Low chill bluberries for AZ zone 9b Sunset 13
I am looking for a few varieties of low chill blueberries (southern highbush), that will survive in the low desert. I have a legacy that I purchased last year on clearance, that survived but I cannot say it thrived, the oneal I bought died as soon as it started to heat up, I have seen pink lemonade in stores here and read it may be self fruitful, but the varieties that would pollinate it are rabbiteye and northern highbush that will not survive here. I am interested in sweetcrisp as I have read that it is low chill and a good berry. The real issues I have to deal with are extreme summer temps and low chill hours, this winter in particular has been extremely mild.
I have the legacy in a container with peat, and plan to do the same with the others.
If there isn't much hope I would like to know that as well, I have tried to stretch zone limits on a few things before without much luck.
