Planting Systems

Conventional row system:

  • In-row: 4-6 feet
  • Between rows: 10-12 feet
  • Plants per acre: 605-1,089

High-density system:

  • In-row: 3-4 feet
  • Between rows: 8-10 feet
  • Plants per acre: 1,089-1,815

Hedgerow system (for mechanical harvest):

  • In-row: 3 feet
  • Between rows: 12-14 feet
  • Managed as continuous hedgerow

Fertigation Programs

Year 1 (establishment):

  • Limited nitrogen (30-40 lbs N/acre)
  • Emphasis on root development
  • Weekly small doses preferred

Years 2-3 (building):

  • 60-80 lbs N/acre
  • Split applications
  • Include P and K based on soil tests

Mature plantings:

  • 80-100 lbs N/acre
  • Potassium critical for fruit quality
  • Annual tissue and soil testing

Pruning Systems for Production

American Elderberry Pruning Options

Option 1: Complete renewal (cutting to ground)

  • Cut all canes to ground in late winter
  • 100% new growth each year
  • Simplest system
  • Delays harvest slightly
  • Prevents borer buildup

Option 2: Selective cane removal

  • Keep 5-8 canes per plant
  • Remove canes >3 years old
  • Remove weak, crossing canes
  • Maintains earlier harvest
  • Requires more skill

Option 3: Hedgerow management

  • Mechanical hedging
  • Annual topping at 4-5 feet
  • Side trimming for row width
  • Compatible with mechanical harvest

European Elderberry Pruning

  • Never use complete renewal (no fruit!)
  • Remove 2-3 oldest canes annually
  • Maintain 6-8 productive canes
  • Head back long growth
  • Open center for light and air

Pneumatic combs50-100 lbs/hour/personGood$500-2,000

Harvest Quality Management

Pre-harvest assessment:

  1. Brix testing (minimum 11-12%)
  2. Color evaluation
  3. Maturity uniformity
  4. Pest and disease check

Harvest timing factors:

  • Morning harvest preferred (cooler)
  • Avoid wet conditions
  • Harvest at full maturity
  • Multiple passes may be needed
