My Chinese Pistache tree has brown tipped leaves. What is the solution?
It is hard to diagnose this without seeing the tree or at least a picture of the tree. In our opinion, there could be various reasons for the brown tipped leaves.
If it is a newly planted tree, the answer could be that it has gotten too dry; even an established tree can suffer in dry times. Over fertilization, weed killers or a chemical spill (even a small one) can also cause the brown tipped leaves.
This is a quality tree and worth trying to save it, if possible.

For any of the above problems, my best recommendation is to replace any grass with mulch under the tree and water it well during the dry spell.
