However, for profitable production, good management is essential. Small commercial plantings of blackberries are scattered throughout Texas.
Blackberries are biennials and begin bearing the year after planting.
The first year they can bear 2,000 pounds per acre, or about 8 gallons per 100 feet of row. Good yields range from 5,000 to 10,000 pounds per acre. On soils with a pH of 8.0 or above, plants will experience severe iron chlorosis and chelate will be needed. If internal soil drainage is not fast, grow blackberries in a raised bed. Rainfall or irrigation will be needed weekly.
