Availability of soil moisture is the most importance factor to consider in choosing a planting site for blackberry.
Almost any soil type, except very sandy soils, is suitable for blackberries as long as the drainage is good.
Blackberries are for the most part rank-growing pants and require liberal distances in and between the rows.
A common planting, plant erect varieties of blackberries five feet apart in the row, and eight to ten feet between the rows. Space vigorous varieties of trailing or semi-trailing blackberries such as Thornless Evergreen, eight to 12 feet apart in rows, that are 10 feet apart.
The tillage of the blackberry plantation should be such as to hold weeds and suckers in check and maintain maximum moisture and growth conditions, but cultivation should cease early enough to induce the plants to ripen their wood thorough before winter.
