Growing Brussels Sprouts in Zone 10B

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
