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!
