The pistachio, a member of the cashew family, is a small tree originating from Central Asia and the Middle East. The tree produces seeds that are widely consumed as food. Pistacia vera often is confused with other species in the genus Pistacia that are also known as pistachio.
Plant it and then watch it grow. As long as the climate is right and you've got a male and a female, your Pistachio trees will produce a huge harvest every other year. And there's hardly any maintenance and upkeep to these dry-weather loving trees. Most trees produce around 20-25Kgs of nuts per year. That's plenty to share with your friends and family.

Since these trees are classified as fruit trees, pruning pistachio trees is integral to producing higher quality fruit while controlling growth. For young trees, select the three to five branches you wish to use as scaffold branches or the primary structure of your pistachio in April of the first growth season. Choose those that are equally spaced around the trunk but not across from each other with the lowest branch 24-32 inches above the soil and cut all other branches below this. Remove any upper branches that will shade the tree trunk and pinch those that are not scaffolds to 4-6 inches from the trunk. Then in June, prune the scaffold branches to 2-3 feet in length to promote side branching while leaving the lateral shoots to aid in shading the trunk as it grows. Maintain the open center structure as the tree grows taller by choosing secondary scaffold branches. You may prune two to three times a year with summer pruning occurring in the spring and summer and dormant pruning in the fall.
