Grass seed needs the correct soil and air temperature, as well as moisture content, to sprout. Planting it too early in the spring can result in less-than-ideal germination, because the seeds can die off or become unproductive.
How cold is too cold for grass seed?
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.

What temperature will kill grass seed?
Generally, warmer temperatures are more harmful to the seeds. Damages from heat and humidity affect the grass seed’s growth. Temperatures above 100 degrees Fahrenheit are strong enough to harm them. Under 140 degrees Fahrenheit or hotter can kill them within a short period of exposure.
Can I plant grass seed if it freezes at night?
In late winter, the ground typically freezes and thaws with every night/day cycle. Grass seed will not germinate until the soil reaches about 55 degrees, so you don’t have to worry about your grass starting to grow and then being frozen — it won’t happen.
Will grass seed germinate at 40 degrees?
Will Grass Grow in 40 Degree Weather? Although some mature cool-season grasses will not enter full dormancy until soil temperatures reach 40℉ (4℃), growth will slow to almost a complete stop by this point. Cool-season grass seed cast in 40-degree weather likely won’t sprout.
Is it OK to overseed in the spring?
If you live in the North and are unable to overseed in the fall, your next best time is the spring. If you live in the South, the best time to overseed is late spring through mid-summer, since warm-season grasses need warmer soil temperatures to germinate.
What month should I plant grass seed?
Although you can sow grass seeds at any time of the year, it is best to sow in spring or autumn where possible. In the autumn you can expect fewer problems with weeds and the rain will make it easier to keep the seedbed moist and the soil temperature will still be high.
How do I plant grass seed in spring?
Plant Grass Seed Put half the grass seeds in a drop or broadcast spreader. Turn the rake so the tines are facing up. Cover the ground with a thin layer of mulch made from wheat straw, if your lawn is uneven and prone to erosion. Water the lawn lightly each day until the grass is 2 inches tall.

Will frost kill new grass seedlings?
The easy answer is that frost will not kill grass seed, but that does not mean that you should plant grass seeds when there is danger of frost. While the seeds will survive until the next growing season, any seeds that sprout into seedlings will not.
Is 30 degrees too cold for grass seed?
We dormant seed when the weather will be consistently cold, under 40 degrees. December and January are ideal. The cold weather allow for the seeds to lay dormant in the soil, waiting for temperatures to warm up, usually in late March. August and September are still the best months to seed.
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 it too cold to plant grass seed at 50 degrees?
What Temperature is Right for Laying Down Grass Seed? 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.
What happens to grass seed if it snows?
Snow Halts Grass Seed Germination The reason is that most seeds need warmer temperatures to germinate, and snow halts the germination of seeds altogether. Grass seeds in snow will simply lie there until temperatures rise, so seeding earlier in the season will yield better results.
