Fore the Golfer How Does Summer Heat Stress Affect My Game? R egardless of the weather, superintendents frequently are asked to push putting green turf to its limit to meet player expectations. Superintendents face a real dilemma during hot summer weather: continue pushing for fast green speeds and risk turf damage, or err on the side of safety by raising mowing heights and risk complaints about slower green speeds. Superintendents walk a fine line between these choices in an effort to provide quality summer playing conditions. However, when conditions dictate, they must be 22 | CSGA Links // July, 2017 prepared to make adjustments that protect long- term health and playability of the putting greens. One adjustment superintendents make to protect the putting greens during hot weather is raising the mowing height. Mowing at low heights is a common practice to achieve fast green speeds. Unfortunately, low mowing heights also leave very little leaf area available for photosynthesis. During periods of hot weather, turfgrass that is mown extremely low will struggle to produce enough energy and can quickly decline. www.csgalinks.org
