What is the primary purpose of sod installation?

1. The process of preparing soil for planting

2. The method of applying fertilizers to promote growth

3. The process of laying pre-grown grass to establish a lawn quickly

4. The technique of seeding directly into the ground

The correct answer is: The process of laying pre-grown grass to establish a lawn quickly

The primary purpose of sod installation is to lay pre-grown grass to establish a lawn quickly. This method allows for immediate coverage and instant results in creating a green, lush lawn. Unlike seeding, which requires time for the grass to germinate and grow from seed, sod provides an established root system, which reduces the waiting period and immediately enhances the appearance of the landscape. Sod installation is particularly beneficial for areas that need to be usable right away or for situations where erosion control is necessary, as the mature grass helps to hold the soil in place effectively. This approach not only facilitates rapid lawn establishment but also allows gardeners to benefit from a dramatic transformation of the landscape in a short time frame, making it a preferred choice for many homeowners and landscapers.
