Why do we have to destroy the greens?

That is a great question. As a player, I don't enjoy this process any more than anyone else. I really wish we didn't have to do it. So why do we? Below I have taken several photos. Using a solid profiler, I can show you a cross section of the green. Notice the holes that are filled with the clean sand. These are a result of our aerification process. The sand creates a channel for air and water exchange and infiltration. As you can see from the photos, the root mass in these areas is much greater than the rest of the green. Strong healthy root zones are necessary for quality putting surfaces.
We are aerifying and filling holes on the red nine today. Plan on coming out to the course this week and enjoying some awesome fall weather.
Have a great day,
