Controlling Zoysia Grass Growth: Effective Tips to Prevent Spreading

How to Stop Zoysia Grass from Spreading

Understanding Zoysia Grass

Before we delve into the methods to stop zoysia grass from spreading, let’s first understand what zoysia grass is and why it tends to spread aggressively. Zoysia grass is a warm-season grass species known for its ability to form dense and lush green lawns. It is highly popular due to its tolerance to heat, drought, and heavy foot traffic. However, one of the downsides of zoysia grass is its aggressive spreading nature. If left unchecked, it can quickly overtake other plants and invade surrounding areas.

The Factors Behind Zoysia Grass Spread

To effectively stop zoysia grass from spreading, it’s essential to understand the factors that contribute to its rapid growth and expansion. Here are some key reasons why this grass type can quickly take over your lawn:

1. Rhizomes: Zoysia grass spreads through underground stems called rhizomes. These rhizomes can grow horizontally, giving rise to new shoots and roots along their path. This allows the grass to expand rapidly and conquer new areas.

2. Stolons: In addition to rhizomes, zoysia grass also spreads through above-ground stems called stolons. Stolons enable the grass to creep along the surface, leading to the formation of new plants wherever they come in contact with the soil.

3. Drought Resistance: Zoysia grass possesses excellent tolerance to drought conditions. While other grass species struggle during dry periods, zoysia grass can survive and even thrive, allowing it to spread into areas where other grass types might perish.

4. Dense Growth: Zoysia grass forms a dense and compact turf due to its extensive root and stolon system. This tight growth pattern helps the grass compete against other plants, outcompeting them and taking over their space.

Effective Methods to Control Zoysia Grass Spread

Now that we understand the factors contributing to zoysia grass’s spread, let’s explore effective methods to control its expansion and prevent it from overtaking your lawn completely.

1. Edging and Barriers

Using physical barriers and edging can be an effective strategy to limit zoysia grass’s spread. Consider the following options:

  • Installing metal or plastic landscape edging: This creates a physical barrier that prevents zoysia grass from spreading into garden beds or other areas where you don’t want it.
  • Using deep edging: Digging a trench around your yard can help prevent the underground rhizomes from escaping and invading other areas.
  • Using root barriers: Placing root barriers made of thick plastic or metal underground can restrict the lateral growth of zoysia grass and prevent it from spreading into neighboring areas.

2. Regular Mowing and Trimming

Proper and regular mowing can help control the spread of zoysia grass. Follow these guidelines:

  • Set your mower blade at a higher height: Zoysia grass thrives when kept at a slightly taller length. Set your mower blade to a height of around 2 to 2.5 inches to discourage excessive spreading.
  • Mow regularly: Routine mowing helps prevent the grass from producing excessive stolons or rhizomes. Aim to mow your lawn at least once a week during the growing season.
  • Trim the edges: Pay special attention to the lawn edges, as zoysia grass tends to spread more aggressively in these areas. Use a string trimmer or an edger to keep the edges neat and prevent the grass from encroaching into unwanted spaces.

3. Proper Fertilization and Watering

While zoysia grass is known for its drought tolerance, providing optimal fertilization and watering can actually help slow down its spread. Here’s what you can do:

  • Avoid excessive nitrogen fertilization: Zoysia grass tends to spread more rapidly with excessive nitrogen. It’s recommended to follow a regular fertilization schedule but avoid over-fertilizing.
  • Water deeply but infrequently: Instead of frequent shallow watering, water your zoysia lawn deeply but less often. This promotes deeper root growth, making the grass less likely to spread aggressively.
  • Monitor soil moisture levels: Zoysia grass prefers well-drained soil. Avoid overwatering, as it may encourage rhizomes to spread more rapidly.

4. Hand Removal and Spot Treatments

For localized patches of zoysia grass that have already spread into unwanted areas, manual removal and spot treatments can be effective:

  • Hand pulling: For smaller infestations, carefully remove the zoysia grass by hand, making sure to extract as much of the rhizomes and stolons as possible.
  • Spot treatment with herbicides: Use selective herbicides specifically formulated to target zoysia grass without harming desirable turfgrass species. Apply them directly to the affected areas following the product instructions.

5. Overseeding with Competitive Grass Species

To discourage the spread of zoysia grass, consider overseeding your lawn with turfgrasses that are more competitive against zoysia. Some suitable options include:

  • Tall fescue: Tall fescue is a cool-season grass known for its ability to resist zoysia grass invasion.
  • Bermuda grass: Bermuda grass is highly aggressive and can outcompete zoysia grass in certain conditions.
  • Perennial ryegrass: Perennial ryegrass establishes quickly, creating a dense turf that helps prevent zoysia grass encroachment.

Wrapping Up

Controlling the spread of zoysia grass requires a combination of preventive measures and active management. By understanding its growth patterns and implementing the recommended strategies, you can effectively halt the aggressive spread of zoysia grass and maintain a well-balanced lawn. Remember to regularly monitor your lawn and take prompt action to prevent further encroachment. With these techniques in your arsenal, you can regain control over your yard and enjoy a beautiful, zoysia-free landscape.
