Is it normal for a lawn to go dormant in summer? Yes, it is entirely normal for certain types of grass to enter a dormant state during the summer months, especially in regions experiencing high temperatures and low rainfall. This natural process helps the grass conserve energy and water, reducing stress on the lawn.
Why Does Grass Go Dormant in Summer?
What Causes Lawn Dormancy?
Lawn dormancy is primarily caused by environmental stressors such as heat and drought. When temperatures soar and water becomes scarce, many grass types enter a dormant phase to survive. During this time, the grass may turn brown and appear dead, but it is usually still alive and will recover when favorable conditions return.
Which Grass Types Are Prone to Summer Dormancy?
Not all grasses respond to summer heat in the same way. Cool-season grasses, such as Kentucky bluegrass, fescue, and ryegrass, are more likely to go dormant in summer. These grasses thrive in cooler temperatures and struggle in the heat, prompting them to conserve resources by going dormant. In contrast, warm-season grasses like Bermuda, zoysia, and St. Augustine are better adapted to heat and may remain green and active during the summer.
How to Manage a Dormant Lawn
Should You Water a Dormant Lawn?
Watering a dormant lawn can help keep the grass alive, although it may not turn green until temperatures drop. Providing about 0.5 to 1 inch of water every two to three weeks can prevent the roots from dying. However, over-watering during dormancy can lead to disease and other issues, so it’s crucial to strike a balance.
Tips for Maintaining Your Lawn During Dormancy
- Limit Foot Traffic: Avoid walking on the lawn too much, as dormant grass is more susceptible to damage.
- Mow Sparingly: If you must mow, set your mower to the highest setting to avoid stressing the grass.
- Avoid Fertilizing: Fertilizing during dormancy can harm the grass. Wait until the grass begins to green up in the fall.
When Will My Lawn Recover?
A dormant lawn typically begins to recover when temperatures drop, and regular rainfall resumes. Cool-season grasses will start to green up in the fall as cooler, wetter conditions return. The recovery process can take a few weeks, depending on the severity of the dormancy and the care provided during the summer.

How Can I Tell if My Lawn is Dormant or Dead?
To determine if your lawn is dormant or dead, try the "tug test." Gently pull on a patch of grass. If it resists and stays rooted, it’s likely just dormant. If it pulls out easily, the grass may be dead. Dormant grass will also have a firm root system, while dead grass will have dry, brittle roots.
Can I Prevent My Lawn from Going Dormant?
While you can’t entirely prevent dormancy, you can minimize its effects. Water your lawn deeply but infrequently to encourage deep root growth. Aerate the soil to improve water absorption and consider overseeding with drought-resistant grass varieties to maintain more green coverage.
Is Dormancy Beneficial for My Lawn?
Yes, dormancy is a natural defense mechanism that allows grass to survive adverse conditions. It conserves resources and reduces stress, helping the lawn recover more robustly when conditions improve.
What is the Best Time to Water My Lawn?
The best time to water your lawn is early in the morning, between 6 a.m. and 10 a.m. This timing reduces evaporation and allows the grass to absorb the moisture before the heat of the day.
How Long Can a Lawn Stay Dormant?
A lawn can remain dormant for several weeks to a couple of months, depending on the grass type and environmental conditions. As long as the roots remain healthy, the grass can survive extended dormancy and recover when conditions improve.
Conclusion
Understanding lawn dormancy can help you maintain a healthy lawn throughout the year. While it may be disheartening to see your lawn turn brown in the summer, remember that this is a natural response to environmental stress. By providing minimal water, reducing stress, and waiting for cooler weather, your lawn can bounce back and thrive.
