Pear ,Apple, Stone Fruit, Zone or Chill Hours

I have heard it said that chill hours and zone requirements can be slightly over looked on apples, and to stick to them on stone fruit, but what about pears? I am in zone 9b in Arizona and would like to try pears, I have Asian pears but would like to try the commonly found Bartlett, Anjou or Bosc pears but the highest rating for them is zone 8, is it ok to fudge when it comes to pears?

I've never heard one way or another on the higher chilling pears in a low chill area. That makes me think you'd be way safer with things like Flordahome and Hood.

We are quite a bit cooler than you here, about 700-800 hrs below 45F. But it's the same type weather as much of AZ, mild days and cold nights in winter. Bosc and Comice took about 6-8 years to start bearing. The trees grow fine without the symptoms of lack of chilling that most apples show here.

The handful of people that I know in Phoenix that have tried haven't been very successful. Despite 4 to 5 years on OHxF87, only one individual has been able to grow a handful of very small pears. In general, only select Asians and Asian hybrids (Kieffer), tend to produce in the Valley. Most of the time, with the exception of Kieffer, pears fail to size up, likely due to the heat. Out in the colder areas of Maricopa County (Wickenberg and north, around Yarnell), you can grow them.
