Did you miss the optimum time for seeding this fall? If you are wondering when that was, typically in our region (Northwest Indiana and Southwest Michigan) the number 1 very best time to plant grass seed is between August 15 and September 15.
It’s November 4th, 2021 and we are still getting daily customer questions about seeding at this time of year and it’s really too late and would be a waste of time and money. Mother Nature is not going to let your seed grow enough to make it through a frost and our soon-to-come harsh cold temperatures.

Any grass seed planting after September in our region can be risky due to freezing ground temperatures. Once the seed germinates in anywhere from 3 days to 3 weeks (more on germination can be read HERE), it will need a couple more weeks to mature enough to withstand the freezing and often unpredictable Indiana temperatures so planting too late may not be successful.
TOO LATE AND NOT FEELING GREAT ABOUT WAITING UNTIL SPRING?
THERE’S A SOLUTION!
Why not step out of your comfort zone and opt for what is often referred to as a “dormant seeding“? Using the method of “dormant seeding” also happens to typically be the 2nd best option timing-wise to plant grass seed in our region.
“Dormant seeding” simply refers to the fact that if you put the seed down once the ground is frozen for the season, the seed will lie dormant or inactive until soil temperatures are warm enough to germinate in the EARLY spring and give you a head-start compared to doing the seeding in the spring.
You can use any seed you want to use for this method of seeding.
Unsure what seed to choose? Pick a high-quality seed for best results.

For good timing on a dormant seeding, we typically suggest waiting until December and getting it done prior to March, but it all depends on ground and air temps. Basically, you want to wait until the ground has frozen and will stay that way until spring so that the seed you put down stays dormant the entire time. If we were to have a warm-up spell for a length of time, the seed MIGHT start the germination process a bit, and then become vulnerable to being killed off once the freezing temperatures return.
You will need to make sure your site is prepared for seeding prior to snow fall, as you would a typical spring or fall seeding.
Starter fertilizer is not needed, since the grass is not actively growing, but be sure to get some fertilizer (without crabgrass or broadleaf herbicides!!!) down after the ground thaws to help give the new seedlings a good spring boost.
Simply broadcast the seed at the rates recommended, sit back (enjoy a hot chocolate) and wait for spring.
Sound strange? How does it work? When the ground freezes and thaws during the winter months, the earth heaves and cracks, eventually making room for seed to fall into the soil where it will wait in a DORMANT STATE for warmer weather to germinate in the spring.
Some challenges to consider with dormant seeding (overall, less challenges than spring though!):
- Birds love seed and since food is scarce in the winter you may get some visitors. You might try seeding in the later winter months (February or early March) for better results.
- If we get an early sprig warm-up followed by winter settling back in again, there is potential for snow or freezing AFTER the seed has started to germinate.
- You won’t be able to use certain herbicides — such as pre-emergent crabgrass herbicides — until after the new grass’s roots system has grown enough to have been mowed at least 2-3 times.
Unsure about trying a dormant seeding? Try sodding instead.
We harvest sod well into November and sometimes as late as December. The cooler months give off just the right amount of hydration so little water is needed during this time. As long as the site is prepared, you can lay it on frozen ground, the sod will go dormant, and it will “wake up” and finish rooting in the spring. (Surprising, huh?)

I have a grass runway I seeded this past fall with Kentucky 31. It was seeded October 13. The grass is coming, but thin. Can I overseed it, dormit seed it? What grass seed would you recommend? When I seed it? Also, I struggle with turkeys on the runway. Eager for your thoughts. Thanks
You may call our office at 574-232-6811 to discuss your questions.
On the other hand, if you are not located in Northern Indiana / Southern Michigan, we’d actually recommend you contact a sod farm or University Extension Office in your area. Every region has different circumstances, and you want to talk to the experts in your unique region for the most reliable information.
Thanks for asking! – Lisa, Red Hen Turf Farm
The most optimal grass planting season for warm season grasses can be done in late Spring, specifically mid-March through April. Cool-season grasses for seeding a lawn in fall require ambient soil temperatures (60-70°F) to be able to germinate.
Thanks so much for sharing!
You made a good point that I should also consider how certain birds would be attracted to my property if I have good grass. I’d like to look for bluegrass for sale because I’m thinking about finding a good way to make my lawn feel more verdant. Starting with the grass will be a good idea.
