[Arid_gardener] Citrus tree dying

[Linda Drew]

I agree with Dick that root rot is a possibility.
See this bulletin for information:
http://ag.arizona.edu/pubs/diseases/az1150.pdf

information on sooty canker, another possibility:

For a diagnosis, collect pencil-sized roots and send to the
Plant Pathology Lab:

>>I have a fruit cocktail citrus tree.  It's been in the ground for 7 or 8 
>>years.  It was a very healthy tree until one week ago.  A part of the tree 
>>just died.  When cutting off the dead part I noticed a black mold under 
>>the bark.  I trimed it back until there wasn't anymore mold.  Now another 
>>part of the tree is also dying.  I do not see the mold.  Is there anything 
>>that I can do?  Thank you for your help.  Jackie Katsoufis
