  • Zone 6+: Good potential with proper planning

What Brussels Sprouts Need to Succeed

  • Long growing season (90–120+ days)
  • Cool temperatures for best sprout development
  • Consistent moisture and fertile soil
  • Steady growth without heat stress

Timing Matters in Canada

  • Start indoors early in spring
  • Transplant after frost
  • Harvest improves after light frost in fall
