Cascalote tree losing leaves
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. -john |

Knock a branch over a sheet of white paper and check to see if any tiny insects can be seen crawling on it. (A quick Googling suggests that psyllid infestation is possible in April/May.) -- Pat in Plymouth MI "So, it was all a dream."

Did you ever get an answer or solution? John S. 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." -- David E.

I also recommend spraying with a general purpose pesticide once a week for two to three weeks. -- |

It is an idea to find out what you are dealing with before spraying. -- David - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Corporate propaganda is their protection against democracy |

I don't know what ' they' are even after considerable research.That's why I advised using a general purpose spray. We had the same problem on a cascolote tree where I work and by power hosing them they disappeared and the tree recuperated. The "bugs' showed up again this spring so I am repeating the power hosing treatment and spraying with an all purpose insecticide spray and it is definitely having an effect. -- |
