Growing to a height of 40 feet and width of 30 feet, the Chinese pistache is an excellent shade tree for smaller buildings. At maturity, its canopy is umbrella-shaped, with a pleasing symmetry. It is a moderately fast grower, but whether planted from bare-root or container, will need several years before reaching the best appearance. Its fine textured foliage is a medium green throughout the growing season, turning to flame red, orange and yellow in the fall. Small white flowers appear in spring, and on the female tree, can develop into red berries.
When picking a Chinese pistache at the nursery, look for a tree 6 to 8 feet tall, with a trunk diameter of 1.5 inches. A young tree in a 5-gallon container is a good size for a home gardener, or you can purchase the tree as a bare-root specimen. Fall planting is best. Plant the pistache in full sun, with fertile, well-draining soil. Water every three to four days for the first three weeks after planting, then cut back to twice per week. Mulch after planting to maintain moisture. Once established, the pistache is quite drought resistant.
The Chinese pistache is generally a very hardy, easy-care tree. AgriLife calls it one of the most beautiful, pest free and easily maintained shade trees for the southwest and gulf coast regions. Water deeply at least every two weeks during the summer, once a month in the winter. Fertilize in the spring and fall for optimum growth and health. Shaping and pruning as the tree develops will lead to the best canopy appearance.
According to the Arbor Day Foundation, the Chinese pistache has been described as an "ugly duckling", because it grows from an unattractive young tree into a magnificent specimen tree at maturity. It is used as the rootstock for commercially grown pistachio trees. The Chinese pistache has male and female trees, with only the female developing berries. It is the first shade tree to receive the "Earth-Kind" designation from the Texas Agricultural Extension Service for its high resistance to disease and pests.
