Pistachio tree has fruit but no nut!

mikeinsantarosaJune 19, 2013

I just discovered that my neighbor has 2 healthy looking Pistachio trees and there are bunches of nuts in the limbs. I picked a nut and there is nothing inside. He said I could harvest them but I think maybe something's wrong with the tree because of the missing fruit. Both trees have nuts and both trees, the nuts are empty. What's the problem here?

They didn't got pollinated--they need a male pistachio tree for pollination.

Thanks for that. How do you tell the difference between make & female trees?

Based on your description, your neighbor's trees are females.

Female trees have three to five leaf-clusters per leaf-stem, whereas, male trees only have one leaf per-leaf stem; female trees are the only ones that bear fruit...males produce pollen, not fruit.

thanks for the help - you're right there is no male in the area.
