Is it Too Late to Plant Grass Seed in November? | Jonathan Green (2024)

The answer to this question is: not necessarily. While planting grass seed in November is too late to make the fall growing season, there is a method called dormant seeding.

Through dormant seeding, grass seed can be planted in November when the weather is cold enough to keep it dormant until the weather warms up in the spring. Once spring arrives, the seeds will sprout and grow normally. Dormant seeding is done to save time in the spring and to save waiting until the ground warms up to prepare the soil.

The Process of Dormant Seeding

Dormant seeding is done exactly the way you would lay down seed in the spring or fall, it is simply done in winter. Ideally you want to lay down seed at a time when it will be quickly covered by a layer of snow. This will not only protect the seeds but ensure that they will stay dormant. There is a risk associated with dormant seeding and that is if the weather unexpectedly warms up through the winter. If the weather warms up to activate the seeds, they might sprout and the seedlings will not survive when the weather turns cold again.

The only difference between dormant seeding and seeding in the fall or early spring is the time. The soil needs to be prepared to support the new seeds once they come out of dormancy. First, the pH of the soil must be tested. This will let you choose the right brand of Mag-I-Cal® for Lawns in Acidic Soil to use to correct to pH to the right level for seed germination. The ideal range is between 6.2 and 7. For soil that is above this range, use Mag-I-Cal® Plus for Lawns in Alkaline & Hard Soil and for soil that is below, use Mag-I-Cal® for Lawns in Acidic Soil.

After treating the pH level, the soil should be fed with Love Your Soil®. This product makes the soil biologically healthy to support the growing root system. It also loosens the soil to allow the roots to grow deep into the soil.

The seed is put down over the prepared soil using a spreader. If there are bare spots the seed will need to be raked in after being put down. The seeds must have contact with the soil and be covered by about a quarter inch of soil for proper germination.

What Seed Should You Use?

Just like with preparing the soil you should pick the same seed for dormant planting that you would use for planting at other times during the year. Seed should be high-quality with no fillers. Black Beauty grass seed from Jonathan Green is the result of over 100 years of innovation and research.

Black Beauty® Original Grass Seed is known for its waxy coating which is similar to the coating you would find on a fresh apple. The coating protects the grass from disease and helps seal in moisture to protect against drought. The roots of Black Beauty grass reach up to four feet deep into the soil, far deeper than other grass varietals. It is also entophytic which makes it naturally insect resistant. It is the choice of sod growers around the country.

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. For more grass seed tips and advice visit Jonathan Green online or your local independent retailer.

FAQs

Is it Too Late to Plant Grass Seed in November? | Jonathan Green? ›

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 November too late for grass seed? ›

If you've missed that window, but you still want to conduct seeding practices this fall, my recommendation is to wait until November to seed. This practice is called “dormant seeding” and is certainly an effective way to introduce new species and/or varieties of turf into your existing lawn.

What's the latest you can plant grass seed? ›

The best time to plant new tall fescue and bluegrass seed is in early to mid September. 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.

Does grass still grow in November? ›

Most cool-season grasses can still flourish comfortably in temperatures below 50 degrees Fahrenheit but gradually stop sprouting as it approaches 32 degrees. That usually starts to happen in late November or early December.

Will grass grow in 40 degree weather? ›

The ideal temperature range for grass seed is between 55-85°F (12-29°C). Anything below 55°F (13°C) will inhibit the growth of your grass seeds, so it's important to keep an eye on the weather forecast when planting.

What temperature kills 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.

Is November too late to aerate and overseed lawn? ›

For warm-season grasses it is too late to aerate once the growing season has passed in late summer into early fall. For cool-season grasses, late fall into early winter is too late to aerate.

Can I just throw grass seed on bare spots? ›

Can I Just Throw Grass Seed on Bare Spots? Throwing grass seed onto bare spots will result in little-to-no germination and will not help to repair lawn spots. If you want to fix patches on grass, you need to properly prepare the bare spots before laying down the seed.

Can I just throw grass seed down on an existing lawn? ›

Overseeding is spreading grass seed over an existing lawn. Done right, it's a straightforward process that gets results. As grasses mature, thinning is normal—especially if you enjoy your lawn and use it often. Overseeding keeps your lawn competitive and steeped in youth and vigor, without starting over from scratch.

What happens if you plant grass seed too late in the fall? ›

The grass will be thinner, allowing more contact between the soil and your seeds. In late fall the ground is cold enough to keep the seeds from germinating until spring. If they germinate this late in the season the seedlings will be too young to survive the winter conditions.

Will new grass seed survive the winter? ›

A series of warmer days could cause the seed to break dormancy and begin to germinate; if that period is followed by more freezing weather, tender new seedlings would be damaged or killed. But where winters are consistently cold, dormant seeding may take place anytime during the months of November through February.

What to put on your lawn in November? ›

Continue to mow cool-season grasses until they stop growing. Rake lawns and remove debris. Recycle leaves as mulch. November is the traditional time to apply a winterizing fertilizer to your lawn (higher potassium and phosphorus, and lower nitrogen).

How often should I water my grass seed in November? ›

Normally a lawn should be watered deeply but infrequently, but when you are watering for new grass seed, you must water every day. Set automatic timers for about 5 to 10 minutes, early in the morning, and again at mid-day. Watering done by hand or hose-end sprinklers must be consistent and evenly applied.

Can you plant grass seed if it freezes at night? ›

'It is recommended to wait until the ground has thawed and the soil temperature has risen above freezing before planting grass seed after a frost,' says Shawn Denny. 'Also, it's essential to ensure that the soil is not too wet or waterlogged, as this can also inhibit seed germination.

Should I water grass seed if it's cold? ›

The colder weather does not evaporate moisture from the lawn as quickly as it does in the warmer weather. Most lawn experts recommend watering your grass until the soil or ground temperature reaches the 40-degree Fahrenheit mark.

How long can grass seed lay dormant in the winter? ›

Dormant seeding is a collective term for overseeding lawns in late fall and winter when soil temperatures are too cold to allow grass seed to germinate. In the mid-west, the opportunity for dormant seeding is best from mid-November through early March, while soil temperatures remain below 50 degrees.

What months are best to put grass seed down? ›

The best month to put grass seed down depends on the type of grass you have and where you live. The best time to plant grass seed for cool-season grasses is in early fall or around September. For warm-season grasses, late spring or early summer (May to June) is the optimal time.

What is the best late season grass seed? ›

Cool-season grasses such as Kentucky bluegrass, perennial ryegrass and tall fescue, including Kentucky 31 tall fescue, grow most vigorously during the cool temperatures of late summer and early fall.

Can I fertilize my lawn in late November? ›

Timing: Apply fall lawn fertilizer once between August and November, right before winter hits, 6 to 8 weeks after the summer feeding.
