Covering grass can help prevent frost damage, but it’s important to do it correctly. Frost occurs when temperatures drop below freezing, causing ice crystals to form on grass blades, which can lead to damage. By using protective coverings, you can insulate the grass and reduce the risk of frost damage. Read on to learn effective methods for covering grass and protecting your lawn from frost.
How Does Frost Damage Grass?
Frost can cause significant damage to grass by freezing the water inside plant cells, leading to cell rupture and browning. This often results in a patchy, unhealthy lawn. The extent of damage depends on the grass type, temperature, and duration of frost exposure.
What Are the Best Materials for Covering Grass?
Using the right materials is crucial for effectively covering grass and preventing frost damage. Here are some recommended options:
- Frost Blankets: Lightweight and breathable, these are specifically designed to protect plants from cold temperatures.
- Burlap: A natural and reusable option that provides insulation while allowing air circulation.
- Old Sheets or Blankets: A cost-effective solution for small areas; ensure they are lightweight to avoid crushing the grass.
- Plastic Sheets: These can trap moisture and lead to fungal growth, so use them with caution and remove during the day.
How to Properly Cover Grass to Prevent Frost?
To effectively cover grass and protect it from frost, follow these steps:
- Check Weather Forecasts: Cover your grass before a frost warning is issued.
- Choose Appropriate Materials: Select from frost blankets, burlap, or old sheets.
- Cover in the Evening: Place coverings over grass in the late afternoon or early evening to trap warmth.
- Secure the Edges: Use rocks or stakes to hold coverings in place, preventing wind from blowing them away.
- Remove in the Morning: Take off coverings once temperatures rise to allow sunlight and air to reach the grass.
What Are Additional Tips for Frost Protection?
In addition to covering your grass, consider these strategies to minimize frost damage:
- Water the Lawn: Moist soil retains heat better than dry soil, so water your lawn a day or two before frost is expected.
- Mow Higher: Keep grass slightly longer during the frost season to provide natural insulation.
- Avoid Fertilizing Late in the Season: Fertilizing in late fall can encourage new growth, which is more susceptible to frost damage.

What Types of Grass Are Most Susceptible to Frost?
Warm-season grasses like Bermuda and St. Augustine are more susceptible to frost damage compared to cool-season grasses such as fescue and ryegrass.
How Does Frost Affect Other Plants in My Garden?
Frost can damage a wide range of plants, including tender annuals and perennials. Consider covering these plants with similar materials to protect them.
