It's interesting what you can do with good blueberries! :-)
Here in Upper Michigan, south of Lake Superior, some of the best wild blueberry picking I've run across has been in areas with sandy soil and jack pine trees. The wild blueberry bushes seem to like the more acidic soil around pine trees, as long as they can get some sunlight.
I have 4 high bush blueberry bushes planted in a raised bed on the edge of the yard, 3 different varieties. I planted them last year and they all made it through the winter. Only 1 of them had any blueberries on it, but I wasn't expecting any blueberries this year, the bushes are still pretty small.
