What is the established method that involves laying down pre-grown grass sections?

Sodding is the method that involves laying down pre-grown grass sections, known as sod. This technique is used to quickly establish a grass cover, providing an instant, mature lawn or turf area. Sods are composed of strips of grass and soil that have been grown in a nursery; when these sections are placed on the ground at the desired location, they can effectively root into the existing soil, leading to rapid establishment and a green landscape.

This approach is particularly beneficial for areas that require immediate coverage, such as newly installed landscapes, sports fields, and erosion-prone areas where rapid vegetation is essential. Sodding also helps prevent soil erosion and offers a solution for immediate aesthetic appeal.

In contrast, methods like plugging involve planting small sections of grass, which takes longer to fill in, while sprigging is the process of planting small pieces of grass stems or roots, which also requires time for establishment. Seeding involves spreading grass seeds on prepared soil, which can take even longer to germinate and establish compared to laying sod.
