I have had a lot of questions about the collars this year. We installed Penn Trio bentgrass on most of the collars last fall. We were not able to aerify it early this spring because the sod had not rooted yet, we had to wait. The original schedule was to aerify collars on May 21st. This was pushed back to the 28th due to weather and moving of opening day. We have completed the aerification on the course except for 2 greens. They will be completed today.
After assessing all of the bentgrass on the course, it seems to me that they are just young and compacted. Their root system is not deep enough. This is why we will be aerifying and top dressing the collars on a monthly basis. We need to relieve as much compaction as we can that resulted from the construction. We will continue to monitor the situation and make necessary changes when needed. Thank you.
