Seed Starting

Seed starting is the practice of germinating seeds indoors under controlled conditions and then transplanting the young seedlings outdoors into the garden.

Importance in Gardening

  • Early Start: Allows gardeners to start the growing season early, giving plants a head start before the outdoor growing conditions are suitable.
  • Control Over Conditions: Provides a controlled environment for optimal germination and early growth, leading to healthier seedlings.
  • Variety: Enables gardeners to grow a wider variety of plants, including those not commonly available as transplants.

Steps for Seed Starting

  1. Choosing Seeds:
    • Select high-quality seeds suitable for indoor germination.
    • Consider the germination time and growing conditions for each plant type.
  2. Preparing Containers:
    • Use seed trays, pots, or recycled containers with drainage holes.
    • Clean containers to prevent disease.
  3. Using Seed Starting Mix:
    • Fill containers with a sterile, well-draining seed starting mix.
    • Moisten the mix before planting seeds.
  4. Sowing Seeds:
    • Plant seeds at the recommended depth, typically 2-3 times their diameter.
    • Space seeds according to the instructions on the seed packet.
  5. Providing Light:
    • Place containers in a bright location or under grow lights.
    • Ensure seedlings receive 12-16 hours of light daily.
  6. Maintaining Moisture:
    • Keep the soil consistently moist but not waterlogged.
    • Cover containers with plastic wrap or a humidity dome to retain moisture until seeds germinate.
  7. Temperature Control:
    • Maintain a warm temperature (65-75°F) to encourage germination.
    • Use a heat mat if necessary.
  8. Thinning Seedlings:
    • Once seedlings have true leaves, thin them to prevent overcrowding.
    • Remove weaker seedlings to give stronger ones more space.
  9. Hardening Off:
    • Gradually acclimate seedlings to outdoor conditions over 1-2 weeks.
    • Start by placing them outdoors in a shaded area for a few hours, gradually increasing exposure to sunlight and outdoor temperatures.
  10. Transplanting Outdoors:
    • Transplant seedlings into the garden after the last frost date when the soil is warm.
    • Water thoroughly after transplanting and protect from harsh conditions initially.
