Patent ID: 8327578

Claim:
A process for growing blackberries comprising: a vertical support structure, training a blackberry shoot to extend horizontally adjacent to said vertical support structure and thereby developing a horizontally extending primocane; allowing at least one vertically extending secondary proximal blackberry shoot to emerge from the primocane; training the secondary shoot to grow vertically on, up and over said support structure; burying an end portion of the secondary shoot in a planting medium so that the end portion develops into a new root system; severing the secondary shoot and thereby creating proximal and distal portions of the secondary shoot, the proximal portion remaining attached to the primocane and the distal portion comprising the new root system and being independent of the proximal portion and the primocane; subjecting the distal portion to a chilling period; and warming the distal portion so that the distal portion produces blackberries in an off-season month.
