As mentioned in the previous post involving ice damage, the greens will require constant monitoring. Once the ice on the green is exposed several samples of turf and soil are pulled from that green. Measuring ice depth is important and I will also use an infrared thermometer to document ice and soil temperatures. Smelling the samples for a foul odor is also important because it can indicate decomposing tissue or anoxic conditions. The plugs are then brought inside to monitor growth. I also look at the moisture as the samples thaw, if there is green moisture that can indicate possible cellular damage. As indicated for annual bluegrass the range is typically 45-90 days it can survive under ice. More samples will be taken throughout this range. Here is a picture of one sample pulled at 44 days under ice.
After looking at and smelling this sample there doesn't appear to be any issues, but it will be left inside for several days to make sure.
