Q. I have two ‘Red Push’ Chinese pistache trees planted about three years ago and doing well. Recently one was shocked and I’m not sure what happened. This occurred almost overnight. I gave it a few extra gallons and added two drippers to each plant. I don’t use any Round up or anything like that. Can it be saved?
‘Red Push’ Chinese pistache are damaged with high winds |
A. It will take a while, but the tree should be fine. The tree will use its stored energy to put on new leaves and replace the dead ones. In the future it’s important to note the weather occurring during that time because we did have some strong winds a few times this summer.
Strong Winds are Damaging and Trees Use More Water
Strong winds are particularly damaging in the spring when leaves are new and tender.
Strong winds equals increased water lost by plants. Sudden death of leaves right after strong winds signals a need for water. But that water application is usually just once.

However, frequent watering coupled with poor drainage might also cause this problem. My guess is that leaf death was coupled with the wind. So be careful with applying water to landscapes. It can be the “giver of life” in the desert, but it also can be the “giver of death”.
Established Trees Have Stored Food
A three-year-old tree like ‘Red Push’ has stored “food” in its branches that it relies on when pushing new leaves. It takes a bit longer for the tree to respond during the spring and early summer months because it has “used up” all its “spring” buds putting on new growth. It’s like a double whammy. It may take the tree a bit longer to produce new buds and new growth.
Chinese Pistache is Mesic not Xeric
Tree response to leaf death occurring in late summer and fall is much more rapid since the buds are already formed and new growth happens much faster.
Remember that any of the Chinese pistache trees are mesic in their water use; they can tolerate desert soils but need a little bit of irrigation help. They grow best when surrounded by other plants that require water. As with most mesic trees, they can tolerate lawns when there is decent drainage.

are there any difficulties during planting this crop?
It is not planted as an agricultural crop but a landscape tree. There are no problems using any of the Chinese pistache for landscaping.
