Q.
Can you tell what is happening to my mock orange shrub? They are 3 to 4
years old and getting enough water. They were planted in topsoil used in other
locations with good results. They are the fourth different plant I tried to
grow in this area without good results. The
leaves are turning brown starting at the tips.

A.
From your picture the leaves scorching like that could be not enough water
applied or not applied frequently enough or even too frequently; high intensity
sunlight and intense heat from surfaces radiating heat back to the plant; using
a poor soil amendment at planting; lack of fertilizer or a lack of an iron
fertilizer because the leaves are yellowing.

These
problems can be working alone or in combination with each other. If just one of
these problems is present, it can affect the overall ability of the plant to
combat extreme desert conditions such as high temperatures, low humidity and
poor soils.

is not a desert plant to begin with so we have to put more resources into
keeping it look good. It’s one of those plants that does well if it is in the
right location with the right type of soil amendments and irrigation.

Address
the potential water issue first. I would flood the areas with a hose once a
week in addition to your normal waterings. Make sure you are not watering daily
but every 2 or 3 days right now.

Add
good quality compost to the area. This can be on top of any mulch you have and
water it in. Fertilize
with a good quality fertilizer such as Peters, Miracle Gro or Osmocote. Add
soil iron in the form of iron chelate, use only EDDHA iron chelate if applying
it to the soil.

Water
thoroughly giving the plant roots a chance to breathe and the soil to drain
between flooding. Look for improvement to the plant the following spring
(February to May). It is too late in the season now to see much improvement in
growth.
