Seed germination blankets provide a way to re-seed bare spots in the lawn with an increased chance of success. Germination blankets allow light and water to reach seeds underneath them so they will sprout. Blankets also warm the soil to germinate seeds more quickly. … Loosen the soil about 2 inches deep to aerate it.

What is the purpose of the germination table?

How do you seed and straw a lawn?
