Growing & Harvesting

Growing American Pistachios

The pistachio tree (pistacia vera) originated in western Asia and Asia Minor, made its way into Mediterranean Europe and now thrives in the dry climates of the American west. Advanced production technologies, efficient harvesting and sophisticated growing techniques now make the United States #1 in global commercial production.


Harvest takes place anywhere from late August to early October. Between 5 and 7 years of age, the pistachio tree begins bearing fruit (yes, it’s a drupal). A biennial bearer (a heavy crop one year and little crop the next), there appears to be no upper age limit to a tree’s viability. Once ripened, the nuts are quickly harvested, cleaned, sorted and roasted for the perfect snack or for ingredient usage.


Nature decides when it’s time to harvest pistachios. In the American West, harvest occurs in September or October when the fruit is mature and the shell has split. For American Pistachio Growers, the year’s work culminates in the highly coordinated effort between our member growers and processors to harvest and deliver the crop quickly and efficiently. This process ensures the highest quality pistachios year after year, as shown in this video.
