@Alan: This is very interesting.  How can one add sufficient levels of
magnesium to the soil?  Epsom salt?  Also, this is an idea: if pH is not
the real issue, and the absence of enough Mg is, why can't one add Dolomite
limestone to the soil for blueberries; higher pH and higher Mg would result.

@everyone: There are two varieties of northern high-bush bluery (V.
corymbosum)  that I know of that can take more typical garden soil (clay,
higher pH)...

1. Jersey
2. Hardiblue

I think Reka too, and just read about one called Sunshine[something].  Does
anyone know any others.
