The summer was harsh, but now the weather is cool, rainfall is adequate and the ground is soft. It's time to get out the spreader and fill in some of those bare spots. Indeed, fall is the best time to plant cool season turf like fescue and ryegrass, but you'll probably want to wait till spring before sodding or seeding warm season turf like bermuda, centipede or zoysia.
Lets start with warm season grasses which are usually sodded.
However, successful transplanting of bermudagrass is highly dependent on having a healthy sod, which is hard to determine when sod is dormant. In addition, off-season sodding of Emerald zoysiagrass and centipedegrass in and north of Athens may result in more winter injury than the other zoysiagrasses and hybrid bermudagrass. Even with the more cold tolerant warm season turfs, you probably don't want to lay sod in the off-season without a written guarantee from a reputable supplier. However, as springtime approaches management becomes critical. If overseeded ryegrass is not managed correctly during spring green-up, moisture, sunlight and nutrient competition can severely damage warm season turf.
