CARE
Care Provide fertile, mildly acidic, well-drained soil. In hot summer regions, shelter from harsh sun, and mulch to keep roots cool. Water deeply, regularly in first growing season to establish extensive root system. Feed in early spring. After harvest, remove canes that have fruited. Leave newer canes to produce next season's crop; train on a trellis.
HISTORY
Lore The name blackberry is a misnomer because this isn't a true berry. It's a drupe, an entirely different sort of fruit.
