The still-warm soil of late August, September, October, or November encourages optimum root growth, while the cooling air temperatures discourage excessive top growth. This is perfect for establishing lawn grasses and promoting extensive root growth.

Can you lay down too much grass seed?

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.

What happens if I put grass seed down too early?

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.

How do I prepare my lawn for seeding?

Do I need to put dirt over grass seed?

Very little soil is actually needed to cover the seeds, typically about ¼- inch, so simple raking will do the trick. If the seeds are not properly protected by existing grass or a thin layer of topsoil, they may dry before germination or be washed away by rain.

Will grass seed grow if thrown on top of dirt?

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.

Will grass clippings help new grass grow?

Simply put, grass clippings are good for lawns because they turn into natural fertilizer. Clippings contain the same things as the rest of your grass – including water and the nutrients (especially nitrogen) that your lawn needs to stay healthy.
