When to Start Seeds Indoors:

  • Begin 6-8 weeks before the last expected frost date in your area.

Preparing Seed Trays and Soil Mix:

  • Fill seed trays or small pots with seed starting mix.
  • Moisten the soil before planting.

Planting the Seeds:

  • Sow seeds ¼ inch deep in the soil.
  • Cover lightly with soil and gently press down.

Germination Tips:

  • Place trays in a warm location, ideally between 70-80°F (21-27°C).
  • Keep the soil consistently moist but not waterlogged.
  • Provide 12-16 hours of light daily using grow lights or a sunny windowsill.
Step 2: Transplanting Seedlings

When to Transplant Seedlings:

  • Transplant seedlings when they have at least two sets of true leaves and after the last frost date.

Preparing the Garden Bed or Containers:

  • Choose a sunny location with well-draining soil.
  • Amend the soil with compost or aged manure to provide nutrients.

Hardening Off Seedlings:

Planting in the Ground or Pots:

  • Water deeply and regularly, keeping the soil evenly moist.

Fertilization:

Managing Pests and Diseases:
