Growing Guide

🌱 Planting

  • Start seeds indoors 6-8 weeks before last frost
  • Transplant when soil reaches 65°F (18°C)
  • Space plants 18-24 inches apart
  • Plant in well-draining, rich soil with pH 6.0-6.8

💧 Water & Soil

  • Water deeply 1-2 inches per week
  • Mulch to retain moisture and prevent weeds
  • Consistent watering prevents fruit cracking
  • Avoid wetting foliage to prevent disease

☀️ Light & Temperature

  • Requires 6-8 hours of direct sunlight daily
  • Ideal temperatures: 70-85°F (21-29°C)
  • Protect from strong winds
  • Use row covers in cooler climates

🌿 Care & Maintenance

  • Stake or cage plants for support
  • Prune suckers below the first flower cluster
  • Fertilize every 2-3 weeks during fruiting
  • Monitor for common pests and diseases

Harvesting & Storage

🍅 When to Harvest

  • Harvest when fully colored but still firm
  • Ripe when gently pressed gives slightly
  • Best flavor developed at room temperature
  • Check daily during peak season

🏠 Storage Tips

  • Store at room temperature out of direct sun
  • Avoid refrigeration (cold ruins flavor/texture)
  • Use within 5-7 days for best quality
  • Can be frozen, canned, or dried for preservation

Troubleshooting Guide

🐛 Common Pests

  • Hornworms: Hand-pick or use Bt
  • Aphids: Spray with soapy water
  • Whiteflies: Use yellow sticky traps
  • Spider Mites: Increase humidity, use neem oil

🦠 Common Diseases

  • Early Blight: Remove affected leaves, improve airflow
  • Blossom End Rot: Ensure consistent calcium supply

Selecting Your Bean Variety: A Strategic Approach

Understanding Bean Types

Successful bean cultivation starts with choosing the right variety for your garden's microclimate and personal preferences:

Bush Beans

  • Compact, self-supporting plants
  • Perfect for small gardens and containers
  • Quick maturation (50-55 days)
  • Continuous harvesting potential
  • Ideal for beginner gardeners

Pole Beans

  • Vertical growth requiring trellising
  • Higher overall yield
  • Extended harvest period
  • More complex cultivation
  • Better for experienced gardeners with vertical space

Strategic Planting Calendar

Timing Your Bean Cultivation

  • Wait until soil temperatures consistently reach 60°F
  • Plant 1-2 weeks after last spring frost
  • Recommended planting windows: Late May to early June
  • Successive plantings every 2-3 weeks for continuous harvest
