Managing lawn dormancy due to weather involves understanding the natural cycle of grass and taking proactive steps to maintain lawn health. This ensures your lawn remains resilient and recovers quickly when conditions improve. Here are the best practices to manage lawn dormancy effectively.
What Causes Lawn Dormancy?
Lawn dormancy is a natural survival mechanism for grass, typically triggered by extreme weather conditions such as heat, drought, or cold. During dormancy, the grass conserves energy and resources by slowing down its growth. Understanding these triggers can help you manage your lawn better.
- Heat and Drought: During hot, dry summers, grass may turn brown as it conserves water.
- Cold Temperatures: In winter, grass may go dormant to protect itself from freezing temperatures.
How to Manage Lawn Dormancy in Hot Weather
When temperatures rise and rainfall decreases, lawns can enter a dormant state. Here’s how to manage your lawn during these conditions:
- Water Wisely: Water deeply but infrequently to encourage deep root growth. Aim for watering early in the morning to minimize evaporation.
- Mow High: Keep your mower blades high (3-4 inches) to provide shade and reduce water loss.
- Limit Traffic: Reduce foot traffic on the lawn to prevent stress on dormant grass.
- Avoid Fertilization: Fertilizing during dormancy can stress the grass. Wait until the lawn is actively growing again.
Best Practices for Winter Lawn Dormancy
In colder climates, lawns often go dormant in winter. Here are some tips to care for your lawn during this period:
- Clear Debris: Keep the lawn free of leaves and debris to prevent mold and diseases.
- Minimize Salt Damage: Use sand or kitty litter on icy walkways instead of salt, which can harm grass.
- Aerate Before Winter: Aerating in the fall can improve drainage and reduce soil compaction, helping the lawn recover faster in spring.
How to Revive a Dormant Lawn
Once favorable conditions return, you can help your lawn recover from dormancy with these steps:
- Gradual Watering: Slowly increase watering frequency to help the grass green up.
- Fertilize Appropriately: Apply a balanced fertilizer to provide essential nutrients for recovery.
- Overseed Thin Areas: Reseed any bare or thin spots to encourage new growth.
- Monitor for Pests and Diseases: Dormant lawns are vulnerable to pests; treat any infestations promptly.

How Long Can a Lawn Stay Dormant?
Grass can remain dormant for several weeks to months, depending on the weather conditions and grass type. Warm-season grasses typically tolerate longer dormancy periods than cool-season varieties.
Does Dormant Grass Need Water?
Dormant grass still requires some moisture to survive. Watering once every three to four weeks during prolonged drought can help keep the roots alive.
Can You Mow Dormant Grass?
It’s best to avoid mowing dormant grass. If mowing is necessary, keep the blades high to avoid stressing the lawn further.
What Are Signs of a Dead Lawn vs. Dormant Lawn?
A dormant lawn will have brown grass but will still feel firm and resilient when walked on. A dead lawn, however, will have brittle, straw-like grass that pulls up easily from the soil.
When Should I Fertilize My Lawn After Dormancy?
Fertilize your lawn in early spring for cool-season grasses and late spring for warm-season grasses, once the grass begins to show signs of active growth.
Conclusion
Managing lawn dormancy due to weather involves understanding the natural cycles of grass and taking specific actions to protect and nurture your lawn.
