How cold is too cold for overseeding?
50°F
If you’re wondering how cold is too cold for grass seed germination use our rule of thumb and check the weather reports. If the daytime temperature is below 60°F then soil temperature is below 50°F, making it too cold; if there is frost or still a danger of frost, then it’s too cold.
Can I just throw grass seed down on existing lawn?

Can I plant grass seed in January?
Dormant seeding is the process of seeding your lawn after the normal growing season. The seeds will be ready to become little baby grass plants when the weather conditions are right. We dormant seed when the weather will be consistently cold, under 40 degrees. December and January are ideal.
Will grass seed grow in December?
During the winter months, temperature and moisture levels are not at optimal levels for lawn seed germination, but this isn’t always viable and reseeding in winter is still very much possible with a bit of know-how and the right type of seed.
Will grass seed still grow if it freezes?
Grass seed will not sprout in freezing temperatures. This is a protection method developed by grass plants. Frozen ground is too hard for grass seedlings to send their roots into, so any grass seeds that sprout in freezing cold would quickly die.
Should I mix grass seed with topsoil when overseeding?
Should you mix grass seed with topsoil? If you’re looking for a quick answer, yes, you should mix grass seed with topsoil for small areas of your garden and other applications.
Can you sprinkle grass seed on top of soil?
Grass seed spread on top of the soil will still attempt to grow, but you will get poor results compared to grass seed that has been covered with 1/4 inch of soil. Uncovered seed is prone to drying out, being eaten by birds, or carried away by water runoff.
Will grass seed germinate if nights are cold?
Daytime temperatures around 60 to 75 degrees Fahrenheit typically mean the soil temperature is between 50 and 65 degrees and perfect for seed germination. If the soil temperature is much lower than 50 degrees, however, the seeds will lay dormant and not germinate.
Can I put grass seed down in February?
What is the best time to reseed my lawn? The ideal time to reseed your lawn is between mid-February and October, but Winter Green Grass Seed extends the season whilst ever the soil temperature is over 5 degrees.
Can I plant grass seed if it freezes at night?
If temperatures reach freezing at night, do not spread grass seed. Warm days and cold nights are deadly conditions for grass seedlings. Track soil temperatures in your area to make sure they are well above freezing before you plant grass seed.
What is the lowest temperature grass seed will germinate?
If soil temperature drops below 9 degrees, it can get too cold for regular grass seed to grow. The ideal soil temperature for grass seed germination is 9-12 degrees and just like any seed, grass seed needs the right conditions, with warmth and moisture the key to germination.
Is it OK to plant grass seed in December?
Grass seed can survive the winter, and planting during the winter season is known as dormant seeding. If you put down grass seed in November or December, the seed will just lay dormant until the soil starts to warm in spring. While this comes with risks, it can also be beneficial and save you time on seeding in spring.
Is Morning Dew enough for grass seed?
Moisture from morning dew keeps the seed bed moist and the less intense sun rays slow the rate of evaporation. The soil temperatures are still warm and the cool rains make it the perfect time to create that beautiful lawn that your neighbors will envy as they look over your fence.

Missed a Day of Watering Grass Seed: What Happens? In most cases and for most grass seeds, missing a day of watering will not kill it. However, if the ground dries out, and it most likely will to a sufficient degree, the grass seed will halt its germination process.
Can you overwater new grass seed?
There are two things to always remember for watering new grass seed: Not enough water will kill the sprout. Too much water can leave less than ideal results, as well.
Can grass seed be buried too deep?
Most species should be planted at a shallow depth of ¼ to ½ inch. Larger seeds can be planted up to 1 inch deep. Most seedings are too deep if you cannot see a few seeds on the soil surface.
Will heavy rain ruin grass seed?
Planting grass seed on a dry day is more pleasant than working in the rain, but you don’t have to schedule your planting to avoid rain. Newly planted grass seed needs considerable moisture to germinate, so rain after planting won’t kill it. Heavy rains may lead to soil erosion and could wash the seeds away.
When should I stop watering new grass seed?
You can stop watering new grass seed daily once it has germinated and the grass blades measure to about 1 inch. This should take between 3-4 weeks from planting. Once you’ve reached this stage, you can water your new grass seed with approximately 1 inch of water 1-2 times a week.
Should you put topsoil over grass seed?
Do not put top soil over grass seed, but you can add a thin layer of organic matter to help the seed to germinate. ‘Never put topsoil over newly planted grass seed,’ says Yamaguchi. ‘This won’t provide healthy growing conditions – it will actually prevent the seedlings from sprouting by essentially suffocating them.
Should I rake grass seed into soil?
Remember, lawn grass seeds only need to be lightly raked into the soil, or even just scattered directly on the soil surface. Any seeds buried more than the length of the seed will have a hard time germinating successfully.
