Are there specific grass varieties that handle dormancy better? Yes, certain grass varieties are better at handling dormancy due to their inherent characteristics. These grasses can survive periods of extreme temperatures by going dormant, a survival mechanism that conserves water and energy.
What Is Dormancy in Grass?
Dormancy in grass is a natural process where grass temporarily stops growing to survive adverse weather conditions, such as extreme heat or cold. During dormancy, grass may turn brown, but it is not dead; it is conserving resources until favorable conditions return.
Which Grass Varieties Handle Dormancy Best?
Cool-Season Grasses
Cool-season grasses thrive in cooler climates and are known for their ability to handle dormancy during the hot summer months.
- Kentucky Bluegrass: Known for its lush appearance, Kentucky Bluegrass goes dormant in high heat but recovers quickly when temperatures drop.
- Perennial Ryegrass: This grass is fast-growing and can withstand dormancy during heatwaves, making it ideal for transitional zones.
- Tall Fescue: With deep roots, Tall Fescue is more drought-tolerant and can remain dormant for extended periods without damage.
Warm-Season Grasses
Warm-season grasses excel in hotter climates and handle winter dormancy well.
- Bermudagrass: This popular Southern grass goes dormant in cold weather but thrives in heat, making it a favorite for lawns and sports fields.
- Zoysiagrass: Known for its dense growth, Zoysiagrass handles both summer heat and winter dormancy effectively.
- St. Augustinegrass: While it prefers warmth, St. Augustinegrass can survive dormancy during cooler months and quickly regains its lush green color.
How to Care for Dormant Grass?
Proper care can help your lawn survive dormancy and recover quickly:
- Limit Watering: Overwatering dormant grass can lead to disease. Water sparingly unless there is an extended drought.
- Avoid Fertilizing: Fertilizing during dormancy can stress the grass. Wait until it shows signs of active growth.
- Minimize Traffic: Reduce foot traffic to prevent damage to the grass blades and roots.
- Mow Sparingly: Keep mowing to a minimum, and set the mower blades higher to avoid stressing the grass.
Benefits of Choosing Dormancy-Resistant Grasses
Selecting grasses that handle dormancy well offers several benefits:
- Water Conservation: Dormant grasses require less water, reducing your lawn’s water usage.
- Resilience: These grasses are more resilient to weather extremes, ensuring a healthier lawn.
- Cost-Effective: Reduced need for maintenance and watering saves time and money.

People Also Ask
How long can grass remain dormant?
Grass can remain dormant for several weeks to months, depending on the variety and climate conditions. Cool-season grasses may stay dormant through hot summers, while warm-season grasses can endure dormancy during cold winters.
Is dormant grass dead?
No, dormant grass is not dead. It has temporarily stopped growing to conserve resources. Once favorable conditions return, the grass will resume growth and regain its green color.
Can I overseed dormant grass?
Yes, overseeding dormant grass can be beneficial, especially for cool-season grasses. This practice can help fill in bare spots and improve the lawn’s overall density once growth resumes.
How do I know if my grass is dormant or dead?
To determine if grass is dormant or dead, gently tug on a section of grass. If it resists and remains rooted, it’s likely dormant. Dead grass will pull out easily as the roots are no longer viable.
Should I water dormant grass?
Watering dormant grass is generally unnecessary unless there is an extended drought. In such cases, provide occasional deep watering to prevent root damage.
Conclusion
Choosing grass varieties that handle dormancy well is crucial for maintaining a healthy and resilient lawn. By understanding the dormancy characteristics of different grasses and providing appropriate care, you can ensure your lawn thrives despite seasonal challenges.
