How to Plant Grass Seed in Thin Soil

By James Clark ; Updated September 21, 2017

Thin soil is characterized by fine, shallow soil that sometimes grows over sheets of rock or slate. In order to plant grass seeds in thin soil, one must ensure that the soil is not too clumped or dry. Treating the soil with a fertilizer mixture before planting seeds will help more durable grass grow in your lawn. Planting grass seeds in thin or fine soil is a simple process that does not require specialized horticulture or gardening skills.

Clear debris in the area you want to plant grass seeds. Collect and dispose of leaves, twigs, and debris in a trash bag.

Put on your gardening gloves. Use your spade or shovel to begin tilling or digging up the soil in the area where you want to plant the grass seeds.

Feel the soil between your fingers to determine whether it is clumpy. Large clumps of soil should be broken up with your spade or shovel; small clumps (the size of a quarter) are fine.

Add fertilizer to dry, thin soil. When adding fertilizer, add 3 cups of product for every square yard of soil.

Incorporate the soil and fertilizer well using your spade or shovel.

Plant the grass seeds in the ground. Cover the grass seeds with at least 3 inches of soil mixture. Pat down with shovel or spade.

Water the area. Do not overwater; the soil should be wet, but not drenched or flooded. Water the seeded area once weekly during the fall and spring and 2 to 3 times per week in the summer, depending on how dry your climate is.
