What to know before you act on this, from the SteadScape editors.

  • Start Brussels sprouts indoors 6 to 8 weeks before the last frost date for optimal growth in cooler conditions.
  • Space seedlings 18 to 24 inches apart and thin to one plant per pair when they reach 3 inches tall to ensure healthy development.
  • Apply a balanced organic fertilizer when seedlings are 12 inches tall to promote sprout formation without over-fertilizing.
  • Use floating row covers immediately after planting to protect young plants from pests and frost damage during early growth stages.
  • Harvest Brussels sprouts after the first frost for the best flavor, ideally waiting until temperatures drop to around 10°F (-12°C).
