Contrary to popular belief, soil pH is not dependent on what is growing in that area - the oaks and pines do not make the soil acidic but rather the underlying mineral content of the soil and the amount of rainfall you receive. The pines and oaks only grow there because the existing pH is to their liking. Blueberries will grow well in soils that have a pH of 6.0 or lower. Many sites will insist on a pH of 5.5 or less but we support a very large commercial blueberry industry in my area in only mildly acidic soils.

The sandy soil could cause issues. Blueberries like a soil that is consistently moist and with plenty of organic matter - a very sandy soil provides little of either so you may need to amend to improve those conditions.

As to varieties, there are many excellent cultivars of southern highbush and rabbit-eye, both of which thrive in southern climates. Local nursery outlets should carry a good selection.
