The following video describes how and why turfgrass on golf courses can die in the summer? Keep in mind that the level at which a golf course green or fairway is maintained is significantly different than the basic and simple work that is utilized to take care of a home lawn.
For example, a bentgrass golf green may be mowed at a height of .090 one thousands of an inch. Consider that bentgrass grows to a height of 10 to 12 inches in in natural state. When you put the intense pressure of shaving the turf down to almost nothing, starving it to achieve faster putting speeds, mowing it everyday, exposing it to golfer's foot traffic, ball marks, limiting water, rolling the green with heavy rollers for speed and intense weather conditions then you can see how both greens and fairway turf is under constant stress and pressure to survive.
