How much rain do you get annually? Depending you may need to offer supplemental irrigation to get good fruit crop. Elders like lots of water as a general rule, but some varieties, at least here on the west coast and the ones that adapted to living in the rain shadow have much more drought tolerance. Depending if you are zone 7, 8 or 9 you'll have the best result if you look for genetics from similar zone and rainfall. Good luck!

We get around 750mm a year but we have a very dry summer with almost no rainfall at all so would need something fairly drought hardy. I'll see what I can find with others locally who are having success.
Oh interesting, that sounds similar to our climate here! Summer is our arid dry season as well.
