My brother who lives in central Glendale (85301) has 2 dwarf navel orange trees 4-5 years old.  This year they had good crop production, the fruit were numberous and of a good size... Fruit looks fine and tastes good.  But they are dry rather than juicy. 
Any idea what could be causing this?

Thanks for any suggestions...
