I just happened to see this thread title on the homepage when I was looking for something else.
In Sept., we did a
Winter Solutions Roundtable webcast that is now available On Demand here:
http://www.gcsaa.tv/webinars/education/view.php?id=260 Michelle DaCosta, Ph.D., reviewed the physiology of the plant then Sam Bauer talked about steps you may want to take to prepare your course for winter.
Not sure if the specifics you are seeking are included but they did a great job, it is free for members, and you can earn ed points as well.
Best of luck - freeze will be here tomorrow!
