Does Zoysia Grass Turn Brown in Winter: A Complete Guide

Does Zoysia Grass Turn Brown in Winter?

Zoysia grass is a popular warm-season turfgrass known for its lush, green appearance and ability to withstand high temperatures and drought conditions. However, one question that often arises is whether Zoysia grass turns brown in winter. In this article, we will explore the behavior of Zoysia grass during the colder months, including why it may turn brown and what you can do to help maintain its color and health.

Understanding Zoysia Grass

Before we dive into the winter behavior of Zoysia grass, let’s first understand this resilient turfgrass a bit better. Zoysia grass is native to warm regions such as East Asia and is well-adapted to thriving in hot and humid climates. It is known for its dense and tightly woven growth pattern and its ability to recover from damage fairly quickly.

Winter Dormancy

During the winter months, many warm-season grasses, including Zoysia grass, undergo a period of dormancy. Winter dormancy is a natural response to the colder temperatures and reduced sunlight that characterize this season. As a result, the grass’s growth slows down, and its color changes from vibrant green to a brown or tan shade.

Reasons for Winter Browning

Several factors contribute to Zoysia grass turning brown during winter dormancy:

1. Temperature: Zoysia grass thrives in warm temperatures and begins to slow down when the temperature drops below 55°F. Once the temperature consistently stays below this threshold, Zoysia grass starts entering dormancy and gradually turns brown.

2. Daylight: The shorter daylight hours in winter also impact the color of Zoysia grass. With reduced sunlight, the grass receives less energy for photosynthesis, leading to a change in its pigmentation.

3. Winter Stress: Cold temperatures, frost, and icy conditions can place stress on Zoysia grass, making it more vulnerable to browning. Factors like foot traffic, compacted soil, and inadequate moisture levels can exacerbate winter stress and increase the likelihood of browning.

The Benefits of Winter Dormancy

While it may be disheartening to see your Zoysia grass turn brown during winter, it’s important to remember that this period of dormancy is a normal part of its growth cycle. Winter dormancy actually offers several benefits:

1. Cold Hardiness: Zoysia grass is more cold-tolerant than many other warm-season grasses. Its dormancy allows it to conserve energy and survive the harsh winter conditions. Once the temperatures rise and sunlight increases, the grass will begin to recover and regrow.

2. Weed Suppression: During winter dormancy, Zoysia grass maintains some density, which helps suppress the growth of winter weeds. This can be advantageous when it comes to weed control in your lawn.

Promoting Winter Color Retention

While browning is a natural process during winter dormancy, you can take certain steps to promote better color retention and overall turf health:

1. Proper Mowing: Before winter sets in, mow your Zoysia grass slightly shorter than usual. Trimming the grass to a height of around 1.5 inches helps prevent snow mold and allows more sunlight to reach the crown of the grass, aiding in color retention.

2. Fertilization: Apply a slow-release, winterizer-type fertilizer before winter dormancy begins. This helps provide the necessary nutrients for the grass to store during dormancy, promoting quicker green-up once spring arrives.

3. Adequate Watering: While watering needs may be reduced during winter, it is important to ensure your Zoysia grass receives adequate moisture. Water deeply but infrequently, allowing the soil to dry out slightly between watering sessions. Be cautious not to overwater, as it may lead to disease issues.

4. Reducing Winter Stress: Minimize foot traffic on your lawn during winter and avoid parking heavy vehicles on it. This reduces compaction and stress on the grass. Additionally, avoid applying excessive herbicides during this period, as Zoysia grass may be more susceptible to damage.

Spring Transition and Green-Up

As winter gives way to spring, and the temperatures begin to rise, Zoysia grass gradually emerges from its dormant state. With increased sunlight and warmth, the grass starts the process of greening up and regrowing. It’s important to note that the exact timing of green-up can vary depending on the specific Zoysia grass cultivar, location, and climate conditions.

In Conclusion

Zoysia grass, like many other warm-season turfgrasses, turns brown during winter dormancy. While this may initially be a cause for concern, it is a natural and necessary part of its growth cycle. By understanding the reasons behind winter browning and following some key maintenance practices, you can ensure that your Zoysia grass remains healthy and vibrant when spring arrives. Embrace the beauty of this hardy grass and look forward to its green return each year.
