Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Non-native Chinese Pistache tree with dead branches in Georgetown TX
Answered by: Barbara Medford

QUESTION:

Have mature Chinese Pistachio tree with many dead branches and few buds forming so far this spring - has been beautiful for many years. Do you know why this is happening and what can be done about it? Thank you

ANSWER:

Pistacia chinense is native to China, Taiwan and the Philippines, and therefore out of our range of expertise.  The Lady Bird Johnson Wildflower Center is committed to the care and propagation of plants native not only to North America but to the area in which they are being grown. Here is a website from the USDA Forest Service which might give you some information you need. 

However, while we have your attention, may we give you a couple of reasons why we would be happy if you replaced your tree with something native? First, read this Texas Invasives.org Plant Detail Page on Pistacia chinense. Then, check out Dave's Garden Forum on Chinese Pistache. There are two very negative opinions about the tree, one from Texas.

We suggest you contact the Texas A&M AgriLife County Extension Office for Williamson County. They should be able to help you with the diagnosis and treatment of the tree's problems.
