How early can you plant grass seed in Illinois?
For Illinois, the best time to plant lawn seed mixture is mid-August to early September. If you've missed this time frame, you can also plant in April. You should avoid planting new grass in late spring or mid-summer because the full sun might damage it.
The absolute best time to seed or overseed your Illinois lawn is in the late summer to early fall (from mid-August to mid-September). This will give the young grass two or three months to get established before temperatures get too cold and growth stops.
About Overseeding a Lawn
In Illinois, the best time to overseed a lawn is late summer/early fall (late August to mid-September). Soil temperatures at this time of year are still warm, which promotes optimum seed germination, and the cooler air temperatures are better for grass growth.
If you have your heart set on planting grass in spring, early April is, in fact, the best time to do it. But, depending on where you live, spring seeding could come with complications.
Mid August to early September is the ideal time for seeding lawns in northern Illinois. April would be a second choice. Seeding in late spring through mid-summer often leads to problems as the summer heat slows or stops grass development of our cool season grasses.
Yes, you can plant grass seed too early in the spring. Planting too early in the spring can cause poor germination, which harms the growing seeds. As such, wait for the air and soil temperature to warm up enough to plant your grass seed.
Overseeding can help you get back to the thick, lush, green lawn you've always wanted. By spreading grass seed over your existing lawn, you can thicken up the thin areas, and your lawn will start to look terrific again. (This is different from reseeding, which is when you start over and plant a completely new lawn.)
Kentucky bluegrass is by far the most popular species used in home lawns in northern Illinois, due to high quality appearance, hardiness, and recovery ability. Kentucky bluegrass spreads by rhizomes.
Overseeding in spring is the next-best option. The weather should still be warm enough for the seeds to germinate, but be sure to get the seed in the ground and well established before the hotter summer temperatures and potential summer drought comes along.
Yes! A snowfall after you've planted grass seeds can actually be beneficial. It helps create a protective layer over the seeds and keeps them dormant. What can cause issues is a warm spell in winter, this can start the germination process and the new growth can struggle to cope when the temperature lowers again.
What month Should I reseed lawn?
The best time to reseed a lawn with cool-season grass seed is in the early fall, between mid-August to early October, and at least 45 days before the first fall frost.
The Turfgrass Water Conservation Alliance service recommends overseeding at least 45 days before your average first fall frost. In southern areas, overseed thinning lawns in late spring, as warm-season grasses enter active growth. For winter color, overseed southern lawns in fall.
Fall is the best time to introduce new seed into an existing lawn of cool-season grasses. But, depending on your grass type, overseeding in spring can yield good results, too, if it's done early enough in the spring to give seedlings enough time to mature before the onset of the summer heat.
Whether you're repairing bare spots, overseeding an existing lawn or starting from scratch, you can generally expect grass seedlings to emerge within seven to 21 days when grown under proper conditions. It may take another three to four weeks of growth before grass is long enough to mow.
Germination should take between seven and 10 days and seedlings will become established before the first severe frosts in late autumn, this is the preferred time as the roots establish better through the winter. Sowing seed in spring, grass will want to flower quite early before roots have established.
Will grass seed germinate on top of the soil? Yes; in fact, germination will suffer if too much soil is placed on top of the seeds. The experts at Jonathan Green recommend placing a thin layer of mulch or topsoil over them to help keep them moist and warm and promote growth.
Best time to attempt spring grass seeding
The best time to seed in the spring is mid-March through early April. Like fall seeding, the soil must first be prepared. The recommended method is verticutting. A verticut slices grooves in the soil that allows for the necessary seed and soil contact for germination.
Aim to seed early in the season, but wait until daytime temperatures are in the 60 to 75 degree Fahrenheit range. This roughly corresponds to the optimal soil temperatures for cool-season grass seed germination. Spring sunshine and rain both contribute to strong grass growth.
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. If it's too cold, the grass seeds will likely rot.
Three to six weeks are required for sprigs, stolons, and plugs to become established. For seeded lawns, wait for all of the seeds to germinate before mowing. For sod, sprigs, stolons, and plugs, make sure the roots are firmly planted in the soil before mowing to avoid tearing out new turf.
Is it better to cut grass or let it go to seed?
Allowing your lawn to go to seed isn't the best way to fill-in in thin patches. It can take months before the seed reaches maturity and as the plant focuses its energy on seed production, it may actually look like your lawn is thinning over time.
So, Will Grass Seed Grow if Not Covered? Grass seed can grow if not covered, but it is usually beneficial to add a layer of compost, topsoil or straw mulch over the top of your seed to keep it moist and help with germination.
Remove all debris and any wood, stones or large roots. Use a spade and garden rake to scratch the soil 1 to 2 inches at the surface, then dig about 6 inches deep to remove roots and rocks. Add seeding soil to the top of your existing soil and smooth with the rake.
They grow quickly and can be tough as nails to remove and dissipate from lawns. When you let your grass go to seed, you're actually letting weeds grow, eliminating any control you had over them. Mowing frequently cuts the weeds down and weakens them in their ability to grow back.
Consider mixing Kentucky Bluegrass, Fine Fescue, and Perennial Ryegrass in your cool-season Chicago lawn. You want Kentucky Bluegrass to be the dominant species in the mixture.
Fescue. Fescue Grass Seed is great for seeding both construction sites and residential landscapes. This cool-season variety germinates quickly, has good heat tolerance and typically grows well in both sun or shade.
Mixed Lawns
Lawns made up of mixed varieties can improve hardiness. Most sites are a mix of conditions, so a suitable grass would logically be a mix of grass varieties.
Is March too early to plant grass seed? In nearly all regions, March is too early to plant grass seed. Temperature is a better barometer; wait until days average about 80 degrees before planting grass seed for summer. March is too late to sow cool-season grasses.
Stop fertilizing for at least a month before overseeding. The fertilizer makes your grass grow faster, which makes it harder for the new seeds to take hold. Identify your grass type or the type of grass you want to grow.
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 put out grass seed in February?
Although September is the best time for lawn grass seeding, the second best time is usually mid-February to late March, depending on the weather. You should wait until there's no snow on the ground, and do the seeding when the ground is not frozen or muddy, so you can get some loose soil over the seeds.
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.
We don't recommend throwing down grass seed on the snow, since that leads to very uneven seed distribution when the snows melt and water runs down slopes and off the lawn.

50 pounds of Bermuda grass seed should cover approximately 50,000 square feet, which is well over one acre. However, if you are starting a new lawn with a grass like tall fescue or perennial ryegrass, your grass seed won't go as far. You will need about 10 pounds of grass seed per 1,000 square feet of lawn.
1. Overseed at the right time. Cool season seeds germinate when air temperatures are about 60 to 75°F, and when soil temperatures are about 50 to 55°F. Planting too early or too late in the season will lengthen the time it takes for the seeds to germinate, or prevent them from germinating at all.
If you put down too much grass seed, you will encourage competition that will cause your grass seedlings to struggle after germination because there will be excessive competition for sunlight, soil nutrients, and water. You'll know if you seeded too heavy when the grass grows in very thick patches.
THE BENEFITS OF OVERSEEDING
Overseeding newer turfgrass varieties into an older lawn can help it better withstand insects, disease, drought, shady conditions and heavy traffic. The investment in overseeding pays off by reducing the amount of fertilizer, water and pesticides required.
If your ambition is to have Perfect grass: perfectly flat, no weeds, no dead spots then over seed twice a year, every year. This keeps the turf thick, helps out compete weeds and doesn't take very long to do.
Can I overseed and fertilize at the same time?
Applying fertilizer at the same time you seed your lawn is not a recommended idea. Many experts will tell you that doing so you could risk to destroy a large part of your lawn where the soil was heavily fertilized.
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 type of seeds grow the fastest? Bermuda grass is the fastest-growing warm season grass, germinating in as little as 10 days. Ryegrass, which grows in cool climates, also germinates that quickly.
Use a “mist – lightly water – deeply water” process like this: After seeding and fertilizing, you'll want to keep the top inch of soil moist until the seeds start to germinate (aka sprout). This means misting the area once a day, maybe twice if it's unusually hot out there—but don't let the area get soggy.
If you have your heart set on planting grass in spring, early April is, in fact, the best time to do it.
Typically, germination takes between five and 10 days. Once germinated, the grass will continue to grow at a rate of about 2/3cm per week. We list some of the variables of grass seed germination below, plus tips on how to ensure successful, even germination, so you can grow the perfect lawn.
Sadly, there are no varieties of grass that birds don't like. From ryegrass to fescue, birds will find all grass seeds equally appealing. The only grass seeds they won't eat are the ones that have been covered in bird repellent.
Aim to seed early in the season, but wait until daytime temperatures are in the 60 to 75 degree Fahrenheit range. This roughly corresponds to the optimal soil temperatures for cool-season grass seed germination. Spring sunshine and rain both contribute to strong grass growth.
Kentucky bluegrass is by far the most popular species used in home lawns in northern Illinois, due to high quality appearance, hardiness, and recovery ability. Kentucky bluegrass spreads by rhizomes.
Half-hardy vegetables can be planted as early as 2 to 3 weeks before the average date of the last 32 freeze in the spring. Tender vegetables should be planted from the time of the last average 32 freeze to one week later. Very tender crops should be planted 2 to 3 weeks after the last average 32 freeze.
Can you plant grass seed right before winter?
As a general rule, plant cool-season grass seed at least 45 days before the estimated date of your first fall frost, before soil and air temperatures drop to less favorable levels. Your grasses will enjoy a full fall season, plus a second cool growing season come spring.
Bermuda grass is a warm-weather perennial2, meaning it flourishes in spring and summer, and grows back annually. This grass seed from Sta-Green contains a premium blend of 99 percent weed-free Bermuda grass. The germination period is longer than other species (about two to three weeks).
Chicago falls into zone 5, with a low average temperature of -20°F to -10°F. More often than not, you will find a label on plants indicating that the plant is “hardy up to zone x.” Additionally, websites often categorize plants by zone.
This is called a Plant Hardiness Zone. Southern Illinois is in Zones 6a-7a. Central Illinois is in Zones 5a-6a. Northern Illinois is in Zones 5a-5b.
Yes, Yes, Yes! April is finally here meaning that your garden soil is finally warming up! April is the best time to plant most of your vegetable seeds after your last frost for all zones. It's still not too late to plant tomatoes and peppers from seeds as well!
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.
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.
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.
