3 Cost-Effective Ways to Protect Grass Seedlings from Frost

Premature grass seeds are very sensitive to frost.  A young grass seed doesn’t have a mature and deep root inside the soil. So a heavy frost is a big obstacle in growing. A hard frost can freeze the soil and seeds. 

As a result, young seeds don’t get proper nutrition. A mature grass can survive freezing but an immature seedling can’t survive. A good mixture of fertilizer and precautions can help to grow more green grass.

Now, you may be wondering, Does Frost kill grass seedlings?

Well, Young and immature grass seedlings die in frosting.  Make sure you have taken protective precautions while sowing seeds in frost.

If you have sowed seeds in frost then maintain selective ways to protect them from freezing. An easy and cost-effective way can help seedlings to grow with thriving nutrition. Here are the ways-

Watering the Lawn

Watering your lawn can prevent freezing. Wet soil produces heat to avoid freezing. Make sure that you give water before it begins to get cold. For the best result, water your seedlings before night. The evening is the best time for watering grass seedlings. 

Watering in the evening resists cold overnight. To resist over freezing, set an alarm or add water at night. Add light warm water at night to avoid the extra frost. This warm water will give extra value to your seedlings.

Avoid Roaming Over the Lawn

Don’t walk aimlessly over your seedling lawn. Walking and driving over the lawn can damage the seed. Do not walk in the morning over your seedling lawn. Because that time frost forms freezing blades in the grass. 

Walking over the grass can kill the seedlings. Don’t let the people or animals step on the grass lawn as it kills the cellular level of seedlings. To protect new grass seedlings, make everyone aware of the lawn. Add a  stop banner on the side of the lawn.

Make an alternative way of walking or diving. Bend the way away from the sowed grass seedlings area.

Wrap the Seedling

Since the frost can kill the seedlings, covering the seedlings is a mature decision. Covering the baby plants is an incredible method to secure the germination process from frost. 

During the cold nights, add a black plastic tarpaulin sheet to cover the grass seedlings. Other plastic polythenes are enough to use for protecting the newborn grass. Cover the plastic before evening cold. Because midnight frost inhibits the most growth of baby plants.

Air can make plastic fly. To tighten the plastic cover, Tie a knot and weighted down it with a stone tying in every corner of the plastic. This is an amazing way to secure your young grass seedlings from freezing. In the early morning, remove the tarpaulin to chase the sunlight. Let the seedlings take a warm morning after a freezing night.

Many people have queries about which season and time are best for grass seedlings. We’ll let you know the questions and answers in a precise form which may help you to know exactly what you want. So here are the questions and answers –

Will Frost Stop the Growth of Grass Seedlings?

No, but the grass seedling will remain dormant. Dormant means the grass seedling will stop its growth for a certain period. If the temperature is between  50-70 degrees F then the seed will sprout again. Later on, this will enhance its growth when the temperature becomes normal. Second fall frosting is a critical time for young seedlings to grow. Maximum time in this period, seeds don’t grow. They remain dormant under the soil. 

Can I Mow My Lawn after frosting?

The frosting makes freeze blades on grass. So it will be a bad idea to mow the lawn in the winter season.  But mowing the lawn is good for the grass. To maintain a good layout of grass, routinely mowing is necessary. For the new grass seedling, mowing is a very substandard idea. So it’s better to avoid mowing the lawn in frosting. Because premature grass can lose its strength to grow after mowing. 

Should I Fertilize the Soil in Frosting?

Fertilizing the soil is an impressive idea. But try to use compost before frosting. Choose the autumn season to humus the soil. Because winter dewdrops and topdressing mix well to produce healthy grass on the lawn. Extra nutrition will be generated by adding fertilizer to the soil.

Can I Sow Grass Seeds after the First Fall of Frost?

Sowing grass seed during the winter is an inferior decision. Continuous frosting can kill the young grass. The subsequent frosting is vulnerable to grass seedlings. As the first frost is the combination of cold and winter vibe so sowing grass seeds is okay. But in the second frost, cold increases than normal winter temperature. Try to sow at least 6 weeks before the first frost.

Does Straw save grass seedlings?

Yeah, it protects the grass seedlings from frost. It covers the grass and absorbs the frost water. It generates warmth for sprouts. Straws resist extra coldness to seeds. Choose the best quality of straws and you can add some water in the evening. As water can reduce the frosting and increase the temperature.


  • Make a walkway or driveway to avoid the seedling lawn.
  • Use Fertilizer to enhance the growth of grass seedlings.
  • Sow the seeds before the winter season. So that at least they have a deep root.
  • Try to sow the seeds in the warm season when the temperature is above 70 degrees Fahrenheit.

Final Verdicts

A Winter season is very vulnerable to new grass seeds. Low temperature inhibits the growth of seedlings. They remain in a dormant period. After getting a normal temperature like 50-70 degrees Fahrenheit, they again get their fuel to grow. As young seeds are delicate, covering the lawn with plastic tarpaulin is the best idea to protect the grass seedlings. Keep in mind that newborn seedlings need extra supervision to grow.
