This helps. Blueberries are an excellent garden fruit that do take extra soil preparation and the like. but once established, they produce productively all summer far longer than any other fruit without special hybridization.
I can see them been a mainstay everywhere. In many ways they are really just getting going. The raisin forms also works very well as well and can be used in many blends.
In the Vancouver lower mainland i have watched field after field been switched over year by year. This happens to be no small decision as no other crop is then entertained ever. There is no rotation although something could be done if one insisted but without much improvement..
