoysia spp., is a warm-season turfgrass that can quickly colonize an area through its aboveground stolons and belowground rhizomes. This remarkable ability to spread allows zoysia grass to cover bare patches and fill in gaps, creating a dense and uniform appearance.
Aboveground stolons, commonly referred to as “runners,” are horizontal stems that grow above the soil surface. These stolons extend outwards from the mother plant, sending down roots at regular intervals to establish new growth. This enables the grass to spread horizontally, gradually covering larger areas.
Belowground rhizomes, on the other hand, are underground stems that grow horizontally just below the soil surface. These rhizomes produce new shoots and roots, which emerge from the soil to form fresh stands of zoysia grass.
Together, the aboveground stolons and belowground rhizomes work harmoniously to enable zoysia grass to spread and establish new growth, making it an excellent choice for those looking to create a beautiful and expansive lawn.
How Does Zoysia Grass Spread?
Zoysia grass is a warm-season turfgrass that is known for its ability to spread and create a thick, lush lawn. Understanding how zoysia grass spreads can help you effectively maintain and care for your lawn. In this article, we will explore the various methods through which zoysia grass spreads, including stolons and rhizomes, as well as provide tips for promoting and controlling its spread.
Stolons: Above-Ground Spread
One of the primary ways zoysia grass spreads is through stolons. Stolons are above-ground stems that originate from the main plant and extend horizontally. They are also commonly referred to as runners. These runners grow along the soil surface, rooting at each node and eventually forming new plants. Here are some key points to know about zoysia grass stolons:
- Zoysia grass stolons grow rapidly during the warm summer months.
- They help the grass expand horizontally and fill in bare spots.
- Stolons can tolerate various environmental conditions, making zoysia grass adaptable and resilient.
- If not properly managed, zoysia grass stolons can invade flower beds, walkways, and other areas where you may not want it to grow.
Rhizomes: Below-Ground Spread
In addition to stolons, zoysia grass also spreads through rhizomes, which are below-ground stems that grow horizontally beneath the soil surface. Rhizomes are responsible for most of the vertical growth of zoysia grass. Here’s what you need to know about zoysia grass rhizomes:
- Rhizomes grow underground and can extend several inches beneath the soil surface.
- They enable zoysia grass to recover from damage and expand in various soil conditions.
- Rhizomes also help the grass withstand drought and other challenging conditions.
- If left unchecked, zoysia grass rhizomes can invade nearby areas and overtake other types of grass.
Promoting Zoysia Grass Spread
If you want to encourage zoysia grass to spread and create a denser lawn, there are several measures you can take:
- Periodically mow your lawn at a low height to stimulate stolon growth.
- Aerate the soil to reduce compaction and promote rhizome expansion.
- Apply a balanced fertilizer to provide essential nutrients for vigorous growth and spread.
- Water deeply and infrequently to encourage deep root growth and overall grass health.
- Overseed thin areas with zoysia grass seeds or plugs to speed up the spreading process.
Controlling Zoysia Grass Spread
While zoysia grass’s spreading ability is desirable for a thick, healthy lawn, it can become invasive and encroach upon unwanted areas. To prevent zoysia grass from spreading beyond its boundaries, consider the following measures:
- Install physical barriers like edging or garden borders to restrict the spread of stolons and rhizomes.
- Regularly inspect your lawn and remove any zoysia grass runners that have crossed into neighboring beds or walkways.
- Apply a selective herbicide specifically designed to control zoysia grass without harming surrounding vegetation.
- Maintain proper lawn care practices such as regular mowing and edging to minimize the potential for zoysia grass to escape its designated areas.
In conclusion, understanding how zoysia grass spreads through stolons and rhizomes is crucial for maintaining a healthy, well-manicured lawn. By promoting or controlling its spread, you can achieve the desired level of coverage while keeping it in check. Using the tips and strategies outlined in this article, you can unleash the full potential of zoysia grass and enjoy a beautiful, lush lawn for years to come.

Frequently Asked Questions
How does zoysia grass spread?
Zoysia grass spreads in several ways, primarily through stolons, rhizomes, and seeds.
What are stolons and how do they contribute to the spread of zoysia grass?
Stolons are above-ground runners produced by zoysia grass. These horizontal stems grow across the soil surface, rooting at various intervals to form new plants. Stolons help zoysia grass spread laterally, creating a dense and interconnected turf.
What role do rhizomes play in the expansion of zoysia grass?
Rhizomes are below-ground stems that grow horizontally beneath the soil surface. Zoysia grass rhizomes enable the plant to spread and establish new shoots at different points along their length. This characteristic allows zoysia grass to fill in bare areas and expand its coverage.
Can zoysia grass spread by seeds?
Yes, zoysia grass can produce seeds, although it is a less common method of spread compared to stolons and rhizomes. The seeds are small and enclosed within spike-like structures, which develop during flowering. These seeds can germinate and establish new zoysia grass plants under suitable conditions.
What factors contribute to the spread rate of zoysia grass?
The spread rate of zoysia grass can vary depending on various factors. These include the specific zoysia grass variety, environmental conditions, soil fertility, and maintenance practices. Generally, zoysia grass tends to spread more rapidly in warm climates with proper irrigation and regular fertilization.
Is zoysia grass invasive due to its spreading ability?
Zoysia grass can be considered invasive in certain situations. While its spreading ability helps in forming a dense and robust turf, it can also encroach upon neighboring lawns, flower beds, or other desired vegetation. Therefore, proper containment measures like edging or regular mowing along borders are recommended to control its spread.
Final Thoughts
Zoysia grass spreads through both aboveground and belowground mechanisms. Aboveground, it spreads through stolons and rhizomes, which are above and below-ground shoots, respectively. These shoots grow outward, allowing the grass to spread horizontally. Belowground, zoysia grass forms a dense network of roots that can grow deep and wide. These roots help the grass establish itself in new areas and enable it to withstand drought and other harsh conditions. Overall, the ability of zoysia grass to spread rapidly is a key factor in its success as a turfgrass.
