Growing Brussels Sprouts in Zone 5B

Zone 5B has a moderate growing season. Most crops do well here with proper timing around frost dates.

Top Growing Tips

• Start indoors in spring for fall harvest — they need 80-100 days
• Remove lower leaves as sprouts develop to improve air circulation
• Top the plant 3-4 weeks before expected harvest to speed maturity
• Harvest from bottom up as sprouts reach 1-2 inches
• Flavor is best after several hard frosts
