Want to plant a Chinese Pistache in clay soil. I also live in the desert. What reccomendations would you have in regards to amending the soil and how to go about doing it? Also, can my tree survive here? The zone seems to say it will. Also, how can I ensure that the pistache I buy will be of the red variety come fall?

The tree is hardy in Zones 6-9 and takes full sun. As long as you fulfill its growing requirements, the tree should thrive in your area, though it may need additional watering during times of extreme heat and drought-like conditions. If you want berries, you'll have to plant both male and female types. However, if you're simply looking for red fall color (without the berries), then 'Keith Davey' is a male variety of Chinese pistache that has reliable bright red fall color. Also, keep in mind that Chinese pistache trees grown from seed vary from yellow to red to purple, and half of the seedlings are female. Reputable suppliers should label their plants.
