Zone 6A has a moderate growing season. Most crops do well here with proper timing around frost dates.

Top Growing Tips

• Sow indoors 4 weeks before last frost or direct sow in early spring
• Prefers soil temperatures between 45-75°F — bolts quickly in heat
• Space standard varieties 6-9 inches apart; baby types can be closer
• Harvest whole heads when compact, or cut outer leaves for partial harvest
• Fall sowing is often more successful — cooler temps prevent bolting

Companion Planting

Good companions: beets, onions, celery, aromatic herbs

Avoid planting near: strawberries, pole beans, tomatoes
