[Arid_gardener] Re: Citrus Leaf Yellowing and Dropping

[Olin Miller]

          Some leaf drop is normal for citrus particularly when new leaves 
are pushing out.

          Too much fertilizer-follow fertilizer instructions on the bag. 
Water before fertilizer and deep to after fertilizing.

          Too much or too little water..  Citrus needs a monthly deep 
watering in winter and twice monthly in summer.   Apply oiut to the edge of 
the canopy.  Test depth of penetration by inserting a slim steel rod. Should 
penetrate easily from 1 - 3 feet depending on the age and size of he tree.
