Pistachios are of Mediterranean and Middle Eastern origin. Your tree needs a hot and dry climate, semi-desert, with hot summers so that the fruit can ripen properly. It tolerates up to 40 degrees Celsius. It resists the wind well, but not the rain.
The tree takes more than 5 years to bear fruit and does not reach its maximum production after 10 or 15 years. It produces fruit for 60 years.
Simply move the tree so that those fruits that have reached their point of maturity and are ready to be harvested can easily be released. You know that the fruit has reached this point because you can see that the shell of the fruit has opened and you can see the deep green inside. It is usually harvested before it is fully ripe to avoid pests that could damage the fruit.
Once collected, the cascade layer must be removed to prevent the proliferation and development of fungi that generate toxins. It is important to emphasize that if the pistachio shell is not open, this fruit should not be eaten, since it is still green and unripe.
