They won't survive outdoors if their roots freeze. If the soil freezes
where you live, pistachio trees will almost certainly be killed.
BTW, you will need both male and female trees to produce nuts. It
several years for them to bear.
Buy a few trees and try them, but I wouldn't be too optimistic, unless
you've got someplace to bring them in for the winter.
