Last One of the Year

Monday and Tuesday we performed a solid tine aeration to the greens. This was our last aerification of the year and an important one going into winter. The following is a detailed sequence of events that we use to accomplish our goal of aerification to the putting greens all while minimizing the disruption to play.

Step 1: The greens are verticut in two directions.This vertical mowing results in shallow lines into the turf canopy where grass and thatch has been cut and removed leaving space for sand to settle into.

Step 2: Greens are sanded then aerified with a 1/4" solid tine tine to a depth of 9". The machine used is called a vertidrain and one of it's many benefits is the "kick adjustment". This allows us to adjust the tines to kick while they are below the surface of the green resulting in fracturing of the soil and a break up of the hard pan layer that naturally develops after a typical core aeration program. The point here is, while the result to the surface is a small 1/4" hole, the process is very aggressive under ground opening up new pore space for water, air and roots.

Step 3: Once the sand is dry on the surface, the green is rolled taking out many of the imperfections and working the sand into the turf canopy. We then brush the green with a mechanical drag brush and roll again. 

The finished result was a smooth but sandy surface and all in all, a very succesful aeration. Thanks and we'll see you on the course.
