It will be really interesting to see how they pull it off if they move it to the fall.
Augusta National’s primary turfgrass is bermuda. During the hot and humid Georgia summer, bermudagrass covers the landscape because of its heat tolerance characteristics (amongst other reasons). In the Fall as the nights become cooler, the bermudagrass goes dormant, stops growing, and turns brown. Once the weather patterns are desirable to grow cool season grasses, the bermudagrass is scalped down from tee to green to almost nothing. The scalping process can be quite aggressive depending on the bermuda’s health. It is very labor intensive and requires an incredible amount of resource inputs. Once the bermuda has been scalped, perennial ryegrass seed is laid out from wall-to-wall using calibrated spreaders that ensure all areas receive enough ryegrass seed to promote a dense and uniform turf canopy. In my personal experience in overseeding, we have used more than a million gallons of water per day to establish germination, matched with a fertilization program that can cost up to $10,000 per application in product alone (both statistics I have a hard time advocating, rationalizing, and standing behind). From the time the ryegrass seed is spread to the time you can re-open the golf course to play may be from 4-6 weeks depending on environmental and growth conditions.
