Blueberries like a very acid soil like azaleas and rhododendrons

Highbush must have acidic soil and prefers a pH just below 5. Rabbiteye will tolerate a higher pH to 5.5 or more. All blueberries need well-drained soil, and do best if heavy clay or sandy soils have a good deal of organic matter added to them. Given good acid soil, both are relatively pest and disease free.
