Caring for dormant grass is essential to ensure a lush, green lawn once the growing season returns. Dormant grass, whether due to winter cold or summer heat, requires specific care to maintain its health and vitality. Understanding the seasonal needs of your lawn can prevent damage and promote robust growth.
What Is Dormant Grass?
Dormant grass is grass that has temporarily stopped growing due to environmental conditions. This typically occurs during extreme temperatures, such as the cold of winter or the heat of summer. During dormancy, grass turns brown and appears dead, but it is still alive and capable of regrowth when conditions improve.
How to Care for Dormant Grass in Winter?
Winter dormancy is common in cool-season grasses like Kentucky bluegrass and fescue. Here’s how to care for your lawn during this period:
- Avoid Heavy Traffic: Limit walking on the grass to prevent compaction and damage to the roots.
- Clear Debris: Remove leaves and debris to prevent mold and disease.
- Water Sparingly: Watering is generally unnecessary unless there is a prolonged dry spell. Ensure the soil doesn’t completely dry out.
- Fertilize Appropriately: Apply a winterizing fertilizer in late fall to provide nutrients for the spring growth.
How to Care for Dormant Grass in Summer?
Warm-season grasses such as Bermuda grass often go dormant during extreme heat. Here’s how to manage summer dormancy:
- Water Wisely: Water deeply but infrequently, about once a week, to encourage deep root growth.
- Mow High: Keep grass blades longer to shade the soil and reduce evaporation.
- Avoid Fertilization: Do not fertilize during dormancy, as this can stress the grass.
- Minimize Traffic: Like winter dormancy, avoid heavy foot traffic to prevent stress.
Common Mistakes to Avoid
- Overwatering: Excessive watering can lead to root rot and other fungal diseases.
- Improper Mowing: Cutting grass too short can expose roots and increase stress.
- Neglecting Pests: Dormant grass can still suffer from pests, so monitor and control infestations.
Practical Tips for Lawn Maintenance
- Soil Testing: Conduct a soil test to understand nutrient needs and adjust fertilization accordingly.
- Aeration: Aerate the lawn in the fall or spring to improve air and water flow to the roots.
- Mulching: Use mulch around trees and shrubs to retain moisture and regulate soil temperature.

How Long Can Grass Stay Dormant?
Grass can remain dormant for several weeks to months, depending on the climate and grass type. Cool-season grasses typically stay dormant in winter, while warm-season grasses can endure summer dormancy.
Does Dormant Grass Need Fertilizer?
Fertilization is generally not recommended during dormancy. Instead, fertilize before dormancy begins to provide nutrients that support the grass when it resumes growth.
Can You Revive Dormant Grass?
Yes, dormant grass can be revived with proper care. Gradually increase watering as temperatures stabilize and ensure proper mowing and fertilization practices to encourage growth.
What Temperature Causes Grass to Go Dormant?
Cool-season grasses enter dormancy when temperatures fall below 50°F, while warm-season grasses go dormant when temperatures exceed 90°F for extended periods.
Is Brown Grass Always Dormant?
Not always. Brown grass may indicate dormancy, but it can also be a sign of disease, pests, or improper care. Assess the situation and address any underlying issues.
Conclusion
Caring for dormant grass requires understanding its seasonal needs and adjusting your lawn care practices accordingly. By following these guidelines, you can protect your lawn during dormancy and ensure a healthy, vibrant return to growth.
