Clubhouse Green regrass update

As many of you know, the Clubhouse putting green is scheduled for a minor rebuild this summer.  The reason for the needed repair is due to the incorrect initial construction.  When building a green, regardless of surface elevation changes, the soil profile is to remain the same.  This means there should a consistent 12-14 inches of green's mix regardless of contours.  In the picture below you can see the different amounts of sand in the profile of the green in the middle core (taken from the hump in the middle of the green) from the core on the right (taken on the #1 tee side).  The core on the left was taken from the chipping green on the front right hump, it's the worst by far.  The tiles on the floor are 18 inches wide and you can see the amount of mix in the cores is way too much.  Uniformity is key within a green's profile to maximize water uniformity.

The process to repair the Clubhouse green is pretty simple.  The golf maintenance staff will use a sod cutter to strip off the existing grass.  Once all of the existing grass is removed, stakes will be marked with a line about 4 inches from the bottom and another at 12 and 14 inches above the bottom line.  The stakes will be installed into the drainage layer of the green up to the bottom line.  Once all of the stakes have been installed and a grid has been laid out on the green, it will be time to remove the excess soil using the top two lines on the stakes as a guide to keep within parameters.  Once the entire green is within the acceptable soil depth range we will float the green out to smooth all the surface cuts, fumigate and grass.

Due to all of the rain that has been pounding the State as of late, the fumigation company is way behind schedule and can't fit in my small 5000 square foot project.  Therefore, it looks like the putting green project will be getting underway the first part of July and fumigation will take place during the week we are closed to aerify the course.  This actually works out better.  Once the green has been fumigated, grassing will take place directly afterwards and the grow-in should take about 8-10 weeks.
