Hello, I live in Marana, which is just north of Tucson. We are down in the flatlands and get a little hotter in the summer, and also a little colder in the winter. So more chill hours, but also more intense heat, not to mention some wicked winds. (Why do I live here again??) Anyway, I know it's possible to grow pears here because my vet has a big pear tree on his property, which is just a mile or so down the road. Any advice on a good variety that is low chill and can take the heat and sun? I did a little reasearch and I'm thinking Kieffer. Any experience?
