Caring for a dormant warm-season lawn involves specific practices to ensure it remains healthy and ready to thrive when the growing season returns. By understanding the particular needs of your lawn during dormancy, you can maintain its vigor and prepare for lush growth come spring.
What Is a Dormant Warm-Season Lawn?
Warm-season grasses, such as Bermuda, Zoysia, and St. Augustine, naturally enter a dormant state during cooler months. During dormancy, these grasses turn brown and stop growing, conserving energy until warmer temperatures return. Proper care during this period is essential to prevent damage and ensure a quick recovery.
How to Water a Dormant Warm-Season Lawn?
Even though your warm-season lawn is dormant, it still requires some moisture to survive. While the grass doesn’t need as much water as in the growing season, maintaining adequate soil moisture is crucial.
- Check soil moisture: Use a screwdriver to test soil moisture. If it penetrates easily, the soil has adequate moisture.
- Water sparingly: Water only during prolonged dry spells, typically every two to three weeks, ensuring the soil is moist but not soggy.
- Avoid overwatering: Excessive water can lead to root rot and other fungal issues.
Should You Fertilize a Dormant Lawn?
Fertilizing a dormant lawn is generally not recommended. Applying fertilizer during dormancy can lead to nutrient runoff and doesn’t benefit the grass, as it’s not actively growing.
- Skip fertilization: Save fertilizing for the growing season when the grass can utilize the nutrients effectively.
- Plan for spring: Apply a balanced fertilizer in early spring as the grass begins to green up.
How to Mow a Dormant Lawn?
Mowing is typically unnecessary during dormancy since the grass is not growing. However, there are a few considerations to keep in mind:
- Final mow: Perform a final mow in late fall, lowering the height slightly to prevent matting.
- Avoid mowing dormant grass: Mowing during dormancy can damage the grass and impede spring recovery.
Should You Aerate or Dethatch a Dormant Lawn?
Aeration and dethatching are best performed during the active growing season, not during dormancy. These practices can stress the grass if done at the wrong time.
- Schedule for spring or fall: Plan aeration and dethatching for when the grass is actively growing and can recover quickly.
- Monitor thatch levels: Keep an eye on thatch buildup and address it in the appropriate season.
How to Protect a Dormant Lawn from Winter Damage?
Protecting your lawn from winter damage involves a few preventive measures to ensure it remains healthy through dormancy.
- Minimize foot traffic: Avoid walking on the lawn to prevent soil compaction and grass damage.
- Clear debris: Remove fallen leaves and debris to prevent mold and smothering.
- Monitor pests: Check for signs of pests and treat them promptly to prevent damage.

How Long Does Warm-Season Grass Stay Dormant?
Warm-season grasses typically stay dormant for about three to four months, depending on the climate. In regions with mild winters, dormancy may be shorter, while in areas with harsher conditions, it can last longer.
Can You Overseed a Dormant Warm-Season Lawn?
Overseeding a dormant warm-season lawn with cool-season grass, such as ryegrass, can provide a green lawn throughout winter. This practice, known as winter overseeding, is common in warmer regions to maintain aesthetic appeal.
What Is the Best Time to Apply Pre-Emergent Herbicides?
The best time to apply pre-emergent herbicides is in early spring before weeds germinate. Applying them during dormancy won’t be effective since weeds aren’t actively growing.
How Can You Tell If a Lawn Is Dormant or Dead?
A dormant lawn will be brown but will still have flexible and resilient blades. A dead lawn, however, will have brittle, dry grass that breaks easily. Performing a tug test can help determine the difference—dormant grass will remain rooted, while dead grass will pull out easily.
What Are the Signs of a Healthy Dormant Lawn?
Signs of a healthy dormant lawn include a uniform brown color, absence of significant thatch buildup, and no signs of pest or disease damage. Proper care during dormancy will prepare the lawn for a robust return in spring.
Summary
Caring for a dormant warm-season lawn requires understanding its unique needs during the cooler months. By providing minimal yet essential care, such as occasional watering and protection from winter damage, you can ensure your lawn remains healthy and ready to thrive when the growing season returns.
