Drought significantly impacts lawn dormancy by causing grass to enter a survival mode, reducing its growth and turning brown. This natural response helps the grass conserve water and energy during dry periods. Understanding how drought affects lawn dormancy can help homeowners manage their lawns effectively during dry spells.
What is Lawn Dormancy?
Lawn dormancy is a natural process where grass temporarily stops growing and turns brown to conserve resources. This usually happens during extreme weather conditions, such as drought or cold temperatures. Dormant grass is not dead; it is in a state of rest and can recover when conditions improve.
How Does Drought Cause Lawn Dormancy?
During a drought, water availability is limited, and grass responds by entering dormancy. This process includes:
- Reduced Growth: Grass slows down its growth rate to conserve water.
- Color Change: The grass turns brown as chlorophyll production decreases.
- Root Preservation: The grass focuses on maintaining root health over leaf growth.
How Long Can Grass Stay Dormant?
Grass can remain dormant for several weeks to months, depending on the grass type and drought severity. Cool-season grasses, like Kentucky bluegrass, can survive in dormancy for up to two months, while warm-season grasses, such as Bermuda grass, may last even longer.
How to Manage a Dormant Lawn During Drought
Proper management can help your lawn survive drought-induced dormancy:
- Limit Traffic: Reduce foot traffic to prevent stress on the grass.
- Water Wisely: Water deeply but infrequently to encourage deep root growth.
- Mow Correctly: Keep mowing heights higher to provide shade and reduce water loss.
- Avoid Fertilizing: Fertilizers can stress dormant grass; wait until it greens up.
Practical Example: Watering Strategy
A typical watering strategy during drought includes watering once every two weeks with about 1 inch of water. This approach encourages deeper root systems, making the grass more resilient.
Long-Term Lawn Care Solutions
Choose Drought-Resistant Grass Types
Selecting drought-resistant grass varieties can minimize the impact of future droughts. Some options include:
- Buffalo Grass: Requires minimal water and maintenance.
- Zoysia Grass: Tolerates drought and heat well.
- Tall Fescue: Known for deep roots and drought tolerance.
Implementing Xeriscaping
Consider xeriscaping, a landscaping method that reduces or eliminates the need for irrigation. This approach uses drought-tolerant plants and strategic design to conserve water.

How Can I Tell If My Lawn Is Dormant or Dead?
Dormant grass is usually brown but has firm roots. To check, pull on a patch of grass; if it resists, it’s likely dormant. Dead grass will come out easily and have brittle roots.
When Should I Water My Dormant Lawn?
Water your dormant lawn every two to three weeks with about 1 inch of water to keep the roots alive. Avoid overwatering, as it can lead to root rot.
Can I Revive My Lawn After Drought?
Yes, lawns can often recover from drought. Once regular rainfall resumes, water deeply and regularly, and consider overseeding to fill in any bare patches.
What Are the Signs of a Recovering Lawn?
A recovering lawn will start to show green shoots and increased growth. Consistent watering and proper lawn care will help speed up recovery.
Is It Better to Let My Lawn Go Dormant During Drought?
Allowing your lawn to go dormant can be a water-saving strategy. It reduces the need for frequent watering and helps the grass survive until favorable conditions return.
Conclusion
Understanding how drought impacts lawn dormancy is crucial for maintaining a healthy lawn. By implementing proper care strategies and choosing drought-resistant grass types, homeowners can ensure their lawns survive and recover from dry spells.
