[Arid_gardener] Question from Home-Hort WWW page

[paul christensen]

I was wondering why my 2 ruby red grapefruit trees' leaves are turning
yellow?  They were planted in the spring of '06 and then suffered through
the harsh frost of last winter.  I covered them up and thought they had
survived ok.  The leaves grew back and were nice and green.  Now with the AZ
temps over 110 degrees I am deep watering once a week in addition to the
automatic shorter waterings from a drip system 3X a week.  Am I over
watering?  I have not fertilized them.  The leaves have recently turned
yellow.  Please advise what I need to do -or not do.  Thanks for your
information and help.
