Q. I have two tree form privets; one has nearly died, and the second looks to be withering at the top.  I have 8 bush form pivots that seem relatively healthy, and 2 that have completely died with one trying to bounce back from near death.  All the trees and bushes are in the same area getting the same amount of water. There just doesn’t seem to be a reason why some die and others thrive right next to each other.  Japanese privet dieback. Jp is a mesic plant not suitable for rock, dry or very hot locations. A. First of all, Japanese privet, like its name suggests, is not suitable for the desert. It’s suitable for Japan and similar climates. Whenever we take a plant and grow it outside of its “comfort zone” (parts of Japan and China) we will have problems unless we take these problem areas into consideration. Plants, unlike animals, cannot move from an inhospitable place to a more hospitable place. We can, as all animals can, because we have legs. For this reason, it’s location, where it’s planted, is extremely important. Japanese privet can handle the hot temperatures of southern Nevada but not dry locations. It does very well in lawns in Las Vegas.            Do You Know What Will Happen Tomorrow? You are looking at this plant at one point in time. You don’t know what will happen to this plant in the future; all you can do is look at its current situation and what happened to it in the past.             Japanese privet will do okay in the desert if it receives afternoon shade, enough water and soil improvement; just like Japan. Japanese privet is what we call a “mesic” plant and must receive adequate amounts water on a regular basis. Secondly, Japanese privet performs well with amended soil and needs this soil improved on a regular basis to survive. For this reason, it doesn’t like to be surrounded by rock mulch when the amendments run out. Thirdly, it doesn’t like direct desert sunlight all day long. Particularly if surrounded by rock.
