    Yes. You will need a second tree. They are not self fertile. Here is an article for more information on pistachios: https://www.gardeningknowhow.com/edible/nut-trees/pistachios/growing-pistachio-nut-trees.htm

    They will grow... They may not thrive. Your area will meet the temperature requirements, but will be very moist compared to their native environment... Syria. You will need, both a male, and a female tree to produce fruit. You may get the tree to live, but you won't know it's sex for many years. Then you need another tree of the opposite sex to produce.

    A Mastic Tree does not have a root system considered invasive. I would however take into consideration it's size at maturity.
    Height of 10 to 15 feet and a width of 7 to 12 feet.

    You may want to give it a bit more room.

    Do you have functional male and female trees? Males must be available to provide the pollen for pollination.

    In some cases, pollination may occur, but because of weather conditions or nutrient issues, fertilization may not, resulting in shriveling of the ovule rather than fruit development. Pollination can stimulate fruit set, but then the nuts fail to fill.
    Nutrition can play a role; boron deficiency can be a factor in some areas.
    A soil test can help you determine if this is the issue.
    Weather temps can also effect nut growth.
    Drought stress can also effect nut growth.

    These trees will either be only male, or only female. I can't see a male branch, but I do see what looks like another tree growing right beside the tree. You may want to get rid of this before it takes from the health of your tree.

    Please include a close up photo of the male flowered branch.

    I too have this and I would say to leave it be. It's simple. I only have a female tree = not bearing edible fruit. A couple of years ago, I noted that I now had edible fruit but could not figure out how this happened. I assumed that there was a nearby male tree. Ends up, the male tree was growing out of the bottom of the trunk of my female tree. It is indeed a male tree, and is growing from the bottom of the trunk (not out of the ground, but the trunk). I've had edible fruit/nuts for years now. If it is damaging your tree, try cutting it back or you may have to remove it to save your female tree - if it is causing problems, since it is half way up the tree. You may try replanting a cutting from the male tree.

    Here's some info from the article on our website:

    "Harvesting pistachio trees is easy because Mother Nature does most of the work. Just spread a large tarp under the tree so the ripe nuts aren’t harmed by falling in the dirt. Pistachio orchardists use mechanical “shakers” to loosen the nuts, but you can dislodge them by rapping the branches with a sturdy pole or a rubber mallet. At this point, pistachio harvesting is simply a matter of gathering the dropped nuts. To maintain flavor and quality, remove the epicarp within 24 hours of harvest."

    You can read the entire article here: https://www.gardeningknowhow.com/edible/nut-trees/pistachios/how-to-harvest-pistachios.htm

    If you need more in-depth detail, we recommend talking with your local cooperative extension service.
