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.

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 h
ospitable place. We can, as all animals can, because we have legs.
For this reason, it’s location, where it’s planted, is extremely important.

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.
