We've recently purchased a single blueberry bush and now are told we need two to make things "work right" so to speak,we have blackberry, raspberry and allmost a dozen fruit trees in the visinity[?] would these others be enough to pollinate the blueberry or do we need a second bush?
Matter of birds and the bees. :) They are not self pollinating so they need another of their kind or even a whole harem of varieties http://edis.ifas.ufl.edu/HS220 http://gears.tucson.ars.ag.gov/book/chap7/blue.html Liz
Shouldn't be a problem, as long as you have a few native species of blueberries nearby. Pollinators are bumblebees - so your single bush needs to be within the foraging range of the wild species.
