Best Sod for Shallow Soil (6 Inches Over Rock)

Most grass roots concentrate in the top 6–8 inches, so 6 inches of soil is adequate. Kentucky bluegrass and tall fescue are both good choices. Bluegrass forms a dense, attractive sod and handles sun well. Tall fescue is deeper-rooted and more drought-tolerant. Avoid fine fescues in full sun and perennial ryegrass if water is limited. Kentucky bluegrass is a personal favorite for its texture and recuperative ability.
