Pistachio

 Pistachios need long hot summers to ripen. The trees are slow growing, but eventually reachthe hieght of  about 20-25 feet. They are drought tolerant, need 800 chill hours, and require male and female for pollination.
Photo shows male and female planted this year. Because the chill hour requirement for pistachio is about  800 hours, I am not sure if it will fruit in our climate.
Pistachio can grow on any soil but need deep loamy soil for good fruit production.
Pistachio need long warm summer and cold winter to complete their dormancy need.
 
Plant Care
Irrigation
As with all my fruits trees, I irrigate them every 7-14 days during growing season .During winter months water every 4-6 week.

 
Fertilizer
We have 3-5 inch thick layer of partially compost mulch around the tree which provides all the nutrients needed for healthy ERE.
