I have a 4 year old grafted Persian Walnut tree that up until last week was 
doing
great with no signs of problems.  We had a rough spring with several late 
freezes
back in late April/ early May, but since then the tree leafed out and seemed 
to be
doing fine.  The weather has been warmer in the last week, but not super hot. 
 It
has been relatively dry for the last two weeks.  The only thing I have done
differently this year was I did mulch all of my trees with grass clippings 
about 3
weeks ago.  All of a sudden the middle of last week, it looked like the tree 
was
wilting from top to bottom.  It progressed now to the point where all of the 
leaves
on the tree are brown and dead, but the new spring growth branches are still 
green
and otherwise mostly upright.   All of my other grafted Persian Walnuts, black
walnuts, butternuts, and hickories near by seem to be doing fine.  Just this 
one
tree.  Any ideas/suggestions??
