Pistachio is a slow-growing tree, taking 5 to 6 years to produce the first crop of nuts. The first harvest produces about 2.3kg. Pistachio is alternate bearing meaning that the tree can produce one year a  heavy crop, followed with a lighter crop the next year. Good irrigation and good pruning practices can reduce alternate bearing, but not avoid it completely. Male and female flowers are born on separate trees; a female tree planted alone will not produce nuts unless the male tree is growing nearby. For best pollination, plant a male upwind of every 10 to 15 female trees. They are currently being cultivated in large scale in the orchards in the USA, Iran, Greece, Syria and Turkey.
