Common Winter Lawn Diseases: Protecting Your Lawn from the Cold

As winter approaches in Oklahoma, it is crucial to be aware of the common lawn diseases that can wreak havoc on your turf. While the term "winter disease" may be misleading, as these diseases tend to emerge during fall and spring, they still pose a significant threat to the health of your lawn. In order to prevent the onset of grass diseases, it is essential to practice proper lawn care in winter, including the control of winter weeds and the utilization of lawn disease prevention techniques. Let's explore some of the most prevalent winter lawn diseases in Oklahoma and how you can safeguard your turf.

Brown Patch

This fungal disease is particularly common during the cooler months of the year. It presents as circular patches of brown, dying grass. To prevent Brown Patch, ensure adequate airflow and drainage in your lawn, avoid overwatering, and mow the grass at the correct height.

Dollar Spot

Another fungal disease that thrives in cool and humid conditions, Dollar Spot manifests as small, silver-dollar-sized patches of dead grass. To combat this disease, regular watering and proper fertilization are key, as well as ensuring that your lawn receives sufficient sunlight.

Spring Dead Spot

This is the most prevalent disease in Oklahoma, especially in Bermuda lawns. It appears as large, dead patches that fail to green up in the spring. To prevent Spring Dead Spot, overseed your lawn with disease-resistant grass varieties, avoid excessive thatch buildup, and maintain proper soil pH levels.

Large Patch or Brown Spot Disease

This fungal disease primarily affects warm-season grasses, causing large, irregular patches of dead grass. Implementing proper lawn care practices, such as regular aeration and dethatching, can help prevent this disease.

Winter Lawn Care Tips

To protect your lawn from these winter diseases, it is important to take proactive measures. Here are some essential tips for winter lawn care:

• Choose grass varieties that are well-adapted to Oklahoma's temperature and moisture fluctuations.
• Keep your lawn well-fed and properly fertilized throughout the year.
• Regularly aerate your lawn to improve soil drainage and prevent disease buildup.
• Control and remove winter weeds that can harbor pests and diseases.
• Avoid overwatering your lawn, as excess moisture can promote disease development.
