Minnesota Apples Survive Cold Temperatures Apple growers dodged a bullet, got lucky, caught a break, however you want to phrase it, but the really cold temperatures earlier this week did not damage the apple blossoms. When I got to the studio a little before 4:30 my computer said the temperature was 27 degrees. I think the readings are taken from the Faribault airport. My cell phone said the temperature was 28 degrees. A frost would not have damaged the apple trees, but if it would have killed the apple blossoms the trees would not produced any apples this year. David Bedford PhD. who is an apple breeder at the University of Minnesota Landscape Arboretum told me he was not aware of any significant damage from the low temperatures. He said he has seen apple blossoms survive temperatures of 28 degrees. Then another time you may see damage at temperatures just above freezing.
