Some rainless days allowed the gravel in the Better Billy Bunkers dry out so now the spraying begins. Here on #2...
After spraying, the polymer dries and is checked for any areas of loose gravel which are marked with orange and resprayed.
Now ready for sand...
The bunker on #12 is filled with sand...
which is spread to a depth of 4-6".
On #4, stakes are used in the same way as the gravel. They are marked at 6" to help keep the sand at the same depth.
The same process on #17:
#17 with sand added:
The finished bunkers on #4:
And the finished bunker on #12. The life span of a Better Billy Bunker is a minimum of 10 years which should be 10 years of no washouts or flooding.
Matting is being added to the floors of the new bunkers on #5. The back bunker...
and one of the fairway bunkers:
A host of soil amendments are being added through the fertigation - Rx Fairway, Penecal, Turf Rx CA, Turf Rx Magnesium, Agri Rouse, and Potassium Carbonate.
The results on the ground are becoming more obvious. Greens are being cut, some for the second time. #4:
On Monday, the mowers will be lowered from .2" to .18". #1. After mowing, more top dressing, here on #1:
In order to train the Celebration to grow horizontally, the fairways are receiving a regular cut starting at .75"
Mowed fairway vs. not mowed:
The fairways are filling in. #1:
And #6. The deep green of the Celebration is striking.
Finally, some clever engineering. The sump on #10 needed to be drained during wet times so a small pump was seated in a bucket to prevent it from contamination by the soil. It's lowered into the cavity and operated as needed.
It appears to work fine. The water will be drained across the 11th fairway and into the marsh.
