Pomegranate fruit is dropping before maturity

Question

Have old 30+ year old tree I do not want to lose but lately (last 5 years or so) just produces and drops before the fruit is mature. Birds love it when they split though.

Was deep watered in August/September (by mistake this year by mother-in-law) for 12+ hours. I have not watered since. This has been a recurring problem in past years, however. I know as these trees get older they are not as productive. I want to enjoy this tree as long as possible as I feel it is part of our family now.

Answer 1

Over-watering and over-fertilization are the two main reason of pomegranate fruit drop. Hopefully, this will help: http://homeguides.sfgate.com/pomegranate-tree-hold-fruit-60108.html

One over-watering should not have caused serious fruit drop.
