When installing sod, what should be rolled immediately after initial watering?

When installing sod, rolling the entire area immediately after initial watering serves several important purposes that contribute to a successful sod installation. First, rolling helps to ensure good soil-to-sod contact. This is essential because a proper bond between the sod’s roots and the soil allows the grass to establish more effectively. Good contact minimizes air pockets that can impede growth and development.

Additionally, rolling the entire area helps to level any uneven sections of the sod, which can prevent water from pooling and promote an even distribution of moisture. It also aids in settling the sod down into the soil, enhancing the absorption of water and nutrients, and promoting healthy growth.

Focusing on the perimeter, edges, or corners alone does not provide the same comprehensive benefits as rolling the entire area. Rolling just specific sections would leave other parts unaddressed, which could limit the sod's establishment and lead to patchiness or uneven growth. Hence, rolling the whole area after watering is the recommended practice to ensure a healthy, well-integrated lawn.
