Pro Tip

For large, tender cauliflower heads, practice blanching by tying the outer leaves over the developing curd when it’s about 2–3 inches in diameter. This protects it from sun exposure, preventing discoloration and bitterness.

Getting to know your Cauliflower

What it's used for

1. Culinary Uses:

  • Consumed raw in salads, roasted, steamed, stir-fried, or mashed.
  • Used as a low-carb alternative (e.g., cauliflower rice, pizza crust, and cauliflower steaks).
  • Pickled or fermented for preservation.

2. Nutritional Benefits:

  • Rich in vitamin C, vitamin K, fiber, and antioxidants.
  • Supports digestion, immunity, and heart health.

3. Companion Planting:

  • Grows well with celery, onions, spinach, and beets.
  • Avoid planting near strawberries or tomatoes, which may compete for nutrients.
Growth Requirements

Light:

  • Requires full sun (6+ hours of direct sunlight per day).

Soil:

  • Prefers rich, well-draining, loamy soil with a pH of 6.0-7.0.
  • Add organic matter like compost or aged manure before planting.

Watering:

  • Needs consistent moisture, about 1-1.5 inches per week.
  • Avoid overwatering, which can cause root rot.

Temperature & Climate:

  • Best growing temperatures: 60-75°F (15-24°C).
  • Can tolerate light frost, but extreme heat can cause poor head formation (buttoning).

Fertilization:

  • Use a balanced fertilizer (10-10-10 or organic compost) at planting.
  • Side-dress with nitrogen fertilizer every 3-4 weeks for optimal growth.
Maintenance

Watering:

  • Keep the soil evenly moist, but avoid soggy conditions.
  • Mulch with straw or compost to retain moisture and regulate soil temperature.

Fertilization:

  • Feed with a balanced fertilizer (10-10-10) every 3-4 weeks.
  • Apply calcium-rich amendments to prevent hollow stems or tip burn.

Blanching (For White Cauliflower):

  • To keep the curd white, tie outer leaves over the head when it reaches 2-3 inches in diameter.

Harvesting and Seed Collection

  1. When to Harvest:
    Cauliflower is ready 60-100 days after planting, depending on variety.
    Harvest when the head is 6-8 inches in diameter and firm.
    Cut the head at the base with a sharp knife, leaving a few outer leaves attached.
  2. Storing Cauliflower:
    Store in the refrigerator for up to 2 weeks.
    Can be blanched and frozen for long-term storage.
  3. Saving Seeds:
    Allow plants to flower and set seed in their second year.
    Collect dried seed pods, store in a cool, dry place, and replant next season.
