Because the greens are predominantly Poa annua, which is much more susceptible to ice damage, there appears to be a considerable amount of damage to about 50% of them. We will know more as the weather warms up and the covers come off, but samples that were taken from questionable areas are not showing signs of life after two weeks in the window.
Large areas on the front of #7 green and up the middle of number six green that hold water appear to be dead. The plugs in the picture above have been transplanted and watered in dishes in a window sill in the grounds maintenance facility.
On number two green samples were taken from the front, which was covered in ice, and the back, which was not. It is evident that the turf under the ice is not in good shape despite the fact that the ice was removed.
The trial putting green, although immature, appears to have made it through the winter in excellent shape as would be expected with bentgrass.
