Grass typically turns brown or yellow when it goes dormant. This change is a natural process that occurs when grass conserves energy during unfavorable growing conditions, such as extreme cold or drought. Understanding grass dormancy can help homeowners maintain healthy lawns and make informed decisions about lawn care.
Why Does Grass Turn Brown When Dormant?
Grass enters dormancy as a survival mechanism. During dormancy, grass conserves its resources by reducing its metabolic activity. This process is triggered by environmental factors such as:
- Temperature Extremes: Cold weather in winter or heat in summer can lead to dormancy.
- Water Scarcity: Drought conditions cause grass to conserve moisture.
- Daylight Changes: Shorter daylight hours in winter can also trigger dormancy.
How Long Does Grass Stay Dormant?
The duration of grass dormancy depends on the climate and grass type. Generally, grass can remain dormant for several weeks to months:
- Cool-Season Grasses: These grasses, like Kentucky bluegrass, go dormant in hot, dry summer months and revive in cooler temperatures.
- Warm-Season Grasses: Varieties such as Bermuda grass may go dormant in winter, reviving in spring.
How to Care for Dormant Grass
Proper care during dormancy ensures grass returns healthy when conditions improve. Here are some tips:
- Limit Watering: Water sparingly to prevent root rot, unless there’s an extended drought.
- Avoid Fertilizing: Fertilizing dormant grass can waste resources and harm the lawn.
- Minimize Traffic: Reduce foot traffic to prevent damage to fragile dormant grass.
Can You Revive Dormant Grass?
Reviving dormant grass involves patience and proper care. Here are steps to help grass recover:
- Regular Watering: Once conditions improve, water deeply to encourage root growth.
- Mow High: Keep the grass a bit taller to shade the soil and retain moisture.
- Aerate: Aeration helps improve soil conditions and encourages root growth.
How to Differentiate Dormant Grass from Dead Grass
It’s crucial to distinguish between dormant and dead grass:
- Dormant Grass: Appears brown or yellow but has a firm root system. It will recover with improved conditions.
- Dead Grass: Feels brittle and pulls up easily from the soil, indicating a need for reseeding or replacing.
What Types of Grass Are More Prone to Dormancy?
Different grass types respond to environmental stress differently. Here’s a quick comparison:
| Grass Type | Dormancy Season | Ideal Climate | Resilience to Stress |
|---|---|---|---|
| Kentucky Bluegrass | Summer | Cool | Moderate |
| Bermuda Grass | Winter | Warm | High |
| Tall Fescue | Summer | Cool to Warm | High |

Is Dormant Grass Bad for My Lawn?
Dormant grass is not harmful; it’s a natural survival strategy. Proper care during dormancy ensures a healthy lawn once conditions improve.
Can Grass Go Dormant in the Rainy Season?
Grass typically does not go dormant during the rainy season unless temperatures are extreme. Instead, it may grow more vigorously due to ample water supply.
What Are Signs of Grass Coming Out of Dormancy?
Signs include new green shoots, increased growth rate, and a softer texture. Regular watering and proper care can support this transition.
Should I Cut Dormant Grass?
It’s best to avoid mowing dormant grass. If necessary, mow at a higher setting to prevent stress and damage.
