We are aerating greens today. We are using 1/4'' hollow tines. September is a huge golf month so we choose to aerate now so the greens will be table top smooth all September.
The 1/4" tines will have a minimal impact on the putting quality of our greens. They will be putting well the day of aeration. We incorporate the sand and roll the greens to provide a quality putting experience during this aeration process.
We are currently testing our greens with ISTRC http://www.istrc.com (International Sports Turf Research Center) to determine what our October aeration process will be. We will adjust our tine sizing and spacing to reflect the soil physical properties and the maturation of our new greens profile.
