Grass Seed Germination

Grass Seed Germination

Grass seeds will germinate successfully in normal soils when the surface temperature of the soil does not go below 50 degrees, and where the daytime soil temperature exceeds 60 degrees. Grass seeds also need adequate moisture and adequate sunlight. The best time to plant, therefore, is when the daily soil surface temperature exceeds 60 degrees, and when there is adequate soil moisture to keep the soil moist throughout germination.
