How do you aerate and seed in the fall?

Fall is perfect due to the cool air temperatures and warm soil temperatures. Dethatching and aerating should be done before over-seeding to ensure the seed makes direct contact with the soil. Aeration is allowing air, water, and nutrients to circulate through your lawn by creating small holes in the soil.

Should I seed before or after aeration?

Within 48 hours after you aerate you should over seed, fertilize, and water your lawn. The seed, fertilizer, and water will have the best chance to get down into the holes made by the aerator if applied soon after aeration.

What is the best time to aerate and overseed?

Finally, there are still a lot of good growing days left ahead of winter. Therefore, the best time to aerate and overseed is in the fall. If you go that route, you end up with good new growth that’s already established when spring returns, ensuring a great start to the new season.

How do I prepare my lawn for aeration and overseeding?

Aeration + Overseeding for a Beautiful Lawn

To get started, make sure your lawn is watered, mowed short and then raked. Aerate your lawn to allow better water and nutrient absorption. Aeration is a process that allows the roots of your grass to breathe.

Will grass seed grow if I just throw it down?

Will grass seed grow if I just throw it down? Probably not. Some seeds on the soil’s surface will sprout, but the germination rate will diminish, and you will not be left with ideal results.

Is it too late to aerate in November?

Knowing when it is too late to aerate and overseed depends upon your grass type. For cool-season grasses, late fall and early winter are too late to do anything. For warm-season grasses, once the growing season has passed from late summer to early fall, it is not smart to take any actions.

Is it too late to overseed in November?

While November is not too late to plant grass seed, it is not without risks. Those risks can pay off with an easy planting season in the spring or it could mean the loss of your seeds if the weather warms up. We recommend following the planting guidelines on your grass seed for the best results.

Should I mow before I aerate my lawn?

Before you aerate, mow your lawn low (Timberline lawn experts recommend setting your mower to about 1.5-2 inches above the ground to maximize the effectiveness of aerating, being sure to not scalp the crown of the grass.) You will want to water one to three days before aerating.

Should I put topsoil over grass seed?

You can add a thin layer of organic matter to help the seed to germinate, but do not cover it over with top soil. ‘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. ‘

Can I seed a lawn in November?

It is now too late to sow grass seed, but new lawns can still be laid from turf if the weather is not too cold. Don’t feed the lawn with left-over summer feeds. These contain too much nitrogen, which stimulates lush growth; at this time of year, lush growth will be vulnerable to diseases.

What month is best to put grass seed down?

Plant cool-season grass seed in late summer or early fall (when daytime temperatures lower to about 60 to 75 degrees) for best success. September is typically the best month, although you might be able to get away with seeding as early as mid-August or as late as mid-October; it all depends on the forecast.

How long does it take for grass seed to germinate in October?

The seeds will take two to four weeks to sprout and during this time the ground should be kept damp. Proper watering one to two times a day is essential for a new lawn. This watering routine should be kept up until the grass sprouts are at least one inch tall.

Should you wet soil before planting grass seed?

The final step of site preparation for planting grass seed is to water the area well. Putting seed down on damp soil encourages speedy germination and provides immediate moisture to emerging roots. Wetting the area before planting is an important step in the process.

What temperature 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.

Can you sow grass seed in December?

Grass seed can be sown at any time of year but for best results, sow in autumn or spring. Seeds need warm, moist soil to germinate.

Will seed germinate in cold weather?

It’s All About Germination

Grass seed cannot flourish in cold soil because it requires warmth to germinate. But you should be aware that it’s not only cold weather that can interfere with growth. Extremely hot weather can also cause problems.

At what temperature will grass seed not germinate?

How cold is too cold for grass seed? Even the most cold-resistant cool weather grasses refuse to germinate once the soil gets below 50 degrees Fahrenheit.

Can I plant grass seed in October?

When it’s October, people often wonder if it is too late to plant new seed. The good news is if you hurry, seed can still be planted in October with the hope that it will survive the upcoming winter. Although September is the best time, often we can still plant grass seed up to October 15 with good results.

What is the best grass seed to plant in the fall?

Early fall is the best time to plant cool-season grasses, such as Fescue, Rye and Bluegrass. These grasses grow best when the temperature is between 60-80 degrees Fahrenheit, and benefit from the shorter days and cooler nights. There is also less competition from crabgrass and foxtails.

Will grass seed germinate on top of soil?

A common question that we get asked is “will grass seed germinate on the surface of the soil?” The simple answer to this is yes. In fact, it’s important not to bury your seed because the young grass shoots cannot break through if there is too much soil on top of them.

Should I mix grass seed with topsoil when overseeding?

The seed can be mixed with Lawn Topdressing and applied to the lawn jointly. This will save a bit of time and effort working the topdressing and seed into the surface. The seeded area must be kept moist, therefore, water your lawn after 2 or 3 days if no rain has fallen.

How do I prepare my lawn for seeding?

Prepare Your Soil

First, use a sharp shovel to remove any existing grass, or, if it is a large area, rent a sod cutter to get the job done faster. Then, take a walk around and inspect the area. Remove large rocks and debris, fill in low spots, and if your soil is compacted, work it over with a tiller.

Should you cover grass seed?

Grass seeds can germinate and grow if not covered as long the grass seed is kept moist. However, covering the grass seed with a thin layer of straw mulch, topsoil, or compost will help retain moisture and speed up the germination process.

What is the best thing to put on top of grass seed?

The best choice is green mulch, which is made from recycled paper, polymers (think of the moisture-holding capability that polymers give a baby diaper) and starter fertilizer.

Can you use too much grass seed?

Ignoring recommended seeding rates

Don’t overdo or cut corners. Too much grass seed causes undue competition for resources such as light, water and nutrients, and grass seedlings struggle as a result.
