What is a main reason to select annual ryegrass for overseeding?

Selecting annual ryegrass for overseeding primarily revolves around its ability to establish rapidly and provide a green cover during the dormant season of warm-season grasses, like Bermuda. When Bermuda grass enters dormancy, it turns brown, and annual ryegrass can fill this visual void by remaining green, thus enhancing the aesthetic appeal of the golf course. This rapid establishment is crucial as it allows for quicker recovery and coverage, ensuring that the course remains visually appealing and playable.

The quick growth rate of annual ryegrass allows it to germinate and establish a dense turf in a relatively short period, making it an ideal choice for overseeding during the transition from warm to cool seasons. This contributes not only to the appearance of the greens but can also aid in preventing soil erosion and reducing weed competition.
