Secondary producers were China, Turkey, and Syria. A 2020 report indicated that nearly half of the global production of pistachios in 2019 came from the United States, with production in Iran falling to as low as 7% due to US trade sanctions against Iran, climate change, and weak economic and water management in Iran.

Unique Growing Conditions
Pistachio growers are taking advantage of some unique growing conditions in the north, said UCCE Orchard Systems Advisor Katherine Jarvis-Shean. In areas of the Sacramento Valley where water and soils are high in boron, pistachio trees can thrive, unlike almond and walnut trees. This was a driver in the earlier pistachio plantings there, she said.
Infrastructure Issues
Reid Robinson with Sierra Gold Nursery predicted the northern production growing pains will be mainly due to lack of infrastructure.
Where are pistachios native to?

It takes five to seven years for a newly planted tree to produce a crop, but it takes 15 to 20 years for them to reach their full capability. Pistachios are pollinated by the wind, instead of by bees. Only one male tree is needed to pollinate 30 female trees.

Where do pistachios come from?

How do pistachios grow?
Pistachio is a desert plant and is highly tolerant of saline soil. It has been reported to grow well when irrigated with water having 3,000–4,000 ppm of soluble salts. Pistachio trees are fairly hardy in the right conditions and can survive temperatures ranging between −10 °C (14 °F) in winter and 48 °C (118 °F) in summer. They need a sunny position and well-drained soil. Pistachio trees do poorly in conditions of high humidity and are susceptible to root rot in winter if they get too much water and the soil is not sufficiently free-draining. Long, hot summers are required for proper ripening of the fruit.
Why do pistachios split?
Pistachio shells typically split naturally prior to harvest, with a hull covering the intact seeds. The hull protects the kernel from invasion by molds and insects, but this hull protection can be damaged in the orchard by poor orchard management practices, by birds, or after harvest, which makes it much easier for pistachios to be exposed to contamination. Some pistachios undergo so-called "early split", wherein both the hull and the shell split. Damage or early splits can lead to aflatoxin contamination. In some cases, a harvest may be treated to keep contamination below strict food safety thresholds; in other cases, an entire batch of pistachios must be destroyed because of aflatoxin contamination.
How long do pistachios live?
The pistachio tree is long-lived, possibly up to 300 years. The trees are planted in orchards, and take approximately seven to ten years to reach significant production. Production is alternate-bearing or biennial -bearing, meaning the harvest is heavier in alternate years. Peak production is reached around 20 years. Trees are usually pruned to size to make the harvest easier. One male tree produces enough pollen for eight to twelve drupe-bearing females. Harvesting in the United States and in Greece is often accomplished using equipment to shake the drupes off the tree. After hulling and drying, pistachios are sorted according to open-mouth and closed-mouth shells, then roasted or processed by special machines to produce pistachio kernels.
Why are pistachios dyed red?
Originally, dye was applied by importers to hide stains on the shells caused when the seeds were picked by hand. Most pistachios are now picked by machine and the shells remain unstained, making dyeing unnecessary except to meet ingrained consumer expectations.
What caused the pistachio industry to lose its harvest?

What diseases can pistachio trees get?
Pistachio trees are vulnerable to numerous diseases and infection by insects such as Leptoglossus clypealis. Among these is infection by the fungus Botryosphaeria, which causes panicle and shoot blight (symptoms include death of the flowers and young shoots), and can damage entire pistachio orchards. In 2004, the rapidly growing pistachio industry in California was threatened by panicle and shoot blight first discovered in 1984. In 2011, anthracnose fungus caused a sudden 50% loss in the Australian pistachio harvest. Several years of severe drought in Iran around 2008 to 2015 caused significant declines in production.
