What does "renovation" refer to in turfgrass management?

In turfgrass management, "renovation" commonly refers to the process of killing existing turf and replacing it with a better type. This approach is often necessary when the current grass type is unhealthy, unsuitable for the area, or unable to thrive due to environmental conditions. The renovation process typically involves the complete removal of the old turf, which may include methods such as herbicide application or physical removal, followed by the establishment of a new grass species that is more appropriate for the specific conditions of the site, including soil type, climate, and intended use of the turf area.

By choosing a more resilient or compatible species, turfgrass managers aim to enhance the overall performance and aesthetic of the lawn or field. This process is particularly significant in cases where simple improvement or maintenance of existing grass would not suffice due to deep-root diseases, invasive weed presence, or poor grass variety.
