Chilling Hours

It's COLD. But our trees love it---why???

In order to bear fruit in a growing season, pistachio trees require a minimum of 400 hours of weather 42f degrees or cooler. This triggers the trees to become dormant which "resets" their annual growing cycle. When weather and climate do not provide sufficient Chilling Hours, instead of bearing fruit, pistachio trees exemplify vegetative energy. Based on the weather experienced thus far since harvest, ARO Pistachios, Inc. anticipates a forthcoming bountiful growing season!
