why isn't my pomegranate tree making fruit? (growing, trees, spring)

[love roses]

I've had this thing for 2-3 years now. It's growing and it blooms every spring but that's all it does. I know the tag on it said it was a fruiting one, not ornamental, unless the nursery mistagged it or something.

[wit-nit]

Many trees that are ornamental are marked fruiting or semi fruiting. With that being said, if yours is a fruiting type, are you watering thoroughly (deep) enough and often enough to keep it slightly moist, have normal ph type soil mixture, feeding it on a schedule, full or part sun.
There are also ornamental pomegranate shrubs. What does the tag say about the species (name of plant botanical).

Here's a good article on pomegranate growing;http://www.freshplaza.com/news_detail.asp?id=15337
