For a lawn to go dormant means that the grass temporarily stops growing and turns brown due to environmental conditions, such as cold or drought, to conserve energy. This natural process helps the grass survive unfavorable conditions and is common in many regions.
What Causes Lawn Dormancy?
Lawn dormancy typically occurs as a survival mechanism in response to extreme weather conditions. Understanding these causes can help you manage your lawn better.
- Cold Temperatures: In cooler climates, grass often goes dormant in winter. The cold weather slows down the growth process, and the grass turns brown as it conserves energy.
- Drought Conditions: During hot, dry summers, grass may also enter dormancy to survive with limited water. This is especially common in areas with water restrictions or naturally low rainfall.
- Nutrient Deficiency: While less common, a lack of essential nutrients can cause grass to go dormant. Ensuring proper fertilization can prevent this issue.
How to Identify Lawn Dormancy
Recognizing when your lawn is dormant is crucial for its maintenance. Here are some signs to look for:
- Brown or Yellow Grass: A dormant lawn often turns brown or yellow. This color change is a natural part of the dormancy process.
- Lack of Growth: If your lawn isn’t growing despite regular watering and care, it might be dormant.
- Firm Soil: Dormant grass often coincides with firm, dry soil, especially during drought conditions.
How to Care for a Dormant Lawn
Proper care during dormancy can ensure your lawn bounces back healthy and green. Follow these tips to maintain your lawn during this period:
- Limit Foot Traffic: Avoid walking on dormant grass to prevent damage, as it is more fragile during dormancy.
- Water Sparingly: Water your lawn only enough to keep the grass crowns from drying out. Overwatering can lead to disease and wasted resources.
- Avoid Fertilizing: Fertilizing during dormancy is ineffective and can harm the grass. Wait until the grass starts to green up again in the growing season.
When Will My Lawn Come Out of Dormancy?
The timing of when a lawn comes out of dormancy depends on the cause and environmental conditions. Typically, lawns revive when:
- Temperatures Rise: As spring approaches and temperatures increase, cold-dormant lawns begin to green up.
- Rainfall Returns: After a drought, lawns will come out of dormancy once regular rainfall resumes or when irrigation is increased.
Common Grass Types and Dormancy
Different grass types respond to dormancy in various ways. Here’s a look at some common types:
| Grass Type | Cold Dormancy | Drought Dormancy |
|---|---|---|
| Kentucky Bluegrass | Yes | Yes |
| Bermuda Grass | Yes | Yes |
| Tall Fescue | No | Yes |
How to Prevent Unnecessary Dormancy
Preventing dormancy when possible can keep your lawn lush and green. Consider these strategies:
- Regular Watering: Ensure your lawn receives about 1 inch of water per week, adjusting for rainfall.
- Proper Fertilization: Use a balanced fertilizer to provide essential nutrients, especially during the growing season.
- Aeration: Aerate your lawn to improve water and nutrient penetration, reducing stress on the grass.

How Long Can Grass Stay Dormant?
Grass can remain dormant for several weeks to a few months, depending on environmental conditions. Cold dormancy typically lasts through winter, while drought dormancy can vary based on rainfall and irrigation.
Is Dormant Grass Dead?
No, dormant grass is not dead. It is in a state of reduced metabolic activity to conserve resources. With proper care, dormant grass will revive when conditions improve.
Can I Mow a Dormant Lawn?
It’s best to avoid mowing a dormant lawn. Mowing can stress the grass further and cause damage. Wait until the grass begins to grow again before resuming regular mowing.
What Happens if I Overwater a Dormant Lawn?
Overwatering a dormant lawn can lead to fungal diseases and root rot. It’s important to water sparingly, just enough to keep the grass crowns hydrated.
How Do I Revive a Dormant Lawn?
To revive a dormant lawn, gradually increase watering and apply a balanced fertilizer once growth resumes. Ensure the soil is well-aerated and free of compaction to promote healthy growth.
Conclusion
