What Cause Whitish Spots on the Leaves of Star Jasmine?

Q. My star jasmine leaves are covered with a whitish
plaque. The leaves are turning yellow and falling off. I have noticed the green
leaves are only at the end of a branch and bare to the main stem. The plant is
approximately two years old and facing east on the side of a patio. What can be
done?
Star jasmine with whitish spots on the leaves.
A. I took a look at the picture and I saw the white spots
on the leaves but I could not determine what it was from the picture and your
description. I can only tell you about some general problems with star jasmine.
            First of
all, star jasmine will do very poorly in desert soils if the soil was not
amended with compost or a good soil amendment at the time of planting. Their
roots will not tolerate soils that drain water poorly as well. They do like
soils covered with organic mulch.
            They
tend to get root rot diseases in these types of soils and they will develop
yellow leaves along with leaf drop just like you are describing.
            However,
the white spots are a bit of a mystery. Star jasmine has milky sap in it stems
and if the stems are cut they will drip a milky sap on the leaves so watch for
that. If they were pruned recently they might have the milky sap dripping on
leaves.

            This
would probably be unrelated to the yellow leaves and leaf drop you are
mentioning. Bottom line, don’t plant star jasmine in our desert soils without
amending the soil a lot with compost or other suitable soil amendment. Consider
organic mulches on the soil surface.

  1. I have this, too- tiny white specks, and recently heard that hail can cause tiny holes in hosta. If there is milky sap in the jasmine, maybe hail (which we had) caused teeny tiny holes in it, which sent sap out? My plant is healthy, otherwise!
