As I said before, the pistachios is really an impressive tree. This tree is over 20 years old. Interestingly, the growing of the pistachios tree has a similarity with human being in terms of time and effort. Almost all pistachios trees begin to give crops approximately at age of 15. Planting the tree alone is not enough, they need to be cared closely throughout these years. So, you have to work and spend money for many years without harvesting anything in order to raise the pistachios. As I said, it looks like human being!
By the way, you can see some boughs belong to an olive tree in the left handside of the picture, of course this land is pretty fertile!
