Growing Cauliflower in Zone 6B

Cauliflower is the most challenging brassica but produces beautiful heads when conditions are right.

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

Top Growing Tips

• Needs consistent cool temperatures (60-70°F) — very temperature sensitive
• Blanch heads by tying outer leaves over the curd when it’s 2-3 inches
• Any stress (heat, drought, cold snap) can cause buttoning (tiny heads)
• Self-blanching varieties are easier for beginners
• Fall crops are generally more reliable than spring in most zones

Companion Planting

Good companions: beets, celery, onions, spinach

Avoid planting near: tomatoes, peppers, strawberries

Harvest Timeline

55-80 days from transplant
