Blueberry

Category: berries

Growing

  • 📍 Zone: 3-10 (depending on variety)
  • 🌞 Sun: Full sun
  • 💧 Water: Consistently moist; does not tolerate drought well, especially when fruiting
  • 🌱 Soil: Rich, moisture-retentive, acidic soil (pH 4.5-5.5); amend with peat moss or pine needles if needed

Planting

  • 📏 Height: Highbush: 6-8 feet; Lowbush: 1-2 feet
  • 📏 Spacing: Highbush: 4-5 feet apart; Lowbush: 2-3 feet apart
  • 📅 When To Plant: Plant in early spring as soon as the soil can be worked
  • 🌱 Propagation: Typically propagated by cuttings; layering or suckers can also be used (lowbush spreads by underground rhizomes)
  • ⬇️ Depth: Medium; plant at the same depth as in nursery pot or slightly deeper if bare-root
  • 🤝 Companion:
    • 0: Other blueberry varieties (cross-pollination improves yield and berry size)
  • 🚫 Avoid Planting Near:
    • 0: Nightshades (e.g., potatoes, tomatoes, peppers)

Care & Maintenance

  • ✂️ Pruning:
    • 0: Prune in late winter while dormant
    • 1: No pruning during the first 2 years except to remove dead or weak growth
    • 2: Remove flower buds the first 2 years to encourage strong vegetative growth
    • 3: For highbush: remove oldest canes after year 5 to promote new growth
    • 4: For lowbush: mow or cut plants to ground every 2-3 years after harvest to rejuvenate
  • Notes: Mulch with pine bark, sawdust, or wood chips to conserve moisture and maintain acidity

Harvesting & Usage

  • When To Harvest: When berries are fully blue, plump, and easily detach from the plant, typically mid to late summer depending on variety
  • How To Harvest: Gently roll berries between fingers or palm; they should fall off easily when ripe
  • 🥫 Preservation: Freeze, dry, or make into jams and jellies; fresh berries can store in the fridge for up to 10 days

  • 🐝 Pollinators:
    • 0: Bees (essential for good fruit set)
    • 1: Bumblebees and native solitary bees particularly effective
