  • Care
    Care Information
    Provide fertile, mildly acidic, well-drained soil. Best in cool summer regions. Water deeply, regularly in first growing season to establish root system. Feed before new growth begins in spring. After harvest, prune to ground older canes that have fruited, leaving one-year-old canes to produce next season's crop. Train newer canes on a trellis.

  • History & Lore
    'Prime-Jim' was released in 2004 from the University of Arkansas breeding program. It is one of the first cultivars of primocane fruiting blackberry. It grows much like the other erect cultivars however the canes that emerge in the spring will flower in mid-summer and fruit in late summer or fall. The fall crop has its highest quality when it ripens in cool mild climates such as in California or the Pacific Northwest.
    Blackberries are notable for their high nutritional contents of dietary fiber, vitamin C, vitamin K, folic acid - a B vitamin, and the essential mineral, manganese.
