Site Selection
Appropriate climate
Accessible
Well drained surface & soil
Humus >3%
Low pH: 4.5 – 5.2
At least 1/2 day full sun
Irrigation available
        Site Preparation
• Begin at least one year before planting
• Control perennial weeds with non-
  residual herbicides and repeated
  cultivation
• Soil test
  – Adjust pH per soil test
  – Add P & K fertilizer as per soil test
• Add organic matter if necessary
• Improve drainage
• Prepare irrigation
                    2-year old container
                           grown plants




Loosen roots




               Remove blossom and
               green fruit at planting
               Planting System
• Spacing
  – Plants: 1 – 1.2 m spacing in the row
  – Rows: 3m between rows
• Raised Beds
  – For improved drainage on heavier soils
• Mulch
• Irrigation
  – Drip irrigation is best
        1.2m between bushes
         x 3m between rows

          Mulch
• Mulches are desirable for:
  –   Retaining moisture
  –   Keeping soil surface cool
  –   Protecting roots
  –   Reducing weeds
  –   Increasing organic matter
• Sawdust, shavings, bark, or clean straw
• Plant sod between rows
  – Non-creeping grasses
  – Maintain with mowing. Do not allow to seed
         Irrigation
• Supplemental irrigation critical
• Drip irrigation recommended
• Water source
   Flow rate and recharge
   pH
   Quality
• Schedule 2.5 - 4 cm / week
When berries are ready to pick…
     Harvest should be
     •   Timely
     •   Dry
     •   Clean
     •   Gentle
Highbush Blueberries
   are usually picked by hand for
   fresh markets




            a pail on a neck-strap
            or belt is often used
    Pre-cool Harvested Berries
• Field heat can activate fruit disease organisms
  within 12 hours
• Harvested fruit respires after being picked
  causing a rise in temperature of as much as
  7C… unless checked by cooling
• Blueberries at 27C respire 20X faster than
  berries at 4C
• Pre-cool within four hours of harvest using a
  convection cold-air tunnel system
