Tips for Growing Blackberries


Blackberries are considered to be perennial plants as their roots will live indefinitely. Each year this plant will send up new canes that will produce fruit in its second year of life.

Therefore, each blackberry cane will live for 2 years. After you harvest blackberries from that cane in the 2nd year, you will then trim that cane down to ground level as it will have completed its life cycle.

Make sure not to cut any or too many of the new canes that are on their first year's growth as they will be the ones that you will be harvesting from next season.

  • Requires well-drained, fertile, and moisture-retentive soil
  • Likes full sun, but can tolerate partial shade
  • Requires 1 to 2 inches of water per week
  • Adding a good layer of mulch will help keep more moisture near your plant's root system
  • Space your plants approx. 4 to 8 feet apart depending on the variety
