Although September is the best time, often we can still plant grass seed up to October 15 with good results. The problem with late season seeding is that Mother Nature is working against us. Shorter days and cooler temperatures prolong the germination of the seed and its establishment.
Is it too cold to plant grass seed at 40?
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.
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.
What month should I plant grass seed?

When should you throw grass seed down?

Will grass grow in 45 degree weather?
What Temperature is Right for Laying Down Grass Seed?

If the soil temperature is much lower than 50 degrees, however, the seeds will lay dormant and not germinate.
Should you water grass seed when it’s cold?
The colder weather does not evaporate moisture from the lawn as quickly as it does in the warmer weather.
