We have a pomegranate tree in our small, sheltered yard.  It is strong and healthy, presently covered in lush foliage and many blooms, as well as several already-forming fruits.  
Watering is on a communal bubbler system controlled by the condo i.e. we can't affect it, and waters deeply twice a week at present, increasing to three times a week in the very hot months.
I fertilized with  16-8-4P when the first buds started showing.
Last year we had an large crop BUT the fruits were dry and only pale pink inside, apart from one small fruit that was deep red and juicy.  What a disappointment!
What can we do this year to make sure that we get a delicious and nutritious crop?  All suggestions gratefully accepted
