Ideal soils for blackberry production are deep and well drained with a sandy to loamy texture. Blackberries tolerate soils being slightly acidic (pH between 5.6 and 6.8) with a preferred range of 6.0-6.5. Alkaline soils can create micronutrient problems, particularly iron chlorosis.

 

Blackberry cultivars are adapted to most climates zones. Winter injuries can occur at -15°C for thornless varieties while all the other varieties can resist up to -20°C. For an optimum plant growth, blackberries enjoy long sunny days (minimum 13 hours/ day). Nevertheless excessive heat during ripening can cause soft, poorly colored fruit and increase the likelihood of sunscald on the berries. Due to its strong root system, blackberries can support periods of drought but for obtaining maximum yields it requires minimum of 700 mm of rainfall/year.
