Commercial Currant Production

With growing demand for "superfruits" and locally-produced berries, currants present opportunities for specialty crop production. This advanced guide covers commercial production systems, mechanization, regulatory considerations, and market development strategies.

Planting Systems

Conventional row system:

  • In-row: 3-4 feet (red/white), 4-5 feet (black)
  • Between rows: 10-12 feet
  • Plants per acre: 900-1,400

Hedgerow system (mechanical harvest):

  • In-row: 2-3 feet
  • Between rows: 12-14 feet
  • Managed as continuous row
  • Plants per acre: 1,200-1,800

Pruning for Production

Red/White currant commercial pruning:

Annual operations (late winter):

  1. Remove all wood >3 years old
  2. Thin to 8-12 canes per plant
  3. Head leaders to maintain height
  4. Remove weak interior growth
  5. Target 3-4 canes each of 1, 2, 3 year wood
