The main purpose of overseeding established turfgrass is to introduce new grass varieties. This practice is beneficial for several reasons. By overseeding, property managers can enhance the quality of the lawn by introducing improved grass varieties that may be more resistant to diseases, pests, or environmental stresses like drought or shade. Additionally, overseeding can help to fill in bare or thinning areas, leading to a denser, more robust turf. This not only improves the aesthetic appeal of the lawn but also its overall health and resilience.

In contrast, removing existing turf is not a function of overseeding; instead, overseeding relies on an existing turf layer to provide a foundation for the new seeds. Similarly, while overseeding can contribute indirectly to reducing soil erosion by creating a thicker turf, it is not its primary purpose. Lastly, overseeding does not aim to increase the height of the turf; rather, it focuses on improving density and health through the introduction of new genetic material. Overall, overseeding is a strategic practice to enhance the performance and appearance of established turfgrass.
