Depth for Grass Seeds in the Soil

Soil Testing

• Take a sample of your soil to your local University Agriculture Extension to have it tested. The office will determine whether the soil is alkaline or acidic, and its fertility. If your soil needs to be amended before planting the grass seed, the office will give you recommendations. The test ensures that the seed that you plant will have a chance to germinate, grow and remain healthy.

Soil Preparation

• Use a rototiller to break up the soil at least 6 inches deep. If you need to amend the soil, layer the material over the soil before you start tilling the soil so you can work the material into the soil. Remove any rocks and debris so the soil is free of obstructions that could block root growth into the soil.

Sowing Seed

• Sow the grass seed on top of the soil using your hands or a lawn spreader. Do not cover up the seed after sowing it. If you have concerns about birds eating the seed, use clean, weed-free straw or cheesecloth to cover the seed. If using straw, use a light layer so you can see some dirt. Do not bury the seed with straw. The cheesecloth allows light through but hides the seed from birds.

Irrigation

• Water the seed lightly whenever the soil becomes dry. Do not soak the soil. When planting grass seed, you need to keep the soil and seed moist, but if you overwater the seeds and soil, you can wash away the seed, especially if the seed is planted on a slope or slight incline. Keep the soil moist until the grass blades are at least 2 to 3 inches high.
