I'm near Knoxville and have done countless soil testing for several
properties--all very acidic. I also do a lot of mountain hiking and
there are many wild blueberries. Out soil is generally clay.
Blueberry bushes can be purchase in late winter in local stores. Mix
cotton meal into the soil and mulch with old partially rotted sawdust
or peat moss. Watch for loss of green in the leaves ("anemia") then
feed with an acidic fertilizer at half strength, and then only when
the plant has been established (about a year). Blueberry roots are
very tender. Plant 3 or 4 varieties 4 feet apart for improved yields.
You will have to use plastic bird netting.
