Course Update for July 20, 2018

Progress Report on the 18th Green
The new 18th green continues to improve each week.

Here are a few of the key agronomic factors that we use as benchmarks before the green would open for play:

1) Canopy density (full coverage of the green surface with no gaps)
2) Minimum 6-inch root depth (bentgrass roots are vital for its survival and a minimum 6-inch root mass is required before it can handle stress from play)
3) 1/2-inch organic layer (approximately 1/2 inch of an organic based layer is required for the grass to be resilient to traffic and golf shots; this layer creates a protective buffer for the plant)

Here is where we stand today:

1) Canopy density has increased to the point where it is near full coverage but there are still some gaps.

2) Root depth has gone down to about 3-½ inches.

3) Organic layer has formed to about 1/8 of an inch. When you pick up the plug it doesn’t quite hold itself together. Once the organic layer has fully formed, it will.

Overall, we are very happy with how the 18th green is moving along and will continue to update on the progression as the green continues to mature.

Have a great weekend,
