What is the term for grass strips laid down for lawn renovation?

The correct term for grass strips laid down for lawn renovation is sod. Sod consists of grass and the part of the soil beneath it that is held together by the roots. It is an effective way to establish a lawn quickly, as it provides an instant cover of healthy grass. When installed correctly, sod helps prevent erosion, suppress weeds, and creates an immediate green space.

In contrast, grass seed refers to the small seeds that germinate into grass plants, which takes time to grow and establish. Topsoil is the upper layer of soil that may be used in conjunction with grass seed or sod but does not refer specifically to grass covering. Lawn mix typically refers to a combination of seeds or fertilizers designed for lawn use, rather than pre-grown grass strips. This distinction highlights why sod is the most appropriate choice for the question.
