The seasonal health of the greens depends on the depth and overall health of the roots. The plug on the right of the picture is a plug taken from our USGA spec nursery seeded with A-4 bent grass. The plug on the left is a plug from #4 green. The greens have the same fertility and fungicide program and the greens all receive the same amount of irrigation. St. Clair is a very difficult course to maintain due to the inconsistent subsurface composition, different turf varieties and the unreliable drainage and irrigation system.
From left to right, #4 green, #8 green and the nursery, these plugs represent the different generations of the newer greens. It is popular in the golf industry, to reconstruct subsurfaces and establish an A-4 bent grass surface due to the nature of the turf. We have made a little headway on renovating a greens surface to A-4. #5 was the first green we have resurfaced with A-4 and it should be a more playable and manageable green.
