Below is a photo of the 17th green last spring, on May 3rd, following two days of rain totaling 1.79". Notice the two birdbaths. This was a common occurrence. Any idea where our weaker turf was on this green or where winter kill usually occurred?
Now look at the 17th green following a 1" rain today after we had XGD drainage and some surface re-contouring to remove the birdbaths. Quite a difference. Over the years, 17 has been one of the most difficult greens to manage. I'm quite certain now that we have internal drainage we will see a dramatic improvement to the overall health and condition of the turf on this green.
