I live in the AZ desert and have a Cascalote tree [Caesalpinia
cacalaco] that my local nursery planted. It's approx. 8 feet tall x 8
feet wide. It was beautiful when it was planted four months ago, but
the tree is not doing well now. The leaves are turning yellow, and
leaves are falling off big time. I'm wondering if I might be over-
watering it (what are the symptoms of over-watering a tree???) Also,
some of the leaves seem to have little specks of a white crystalline
substance on them -- it kind of looks like rock salt. Is that a sign
of an insect problem? Thank you for any information.

I have the same problem with a Cascalote tree in our yard. It has the
same symptoms of dropping leaves and the little crystal specks on the
leaves. Did you ever get an answer or solution?

According to Sunset's "Western Garden Book", you are likely overwatering
it. This is a drought-tolerant tree that needs "well-drained soil and
infrequent, deep watering."
