Lawn covers are protective materials used to shield grass and plants from harsh weather conditions, particularly frost. These covers act as a barrier, retaining heat and moisture, which helps prevent frost damage. By using lawn covers, you can extend the growing season and safeguard your garden during colder months.
What Is a Lawn Cover?
A lawn cover is a type of fabric or material placed over plants and grass to protect them from adverse weather conditions, such as frost. These covers are typically made from materials like polypropylene, polyethylene, or natural fibers. They are designed to trap heat from the soil, creating a microclimate that can be several degrees warmer than the surrounding air.
Benefits of Using Lawn Covers
- Frost Protection: Lawn covers insulate plants from freezing temperatures.
- Moisture Retention: They help maintain soil moisture levels by reducing evaporation.
- Extended Growing Season: Covers enable earlier planting in spring and prolong growth into fall.
- Pest Control: Some covers can also deter pests by acting as a physical barrier.
How Do Lawn Covers Protect Against Frost?
Lawn covers protect against frost by creating a warm microenvironment around the plants. When placed over the garden, these covers trap heat radiating from the soil. This trapped heat prevents frost from forming on the plants, which can cause cell damage and ultimately harm or kill the plants.
Types of Lawn Covers
| Type | Material | Best Use |
|---|---|---|
| Floating Row Covers | Polypropylene | Frost and pest protection |
| Burlap | Natural fibers | Winter protection for shrubs |
| Plastic Sheeting | Polyethylene | Short-term frost protection |
- Floating Row Covers: Made from lightweight polypropylene, these are ideal for protecting plants from frost and insects.
- Burlap: This natural fiber cover is perfect for wrapping shrubs or small trees to shield them from winter winds and frost.
- Plastic Sheeting: Provides short-term protection but should be used with caution to prevent overheating during sunny days.
How to Use Lawn Covers Effectively
To maximize the benefits of lawn covers, follow these steps:
- Choose the Right Material: Select a cover based on your specific needs—frost protection, pest control, or moisture retention.
- Secure the Edges: Use stakes, rocks, or soil to anchor the edges and prevent wind from lifting the cover.
- Monitor Weather Conditions: Remove covers during warm days to prevent overheating and allow for pollination.
- Inspect Regularly: Check for tears or damage to ensure the cover remains effective.

How Long Should Lawn Covers Be Used?
Lawn covers should be used as long as there is a risk of frost. Typically, this means covering plants overnight and removing them during the day when temperatures rise above freezing.
Can Lawn Covers Be Used for All Plants?
Most plants can benefit from lawn covers, but it’s essential to ensure the cover is appropriate for the plant type. Delicate plants may need additional support, while hardier species might not require as much protection.
What Are the Alternatives to Lawn Covers?
Alternatives to lawn covers include mulching, which insulates the soil, and using windbreaks like fences or hedges to reduce exposure to cold winds.
Do Lawn Covers Affect Plant Growth?
Lawn covers can positively impact plant growth by protecting against frost and pests, thus allowing for a longer growing season. However, improper use, such as covering during warm weather, can inhibit growth.
How Do I Choose the Right Lawn Cover for My Garden?
Consider the climate, plant types, and specific needs of your garden. Lightweight row covers are versatile, while burlap is better for larger plants needing winter protection.
