Wild blackberries are a traditional fruit crop in the South.
The erect or upright blackberry is the most popular type grown in Mississippi. Erect varieties require less labor and expense since no trellis system is needed. Establishment and Cultural Practices Blackberries grow on a wide range of soil types. A soil pH of 6.0 to 6.5 is best, but blackberries grow in soils ranging from a pH 4.5 to 7.5. Establish erect blackberries in late February or early March by planting root cuttings collected from healthy plants.
