Do pistachio trees produce pistachios?
Only the female pistachio trees will produce pistachios. Pollination occurs with the wind. The wind carries the pollen from the male flowers to the female flowers. To maximize wind pollinating, you have to plant them strategically. Ideally, there should be one male tree for every 7 – 9 female trees, with the male in between the females.
Which pistachio tree is best for pollination?
In the United States, Kerman is the most popular female cultivar, which is pollinated most often by the male cultivar Randy. Pioneer Gold 1 and UCB-1 are hybrids rootstocks that are very popular due to resistance in Verticillium wilt. The natural pistachio tree pollination is made almost entirely by wind.
What is the difference between a male and female pistachio tree?
The male Pistachio trees are taller and robust compared to the female trees. Female Pistachios are apetalous i.e. they have no petals. The leaves of the Pistachio tree are compound leaves. The fruits of the Pistachio drops in heavy clusters that look like grape. Do pistachios need male and female to reproduce?
How do you collect pistachio pollen from a tree?
Pistachio pollen can be easily collected from male trees. Male inflorescences are collected by hand once the anthers have opened, and they are immediately spread on a special paper in a cool, dry place. Then they are shaken for the next 2-3 days.

What is the difference between a male and female pistachio tree?
The pistachio tree is dioecious (i.e. two houses”), meaning the male flowers are borne on one tree and the female flowers on another. Therefore, both male and female trees are required to produce nuts. The female flower is apetalous (no petals) and has no nectarines, thus does not attract bees.
Are pistachio trees self fertile?
Pistachio Trees don't self-pollinate, but we make it easy for you.
Do pistachios need pollinators?
Pistachios are wind pollinated. Although bees may be attracted to male flowers for pollen, they are not attracted to females since they lack pollen, nectar, and petals. Pollinizers (males) are often planted in the center of a 3 x 3 square of females, yielding an 8:1 ratio, or sometimes ratios up to 24:1 are used.
Do pistachio trees need bees to pollinate?
The natural pistachio tree pollination is made almost entirely by wind. Insects and bees do not help and rather deteriorate pistachio tree pollination. Pollen is transferred by wind from male trees to female trees. We have to place ideally 1 male tree in the center of every 7 female trees in small orchards.

How do pistachios reproduce?
It is only the female pistachio tree that bears fruit, and so many pistachio trees are now artificially pollinated so as not to waste space on unproductive male plants, however some countries still allow their pistachio trees to pollinate naturally by planting male trees in the vicinity of the female trees.
Do you need two almond trees to pollinate?

Pistachio trees have high water requirements especially during the filling of nuts (summer). However, farmers shall not supply very large quantities of water at few sessions in mature trees, because the tree vegetation can grow excessively and this can negatively affect the opening of the fruit.
Are pistachios easy to grow?
Growing pistachios is a long term process and requires patience. Pistachio trees only start to bear fruit when they're about eight years old, and a full harvest will only come fifteen years into the tree's life. If you have the patience, it's possible to grow your own pistachios. The trees thrive in hot, dry climates.
Why are pistachios so expensive?
According to The Cold Wire, pistachios are also expensive because of the costs associated with farming them. Apart from the obvious needs (such as enough water and fertile land in the right climate for the trees to grow) pistachios require a great amount of hands-on labor to harvest.
