Avocados are like weeds. You've never been to the bay area? Its z 10a. A guy in Hayward was in the paper for growing pineapples in his front yard. Edible banana's. With me,its finding a spot that isnt shaded by my homes. Otherwise I would be growing coconuts....Right next to my Colorado Blue Spruce. The bay does a great job to moderate the climate. 7 million people add to the urban warming.
