Iowa apple growers concerned about cold, snowy forecast

(Undated) -- The cold, snowy forecast could spell trouble for Iowa's apple growers. Joe Hannan, a fruit crops specialist with Iowa State University Extension says it's difficult to predict if the trees will be damaged at this point. He says growers will be watching the temperature, but also dewpoint, cloud cover, and humidity.

He notes many varieties are not blossoming yet, but could still be damaged depending on how cold it gets, and for how long.

Hannan says it would be especially difficult for apple growers who saw damage last year because of cold spring temperatures and then the August derecho, which caused extensive tree damage in a large part of Iowa.
