Lawn blankets, also known as frost blankets or turf covers, can be effective in preventing winter browning of your lawn. These blankets provide a protective layer that helps to insulate grass from harsh winter conditions, such as frost and snow, thereby maintaining its health and color throughout the colder months.
What Are Lawn Blankets and How Do They Work?
Lawn blankets are typically made from lightweight, breathable materials like polypropylene or polyester. They are designed to cover your lawn and protect it from extreme weather conditions. By trapping heat and moisture, they create a microclimate that is more favorable for grass survival.
Benefits of Using Lawn Blankets
- Insulation: Keeps soil temperatures stable, reducing the risk of frost damage.
- Moisture Retention: Helps maintain soil moisture levels, preventing dehydration.
- UV Protection: Shields grass from harmful UV rays during sunny winter days.
- Pest Deterrence: Can help reduce damage from pests by acting as a barrier.
How to Use Lawn Blankets Effectively
- Timing: Apply before the first frost to ensure maximum protection.
- Coverage: Ensure the blanket covers the entire lawn area, with edges secured to prevent wind lifting.
- Maintenance: Regularly check for damage or displacement and adjust as needed.
- Removal: Remove during warm spells to prevent overheating and allow for natural sunlight exposure.
Do Lawn Blankets Prevent All Types of Winter Damage?
While lawn blankets are effective against frost and snow, they may not fully prevent damage from other winter stresses, such as heavy foot traffic or poor drainage. It’s important to combine their use with proper lawn care practices, such as aeration and appropriate watering.
Practical Example: A Case Study
A study conducted in Minnesota showed that lawns covered with frost blankets retained their green color longer compared to uncovered areas. The grass under the blankets experienced less browning and showed quicker recovery in spring, demonstrating the effectiveness of these covers in cold climates.

How Do Lawn Blankets Compare to Mulching?
Mulching provides a layer of organic material over the soil, which can also insulate and retain moisture. However, lawn blankets offer better protection against frost and are easier to remove in spring.
Can Lawn Blankets Be Used on All Types of Grass?
Yes, lawn blankets can be used on most grass types. However, warm-season grasses may benefit more as they are more susceptible to cold damage.
Are There Any Alternatives to Lawn Blankets?
Yes, alternatives include mulching, using winter fertilizers, and selecting cold-resistant grass varieties. Each method has its benefits and can be used in conjunction with lawn blankets for optimal results.
How Long Should Lawn Blankets Be Left On?
Lawn blankets should be left on throughout the winter but removed during warm spells to prevent overheating and to allow sunlight exposure.
Do Lawn Blankets Require Special Storage?
Store lawn blankets in a dry, cool place to prevent mold and mildew. Roll them up neatly to avoid creases and damage.
