You can protect your grass seedlings from frost by covering them with frost blankets or straw mulch to provide insulation. Additionally, select frost-resistant grass varieties like Kentucky bluegrass and Bermuda grass for your lawn to ensure it thrives despite the cold.
In addition to exploring the impact of frost on seedlings, I will also cover key frost protection strategies, from opting for frost-resistant grass varieties to when you should consider seeking professional advice for frost protection.
Will Frost Kill New Grass Seed?
Frost doesn’t pose a severe threat to grass seeds, meaning it can’t kill them. However, it can interrupt the germination process of grass seeds by significantly delaying the emergence of grass seedlings.
According to the National Weather Service, frost can cause damage to plants when temperatures drop below 32°F (0°C), significantly reducing plant growth. Also, note that mild frosts can do minimal harm to grass seedlings, and extreme ones can do irreversible damage.
How to Protect Grass Seedlings From Frost: 8 Proven Strategies
Frost damage interrupts the plant’s ability to transport nutrients and water, explaining the discoloration, wilting, and death in severe situations.
Frost can also hinder photosynthesis, which is critical for plant growth, and this happens when it damages your grass’s chloroplasts. Consequently, understanding the devastating impact of frost on grass seedlings highlights the importance of efficient frost protection strategies.
Here are eight strategies that will help you protect your grass from frost in cold weather
1. Select Frost-Resistant Grass Varieties
Grass varieties like fescues and the Kentucky bluegrass are resilient to frost. These grass species can withstand and adapt to chilly temperatures.
Moreover, a British study on grass survival reveals that most grass species die when temperatures drop to -15°C (5°F), but the Kentucky bluegrass has a 25% survival at -15°C (5°F).
When selecting grass varieties for your lawn, frost resistance should be a vital consideration, primarily if you reside in regions that experience cold winters and spring frosts.

Mulch acts as an insulating blanket—maintaining a stable soil temperature. Moreover, it protects grass seedlings from extreme cold. Additionally, mulching is a proven method for safeguarding grass from frost.
You can opt for mulch if you fancy a natural insulator capable of creating a stable microclimate around the base of your grass seedlings.
Mulching also helps maintain even soil temperature, preventing rapid fluctuations that harm young grass seedlings.
Furthermore, mulch is a barrier between the ground and the chilly air—reducing the risk of direct frost exposure.
Organic mulch like wood chips, shredded leaves, and straws effectively act as natural barriers between frigid air and the ground.
5. Using Frost Blankets and Cloths
Designed to protect plants from frost damage, frost blankets and cloths are specialized covers that create a microclimate around seedlings.
Frost blankets and cloths trap heat and prevent frost from settling on grass seedlings.
These covers are usually made from lightweight and breathable materials that allow sunlight and air to reach your grass seedlings while offering protection against freezing weather.
To effectively use frost blankets and cloths, consider draping them over your grass seedlings before the onset of frosty weather.
Also, remember to secure the edges to the ground. This will ensure they stay in place throughout the night.
Here is the right procedure to use frost blankets and cloths to protect your grass seedlings from frost:
- Step 1: Prepare frost blankets or cloths.
- Step 2: Lay the blankets or cloths over the grass seedlings.
- Step 3: Secure the edges to the ground using stones or any heavy object to prevent wind from lifting them.
- Step 4: Ensure no gaps or openings could let frost in.
- Step 5: Remove the blankets or cloths in the morning once the frost has melted.
- Step 6: Store the blankets or cloths properly for future use.
6. Monitor Weather Conditions
