Growing Brussels Sprouts in Zone 9A

Brussels sprouts need a long growing season but frost dramatically improves their flavor.

Zone 9A has a very long growing season with mild winters. Many crops can be grown nearly year-round with successive plantings.

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

Companion Planting
