Because my area in northeast Florida is becoming more drought prone every year, I am considering cultivating more pomegranates on my large property. In my blog below, I have a picture of a Russian variety from about one year ago. I have since planted it in the ground and it has grown to about 5'. It did have a lot of flowers, but none set fruit. Anyhow, I was wanting to know how important or helpful it is to have a companion plant(s) of a different cultivar to help in fruit set.
