I can understand OG winter killing, but tall fescue, if the KY31 type, I don;t understand winter kill. I don;t doubt that you had a problem with it but I just don;t understand what would cause it. Granted we don;t have prolonged winters (although some years they seem like it, but I've not seen any other grass that can be grazed down to almost bare dirt and come back with a little warm weather and rain. The stand would be weaker, I see that all around me, but it wouldn't die.
- We usually rest "improved" pastures from late August till a killing frost, before grazing the stock pile. Not grazing in the fall may have helped a little by moderating temperature.
- It is well known that alfalfa will not persist w/o great fertility. We have been grid testing and building up P and K.
- Barnenburg is the biggest seed supplier. No K31 here. Other than that I am sure they sell the same improved seed in Missouri, Iowa, and Minnesota. I don't think they have factered in what it takes to survive an open winter at -30 F.
- I found some Wisconsin hardiness data by variety. Fescues and OGs were 2s and 3s. Native grasses were 1s (best) and 2s... Looks like you need to be #1 when the site is exposed, dry, and cold.
