- 1). Test the pH range of the soil at least three months before planting new sod; it takes that long to amend the soil, if necessary. Dig a V-shaped 6-inch hole in the yard. Collect half of a cup of soil from the bottom of the hole. Follow the directions on the soil pH testing kit to verify the pH level of the soil. In order to properly absorb the soil's nutrients, vegetation must be planted in soil of a particular pH range. For example, ryegrass needs a soil pH range between 5.0 and 8.0. To amend the soil, spread lime over acidic soil (pH level under 5.0). Spread sulfur over alkaline soil (pH level over 7.0). Retest the soil in three months.
- 2). Grab a handful of soil and squeeze. Sod needs to be planted in well draining soil. If the soil crumbles, then it is sandy and too dry. Soil that releases water is generally waterlogged or clay soil. If the soil is malleable in the hand, then it is considered loam (rich soil suitable for planting), which has adequate draining abilities.
- 3). Spread 3 inches of builder's sand and compost over the soil and till into the soil to amend clay soil. Cover the yard with a 1/4-inch layer of peat moss and till into the soil to amend sandy soil.
- 4). Till the lawn area. Break up any large clumps of soil. Dig up any weeds on the lawn area. Push a lawn roller over the lawn area so that it is even. Add soil to any uneven areas.
- 5). Spray the soil with a mist of water right before planting. The soil should be moist but not too saturated. Saturated soil increases the chance of the new sod contracting root rot.
