Keith Edwards on Instagram: "If you have lots of low temperatures and even frosts in Winter, then the complete opposite in Summer, with long hot and dry days, then these are the perfect nut trees for you. Pistachios require a male pollinator and one will be fine with about six female trees. A great looking tree and, once they get going, they are highly productive. This is Pistacia Vera not the commonly sold Pistacia chinensis which is decorative."
