Whoops. You missed the best time to seed your lawn and now the temperatures are too cold to do so. There isn’t enough time to establish new grass before Winter comes but you desperately need grass by next Summer. Have no fear, try dormant seeding. Never heard of dormant seeding? It’s a great alternative to lawn installation for those who missed the prime window for a grass seed lawn. Dormant seeding is the process of spreading grass seed during the time of year when seeds won’t germinate (dormant). This time of year, is typically late Fall to early Winter in Minnesota because the outside temperature drops below 50 degrees. The method used is like any other grass seeding method, but watering and maintaining the seed isn’t necessary after it’s been sown. This method is perfect for those who missed the seeding window of early Fall, or are trying to get an early start for next Spring. The time of year when temperatures are cold enough to dormant seed in Minnesota is late October to early December. Once the soil temperature drops below 50 degrees, grass seed no longer will germinate. Seed that is put down will sit dormant over the Winter underneath all the snow. When the temperature rises in Spring, the snow will melt, and the grass seed is already in place to start growing right away. The process of dormant seeding is basically the same as if you were to seed during Spring, Summer, or Fall. Soil needs to be prepared by loosening it up and clearing debris (dead grass, weeds) so the seed can be spread on the bare dirt. A slit seeder is a machine commonly used for larger applications. It will make a shallow slit in the ground that the seeds rest in. Once the seeds are sown, make sure they are watered. With conventional seeding, continual watering and maintenance would be necessary for proper growth. But with dormant seeding, the seeds can be left alone until Spring. The fact that the seeds don’t germinate immediately would normally be viewed as a negative. However, dormant seeding can be very effective when done properly. One of the most important components of growing grass from seed is the contact between the seed and soil. Over the course of winter the ground will freeze, thaw, shift, and heave. All this movement allows the seeds to settle into the soil rather than sit on the surface. The cooler temperatures and snow coverage also help to keep the soil moist when the seeds start to sprout in the Spring. Hopefully all your Fall chores are complete; including your sprinkler system winterization. But if there is one last chore to take care of, try dormant seeding. This process can be very tricky though, so calling a professional is your best bet at a lush green lawn. For those who missed the prime window for a grass seed lawn but need to fix their lawn, dormant seeding will give you a head start on your lawn next Spring.What is dormant seeding?

Dormant Seeding For Lawn Installation - Last Chance At a Healthy Lawn? ›
Once the soil temperature drops below 50 degrees, grass seed no longer will germinate. Seed that is put down will sit dormant over the Winter underneath all the snow. When the temperature rises in Spring, the snow will melt, and the grass seed is already in place to start growing right away.
How effective is dormant seeding in lawns? ›Dormant seeding works best when you want to reseed bare soil areas or help thicken up thin lawns. It is not as effective where lawns are thick and dense because good seed-to-soil contact is necessary for the grass seeds to germinate and grow next spring.
What temperature is dormant seeding? ›If power raking is used, go over the turf lightly only deep enough to penetrate the top ¼” of soil. Once seedbed preparation is done, dormant seeding should ideally take place from mid-December through mid-February. Soil temperatures must be 40° degrees F or below to ensure seeds will not germinate.
What happens if you plant grass seed too late? ›Grass that is seeded late can die as a result of the cold harsh conditions, or due to drying out. Freezing and thawing of the soil, coupled with a lack of moisture, leaves the tender roots and crowns susceptible to desiccation. Seeding late into the season still requires the same steps.
How do you reseed a bad lawn? ›- Clear the area. Kill weeds and any remaining poor-looking grass with a non-selective herbicide about 2 weeks before you want to seed your lawn. ...
- Prep for success. ...
- Select your grass seed. ...
- Spread your grass seed. ...
- Feed for growth. ...
- Water daily.
Will grass seed grow if you just throw it on the ground? Definitely yes! Hand-sowing is the simplest method if you only need to cover a few spots. Take a handful of seeds and spread them over the dead patch, or better yet, involve your kids and introduce them to some basic gardening chores.
Are dormant seeds viable? ›Seed dormancy is defined as a temporary failure of a viable seed to germinate in conditions that favor germination, whereas seed longevity is defined as seed viability after dry storage (storability).
Will grass seed germinate on top of soil? ›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.
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.
How long does it take for seed dormancy to break? ›High-temperature treatment: Incubation at 40-50 °C for a few hours to a few days may have an effect in overcoming dormancy in some species. For instance, rice seeds treated with hot water at 40°C for at least 4 hours.
Can I put down grass seed in June? ›
Other plants and grasses in the garden will begin to go dormant just as they are coming up, meaning less competition for nutrients. Warm weather grass seed should be sown anytime from early spring to mid-summer, presuming the temperature is over 65°F each day.
Can you just sprinkle grass seed on lawn? ›If you simply toss the grass seed onto the soil, you will end up with poor germination. Thoroughly rake the area to remove any loose debris and to create grooves in the soil. These grooves will help increase the seed-to-soil contact that is imperative for germination.
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 you put too much grass seed down? ›Quality grass seed labels include guidance on optimal seeding rates to maximize your results. 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. Too little seed leaves lawns thin or bare.
When should you not reseed your lawn? ›The moisture and warm air are beneficial to grass growth but there are a few things about spring that make it less than ideal for reseeding. Spring provides a good environment for crabgrass and weeds to begin germinating, which causes grass to have to compete for the nutrients it needs to thrive.
What are the best thing to do if seeds are dormant? ›- Mechanical Scarification.
- Hot Water Scarification.
- Drop into hot water (77 to 100oC), remove from heat, allow to cool and soak for 24 hours.
- Acid Scarification.
- Seeds, in small batches, are brought into contact with 93% Technical Grade sulphuric acid. ...
- Warm Moist Scarification.
Many species of plants have seeds that delay germination for many months or years, and some seeds can remain in the soil seed bank for more than 50 years before germination. Seed dormancy is especially adaptive in fire-prone ecosystems.
What is the difference between overseeding and dormant seeding? ›What is the difference between dormant seeding and overseeding? Dormant seeding is done when established turf is dormant during cold temperatures, usually between December and Mid-March. Overseeding can be done at any time during the year while the grass is actively growing.
How long do dormant seeds last? ›How Long Will Seeds Last? Many seeds will maintain great germination for three years even in your kitchen cupboard, though there are exceptions. Stored well, some seeds can last centuries. Reducing humidity is key to storing seed, reducing risk of mold and pre-mature sprouting.
