Without any extra actions, some grass seeds will grow. It's important to cover your grass seed with mulch while reseeding bare patches of your lawn. The seed would be exposed to the weather if the grass seed is not covered by existing turf. As long as the grass isn't too sparse or sandy, the seeds can be slightly better covered. It's tempting to just spread some grass seed in your yard.
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.
Despite the harsh treatment, some grass seeds will grow on top of soil surface will sprout, but the germination rate will decline. The grass's roots would therefore have a tough time establishing themselves properly, and the grass will ultimately die because it is not as resilient as it should be. And your investment and hard work will be wasted.
Why Grass Seed Neef To Be Covered
Why Seed Should Not Be Exposed to the Weather
Certain things must happen for any type of seed to germinate. The seed must be moist and wet to sprout. Grass seed is difficult to sprout if there isn't enough water. Any seed will dry out without any form of mulch or top-dressing.
Even if seeds germinate, they can fail to develop a good root system. Too shallow roots in the ground often prevent the grass from having access to moisture and nutrients.
Grass Seed vs. Bird Food
Leaving seeds out in the soil will make them a perfect food source for birds. Grass seed covers can help protect them from wildlife and have a higher chance of not being consumed if they are shielded. Read also How to Stop Birds From Eating Grass Seed
Grass seed takes two to four weeks to germinate, so during that time, it doesn't have roots to anchor it. Grass seed that isn't covered is quickly swept up and carried to a sewer drain.
Best Way To Cover Grass Seed
Spreading Straw Over Grass Seeds
One of the most common materials used as grass seed cover is straw. It's a cost-effective alternative, but pick one that's free of weed-producing seeds. Straws of oat, rye, and barley are all healthy alternatives. Since pine straw produces terpenes, which can affect the growth of surrounding plants, it can be a problem.
Compost is an excellent grass seed cover. Kitchen scraps, leaves, lawn clippings, and wood chips may all be used to produce compost. However, it should be finely screened so that it can quickly break down and transfer nutrients to the seedlings.
Mulch To Cover Grass Seed
If you want to retain moisture in new grass seeds, mulch is another good choice. 1/4-inch sawdust, soft peat moss, or torn newspaper are all good choices. A biodegradable seed mat isn't going to slip down a hill. Along with the plants, it has its mulch.
Straw, fertilizer, mulch, and other soil additives may all be replaced with polyethylene film. It's simply a huge sheet of plastic that you spread over seeded areas and protect with stakes or big rocks. To prevent the soil from being too wet, use a transparent sheet instead of black or another dark color.
When and How to Cover
Cover and water the grass seed as soon as you've sown it. Spread one bale of straw every 500 square feet by using straw. When using fabric as grass seed cover, simply unroll it over the grass seed and protect it with tent spikes at the corners.
It can be difficult to get grass to grow after seeding a new lawn (read also How to Plant Grass Seed). The seeds can not get enough moisture and may dry out if there is no grass to support them. Grass seed cover will help keep them moist and protect them from drying out. It's important to use the correct material to cover your new grass seed. You can choose from a range of effective materials to suit your lawn and your budget.
