I have a chinese Pistacho tree which we planted about 2 years ago that is not growing very quickly. We have to water our lawn (sod) quite a bit due to the dry climate in which we live(central valley of CA. near Modesto, CA.)

1. How can I tell if the tree is heathy and growing?
2. Should I be fertlizing this tree with something to
help it grow faster?
3. Any other care suggestions I should know that will help
with with this tree?
4. FYI this tree was 15gallon when we planted it. It is planted in our front yard and is in full sun.

Thanks for you help= Trey

Chinese Pistache is a slow growing tree by nature and trying to rush the process with lots of fertilizer will only result in weak, disease-prone growth. It isn't unusual for some trees and shrubs to take a year to become established after being planted. It's spending its energy developing a supportive root system during this time. By the second year you should begin to see some top growth. As a slow-growing tree you may only see 6" of growth per year. As long as the foliage is a healthy color and you see new buds swelling each spring, your tree is probably healthy. Pistache will adapt to all kinds of growing conditions, including poor soil and very little to lots of water. I think your tree is doing what comes naturally - growing at its own pace. Eventually it will reach 30'-60 in height and produce brilliant fall color. Enjoy your tree!
