What to Do for Clay Soil to Plant Grass Seed

Clay is made up of small particles that stick together and cling to moisture. The heavy substance limits root spread and development. Clay soil is not ideal for growing grass, but with some amendments, it can make a decent surface.
  1. Preparation

    • Prepare the planting area to loosen up the thick clay soil and promote root development. Remove debris and till to a depth of 4 to 6 inches. Spread 12 oz. of hydrated lime per square yard to make the clay take on a more neutral pH.

    Considerations

    • Make the clay more fertile with sand and compost. The substances will improve drainage, dry it out a bit and add air pockets.

    Care

    • Use a starter seed fertilizer to balance the nutrients in the clay dirt and help the seed root more quickly. Broadcast the seed evenly over the area with a spreader. Keep the soil moist until the grass sprouts, but avoid overwatering the clay because it has a tendency to hold onto moisture.
