LoreBlackberries are notable for their high nutritional contents of dietary fiber, vitamin C, vitamin K, folic acid - a B vitamin, and the essential mineral, manganese. Blackberries are essentially divided into two groups - primocane-fruiting and floricane-fruiting. Primocane-fruiting varieties produce flowers and fruit on canes that mature within their first year. Conversely, floricane-fruiting varieties, that do not develop any flowers or fruit on those primocanes, but rather the primocanes would be the subsequent year's floricanes, that will produce the flower and fruit. Generally, primocanes produce their fruit later in the season. A mix of floricane and primocane-producing plants in the garden provides an early season crop and a late season crop, ensuring an extended season of fresh fruit. Primocanes can be more heat sensitive and will produce best in regions that do not have excessively hot temperatures during the flower and fruit set.
Average Size at MaturityCanes reach 4 to 8 ft. tall, 3 to 6 ft. wide; prune to keep smaller.

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