Burt Tietje (T-J), owner of Tallgrass Farm about a mile north of Roanoke, tells the American Press the freezing temperatures merely slowed activity for a little while. Tietje said activity at the farm was slow before the cold weather arrived. He said the season typically picks up in February. Tietje says early signs point to a normal harvest.
