Pistachio Tree

Pistachio is a deciduous nut tree grown for its edible kernels and long, hot-season growing needs. Its grayish compound leaves and rounded, spreading crown give it a distinct presence in a sunny orchard or suitable garden. ## Growing Conditions Choose full sun and deep, well-drained soil in a hot, dry-summer climate; the species has high salt tolerance, though local soil and water conditions still matter; this species is cold-intolerant, and local performance varies with climate and selection. Choose a site with long, hot summers and mild winters; hardiness varies by climate and selection. See [Utah State University’s pistachio profile](https://extension.usu.edu/treebrowser/catalog/pistachio) and [PFAF’s Pistacia vera profile](https://pfaf.org/user/Plant.aspx?LatinName=Pistacia+vera) for cultivation and hardiness context. ## Garden Use Grow it as a nut crop: male and female flowers occur on separate plants, so fruit production requires compatible trees. The inconspicuous brownish-green flowers appear in early summer, and the leaves and fruit color in fall. ## Maintenance Give young trees water while establishing, then avoid prolonged wet soil. Provide room for a mature tree and plan for harvest and cleanup of fallen fruit.
