Overseeding is most commonly done by courses that use bermudagrass, which goes dormant during winter months. In the fall, a bermudagrass golf course overseeds with, for example, ryegrass seed on top of the bermudagrass. Then, as the bermudagrass is going dormant for the winter, the ryegrass grows in.

tight, dense green sward is a very competitive environment for young seedlings to successfully establish in. Creatingspace in the turf canopy is an important factor to consider, particularly if the long-term goal is one of species exchange.

Features - Real Science
Strategies to prepare bermudagrass fairways for overseeding in the Desert Southwest have changed dramatically over the past five years.
The simplest approach is often the best
It seems that at least 50 percent of the golf courses that overseed have a history of fair to poor bermudagrass recovery in the summer. It is these facilities where the simplest overseeding approach makes the most sense.
Burn-down herbicides make their mark
This idea has been around for many decades but has seen a resurgence of late. As recently as five or six years ago, it was common for golf facilities to spend more than $10,000 to haul away green waste, or organic debris, generated from aggressive fairway renovation prior to overseeding.
Sand topdressing replaces scalping and verticutting
This strategy does not involve any aggressive mechanical preparation or herbicide application but does provide the facility with a plan that will continue to improve overseeding, bermudagrass transition and golf course playability for many years to come.
