( 2011_03_22 - #12 Green )
Yesterday Brandon and I went for a walk to see how the water was moving and the ice was melting. There were quite a few greens where we could see a lot of turf and the above picture of #12 green is a good example of what we were seeing. However there were a couple that showed some signs of poa annua death in a very sporadic pattern, greens #16 and #7.

Some of the turf loss is obviously caused by where the water was sitting in the low pockets, the back and center of #16 and the back and front of #7. Weak Annual Bluegrass, freeze/thaw of water, perhaps smothering under ice cover for the entire winter; These are all possibilities of why we lost turf in these areas. I will say it is a bit early to declare the spots completely lost though. When things start to dry and warm we will be able to better determine if there are any living plants in these spots and take the actions we need to take to get the turf back.
It is amazing what changes in 12 hours though. Today we are looking at a blanket of 3-5" of heavy wet snow covering the entire golf course. So when it starts melting off we will be back out making sure the ice is getting broken up and water is moving off the green surfaces. And other then the few spots of potential turf loss, the turf looks pretty good coming out of winter. It appears the snow mold chemicals we used for protection over the winter have worked, and the vole damage is much less then anticipated. Let's hope this is the last blast and spring is right around the corner.
