Thriving Zoysia Grass in Winter: Essential Tips

Zoysia Grass in Winter: A Comprehensive Guide


During the winter months, maintaining a lush and green lawn can be challenging. However, with proper care and attention, zoysia grass, a warm-season grass variety, can withstand the cold temperatures and remain healthy throughout the winter season. In this comprehensive guide, we will explore the best practices for caring for zoysia grass during winter, including important subtopics such as winterizing techniques, cold tolerance, and common winter issues.

Understanding Zoysia Grass in Winter

Zoysia grass (Zoysia spp.) is a warm-season grass variety that thrives in warm, humid climates. It is known for its dense and durable turf, making it a popular choice for lawns, golf courses, and athletic fields. While zoysia grass is well-adapted to warm temperatures, it can also survive and maintain its color during winter by going dormant.

Dormancy and Winter Color

During the winter months, zoysia grass enters a state of dormancy to protect itself from the harsh conditions. It slows down its growth, and its color may change from lush green to a golden or tan hue. This change in color is a natural response to the colder temperatures and reduced sunlight, and it does not indicate any health issues. It is important to understand that dormancy is a survival mechanism for zoysia grass, and it will regain its green color once the temperatures rise again in the spring.

Cold Tolerance

Zoysia grass exhibits varying degrees of cold tolerance depending on the specific cultivar. Some varieties, like Meyer Zoysia and Zeon Zoysia, are more cold-tolerant than others. These cultivars can withstand frost and freezing temperatures better than less cold-tolerant varieties. When choosing a zoysia grass variety for your lawn, consider your region’s climate and opt for the most suitable cultivar to ensure better winter survival.

Winter Care Tips for Zoysia Grass

To help your zoysia grass survive and remain healthy during the winter season, it is essential to implement proper winter care techniques. Here are some tips to ensure your zoysia grass is well-prepared for the coldest months of the year:

1. Mowing

Before winter arrives, gradually lower the mowing height of your zoysia grass to the lowest recommended height for your specific cultivar. This will help prevent snow mold and matting issues during the winter months. However, avoid scalping the lawn too aggressively, as it may stress the grass and leave it vulnerable to winter damage.

2. Fertilization

Applying a slow-release winter fertilizer in late fall is crucial for zoysia grass. This will provide essential nutrients to the grass roots, promoting stronger and healthier growth when spring arrives. Opt for a fertilizer with a higher potassium (K) content to enhance the grass’s cold tolerance and aid in its winter survival.

3. Aeration

Aerating the soil in late summer or early fall before winter sets in can greatly benefit zoysia grass. Core aeration helps alleviate soil compaction, improves drainage, and allows better airflow to the grass roots. These factors contribute to overall turf health and increase the chances of a successful winter dormancy period.

4. Weed Control

Winter is an ideal time to address any weed issues in your zoysia grass. Before the cold season arrives, apply a pre-emergent herbicide to prevent winter weeds like annual bluegrass and henbit from taking over your lawn. Be sure to follow the product instructions carefully and use a herbicide that is safe for zoysia grass.

5. Thatch Management

Thatch buildup can hamper zoysia grass’s ability to withstand winter stresses. To prevent excessive thatch, incorporate regular dethatching into your lawn maintenance routine. Dethatching removes the layer of dead grass stems and roots, allowing better air and water penetration into the soil.

6. Snow Removal

When it snows, avoid piling up snow on your zoysia grass for an extended period. Excess snow can smother the grass and create an environment conducive to snow mold development. Use a broom or a lightweight shovel to gently remove any accumulated snow and minimize potential damage to the grass.

7. Irrigation

During winter, zoysia grass requires less water due to its dormant state. Adjust your irrigation schedule accordingly and reduce the frequency and duration of watering sessions. However, it is essential to keep an eye on the moisture levels in the soil. If prolonged dry spells occur, provide your grass with deep watering to prevent dehydration.

Common Winter Issues for Zoysia Grass

Despite your best efforts, zoysia grass may still encounter some common issues during the winter months. It is crucial to be aware of these problems and take appropriate action to prevent or mitigate any potential damage. Here are a few common winter issues that zoysia grass may face:

1. Snow Mold

Snow mold is a common fungal disease that affects zoysia grass during extended periods of snow cover. It presents as circular patches of dead and matted grass, often covered with a white or pink fungal growth. To prevent snow mold, ensure proper airflow by avoiding excessive thatch and removing snow from the grass promptly.

2. Winter Weeds

Winter weeds can be particularly troublesome during the cooler months. Keep an eye out for invasive weeds like annual bluegrass, chickweed, and henbit. Apply pre-emergent herbicides in late fall to prevent these weeds from germinating and taking over your lawn.

3. Winter Desiccation

Winter desiccation occurs when zoysia grass loses too much moisture during the winter months. This is particularly common in regions with dry and windy winters. To prevent winter desiccation, ensure your grass is adequately hydrated before the onset of winter, and provide supplemental watering during dry spells.

While zoysia grass may appear dormant and change color during the winter, it is a resilient grass variety that can endure the cold temperatures and bounce back to life when spring arrives. By following the proper winter care practices outlined in this guide, you can ensure the health and longevity of your zoysia grass throughout the winter season. Remember to adjust your mowing, fertilization, and watering routines, and address any potential issues promptly to maintain a vibrant and thriving lawn all year round.

Question: Does zoysia grass need any special care in winter?
Answer: Zoysia grass requires minimal maintenance during the winter months. It is best to avoid fertilizing or mowing when the grass is dormant. However, it’s essential to keep the lawn free of debris, such as fallen leaves, to prevent potential disease or pest issues.

Question: Can zoysia grass survive cold winters with freezing temperatures?
Answer: Zoysia grass varieties exhibit varying tolerance to cold temperatures. Some varieties, like Meyer Zoysia and Amazoy Zoysia, are more cold-tolerant and can survive freezing winter temperatures. However, they may still go dormant and turn brown in extremely cold conditions.

Question: Should I water zoysia grass during winter?

Question: Can zoysia grass be overseeded in winter to maintain its green appearance?
Answer: Overseeding zoysia grass in winter is not recommended. Zoysia is a dense grass that tends to inhibit the growth of other grass varieties. Overseeding can lead to competition for resources and may result in the decline of the zoysia grass itself. It’s best to wait until spring to promote healthy growth and recovery.

Question: How can I prepare zoysia grass for winter?
Answer: To prepare zoysia grass for winter, it’s recommended to mow it slightly shorter than usual in the late fall. This helps minimize snow mold and allows for more effective winterization. Additionally, removing fallen leaves and keeping the lawn free of debris will prevent potential disease or pest issues during the dormant period.

Final Thoughts

In winter, Zoysia grass undergoes a period of dormancy, where it may turn brown or straw-like in appearance. However, this does not mean it is dead or damaged. Zoysia grass is incredibly resilient and has adapted to withstand harsh winter conditions. It is known for its ability to bounce back once spring arrives. While the winter color may not be as aesthetically pleasing, Zoysia grass still offers many benefits such as erosion control and weed suppression. So, don’t worry if your Zoysia grass appears dormant in winter – it’s just resting and will thrive again come springtime.
