Chinese Pistache Leaves
The leaves on my Chinese Pistache tree are turning brown along the edges and then dying. This is happening at the ends of the brances, especially in the top of the canopy. Below are some photos of the leaves. From what I have learned, it is not the result of insect infestation or disease, but it has something to do with the soil, (Ie. too much water, not enough water, not enough nitrients, etc.), and may just be temporary. Has anyone else seen this happen to the leaves of a Chinese Pistache tree?
