Good soil preparation is essential for healthy sod grass growth. By following these guidelines, you’ll be on your way to a beautiful lawn.
Begin by removing any surface rocks or debris. We recommend adding mulch (1 cubic yard per 1,000 square feet) and finely-ground gypsum (50 pounds per 1,000 square feet) to create a healthy soil. Till in soil amendments to a depth of 4″ to 6.” Now is also the best time to install your sprinkler system. As you are working the soil additional debris may appear which should be removed.
Work the soil to create a level surface for installation. Water heavily to compact the soil, then use a roller as a final step to eliminate any air pockets. This will reduce settling which will lead to an uneven surface. Your final grade should be 1/2″ – 1″ below walkways, and 1/2″ below sprinkler heads.
