To give everyone a reference to today's green speeds. At the golf course I manage we have a Pro/Am in early March. The grass is just starting to green up from the winter and I am still cutting at my winter height (3/16"). All we do for the Pro/Am is cut the greens and the Pro and I determine whether to double cut or roll to increase speeds more. The irrigation system is OFF and will not turn on for another month or so. The winter has distributed the moisture levels in the soil very evenly and the grass is barely growing in March. At 3/16" HOC the greens are rolling over 10 feet and everyone is happy with the roll of the greens.
When the irrigation system is turned on to replace deficiencies of rain, the grass starts growing and the green speeds slow down dramatically. My typical green speeds during the summer months are 8 feet. The water comes on and the green speeds slow down.
The amount of water (and the type of grass) are THE determining factors in green speeds. To increase the speed of the greens, shut off the water and apply only enough to keep the grass alive not green. Back in Hogan's day, greens were cut at about 1/4" (but don't quote me on that). And yet the golf courses were drier overall compared to today. American golf must get away from high fertilizer treatments and heavy watering for the color green.
Focusing on the color green and demanding it, the superintendent is "forced" into overwaterng, over fertilizing, and cutting the turf too low. This is like living off McD hamburgers for every meal, taste great and your happy but your health is terrible. The hardest thing for a superintendent to do IMHO is to turn the water off.
