There are two adjustments we are making to this Springs green's aerification to hopefully increase the speed of recovery. The two most important factors in recovery from hollow core aerification is the weather and the filling of the holes completely with sand. We can't control the weather, but we are trying to improve the filling of the holes made during aerification.
This photo was taken 2 years ago. Notice that there are approximately 5 holes that run from the bottom of the radio to the top of the antenna.
This photo was taken today. There are approximately 8 holes that run from the bottom of the radio to the top of antenna.
The difference is that the diameter of the holes in the photo taken today is smaller then two years ago. Thus less space is needed for the turf to fill in the holes. Yet, since there are more holes we are getting an equivalent effect of using the larger sized tines.
One other small adjustment we are making is to use a slightly finer sand. This sand is similar to our rootzone but should go into the holes easier since it is a smaller particle size.
With some good weather our goal is to have the greens filled in shortly!
