Which grass species is often used for overseeding dormant warm-season grasses?

Perennial ryegrass is often chosen for overseeding dormant warm-season grasses because it germinates quickly and establishes rapidly under cooler conditions, which are typical during the transitional seasons of fall and spring. This species provides a lush green cover during the dormant period of warm-season grasses like Bermudagrass, thereby enhancing the aesthetic appeal of the turf. Furthermore, perennial ryegrass has a fine texture that blends well with the coarser warm-season grasses, creating a seamless transition once the warm-season grasses begin to grow again in warmer weather. Its ability to thrive in cooler temperatures makes it particularly suitable for overseeding, allowing for effective erosion control and maintaining a vibrant turf appearance throughout the year.
