Caring for dormant grass involves understanding its needs during periods of inactivity, ensuring it remains healthy and ready to thrive when it becomes active again. By implementing a few key practices, you can maintain your lawn’s health even when it appears brown and lifeless.
What is Dormant Grass?
Dormant grass refers to grass that has temporarily stopped growing due to environmental conditions, such as extreme heat or cold. This natural survival mechanism helps grass conserve energy and water, allowing it to rebound when conditions improve. Dormancy is common in both warm-season and cool-season grasses, though it occurs at different times of the year.
How to Care for Dormant Grass?
Caring for dormant grass requires a strategic approach to watering, mowing, and fertilization. Here are some best practices:
-
Watering: Dormant grass requires less water than actively growing grass. However, it still needs occasional watering to prevent dehydration. Aim to water your lawn every 3-4 weeks during dormancy, applying about 0.5 inches of water each time. Adjust based on rainfall and soil moisture.
-
Mowing: Reduce mowing frequency when grass is dormant. If you do mow, set your mower blade higher than usual to avoid stressing the grass. Taller grass shades the soil, reducing evaporation and helping retain moisture.
-
Fertilization: Avoid fertilizing dormant grass, as it can stimulate growth that the grass cannot sustain. Fertilizing during dormancy can also lead to nutrient runoff. Wait until the grass shows signs of breaking dormancy before applying fertilizer.
-
Traffic Management: Minimize foot traffic on dormant grass to prevent damage. Dormant grass is more susceptible to wear and compaction, which can hinder its recovery.
-
Weed Control: Dormant grass is less competitive against weeds. Consider applying a pre-emergent herbicide before dormancy to prevent weed growth. Spot treat any weeds that appear to maintain lawn health.
Why is Watering Important for Dormant Grass?
Watering dormant grass might seem counterintuitive, but it is crucial for maintaining root health. While grass blades may not actively grow, roots continue to need moisture. Deep watering helps protect roots from drought stress, ensuring the grass can recover quickly when it becomes active again.
How Often Should You Water Dormant Grass?
- Frequency: Water dormant grass every 3-4 weeks.
- Amount: Apply 0.5 inches each watering session.
- Adjustments: Modify based on weather conditions and rainfall.
What Are the Signs of Dormant Grass?
Recognizing dormant grass helps differentiate it from dead grass. Here are common signs:
- Color: Dormant grass turns brown or tan but retains a firm texture.
- Texture: Healthy dormant grass feels dry but not brittle.
- Recovery: When watered, dormant grass should show signs of greening within a week.
How to Prevent Grass from Going Dormant?
While dormancy is natural, some homeowners prefer to maintain a green lawn year-round. Here are ways to prevent dormancy:
- Regular Watering: Provide consistent moisture, especially during dry spells.
- Proper Mowing: Keep grass at an optimal height to reduce stress.
- Soil Aeration: Aerate soil to improve water and nutrient absorption.
- Shade Management: Use shade covers to protect grass during extreme heat.

What Happens if You Overwater Dormant Grass?
Overwatering dormant grass can lead to root rot and fungal diseases. Excess moisture creates an environment conducive to pathogens, which can damage the lawn’s health. It’s best to water sparingly and only when necessary.
Can You Fertilize Grass in Dormancy?
Fertilizing dormant grass is not recommended. The grass cannot utilize nutrients effectively during dormancy, leading to potential nutrient runoff and environmental issues. Wait until the grass begins to green up before fertilizing.
How Long Does Grass Stay Dormant?
The duration of dormancy varies by grass type and climate. Cool-season grasses may go dormant for several weeks in summer heat, while warm-season grasses can enter dormancy in winter for a few months. Environmental factors like temperature and precipitation influence dormancy length.
Is Dormant Grass Dead?
Dormant grass is not dead; it is in a state of suspended growth. While it may appear brown and lifeless, the roots remain alive and can quickly resume growth when conditions improve.
What Are the Best Grass Types for Dormancy Resistance?
Certain grass species are more tolerant of dormancy conditions. Tall fescue, Kentucky bluegrass, and Bermudagrass are known for their resilience and ability to recover quickly from dormancy.
Conclusion
Caring for dormant grass involves a balance of minimal maintenance and strategic interventions. By understanding the needs of your lawn during dormancy, you can ensure it remains healthy and ready to thrive once it becomes active again.
