AMES, Iowa (AP) — The cold snap may have taken a toll on some of Iowa’s fruit crops. Plant experts at Iowa State University say two nights of freezing temperatures damaged fruit blossoms at the Horticulture Research State near Gilbert. Superintendent Nick Howell says he’ doesn’t expect much of an apple crop, and there’s damage to the station’s vineyards and strawberries. Experts say the early spring sped up blooming, which is a sensitive stage for the plants. Fruit specialist Paul Domoto says it’s too early to tell the extent of the damage until growers can assess the conditions in their areas. He says site conditions and development stage will affect the outcome. Another freeze warning was posted into this (Thursday) morning, with temperatures in the 20s in northern and eastern Iowa.
