The answer to 'how does sod work' is that sod is pre-grown grass that is cut into rolls or pieces and then installed on a prepared soil surface. Sod provides an instant, mature lawn that can establish quickly and give your yard an instant green, lush appearance. To install sod, you first need to prepare the soil by removing any existing grass or weeds, tilling the soil, and leveling the surface. Then the sod pieces are carefully laid in a staggered pattern, similar to laying bricks, and the seams are pressed together tightly. Finally, the sod is watered thoroughly to help it take root in the new soil.
Sod is a popular choice for homeowners who want an instant lawn, as it can be installed at any time of year and will typically establish within 2-4 weeks. However, sod does require regular watering and maintenance in the first few weeks to ensure the roots take hold in the new environment.
