How to Grow Cauliflower

Cauliflower is a cool-season crop that can be grown in the spring and fall. It is packed with nutrients and can be grown using organic methods. Follow this guide to learn how to grow delicious cauliflower in your garden.

What You’ll Need

  • Cauliflower seeds or transplants
  • Well-draining soil
  • Compost
  • Watering can or hose
  • Mulch

Choosing the Right Variety

Cauliflower comes in several varieties. Some popular types include:

  • Snowball: Traditional white heads.
  • Cheddar: Orange heads with a mild flavor.
  • Graffiti: Purple heads with a nutty taste.

Preparing the Soil

Cauliflower prefers well-drained, fertile soil with a pH of 6.0-7.0. Here�s how to prepare your soil:

  1. Loosen the Soil: Till the soil to a depth of 12 inches (30 cm). Remove any stones or debris that could impede root growth.
  2. Add Compost: Mix in 2-3 inches (5-7.5 cm) of compost to improve soil fertility and structure.
  3. Add Organic Matter: Incorporate well-rotted manure or homemade compost for added nutrients.

Planting Seeds or Transplants

Cauliflower can be grown from seeds or transplants. Here�s how:

  1. Starting Indoors: Sow seeds 6-8 weeks before the last frost. Transplant seedlings outdoors after hardening off, spacing them 18-24 inches (45-60 cm) apart.
  2. Direct Sowing: Plant seeds 1/4 inch (0.6 cm) deep in rows spaced 18-24 inches (45-60 cm) apart. Thin seedlings to 18-24 inches (45-60 cm) apart once they have a few true leaves.

Watering and Care

Cauliflower needs consistent watering and care. Follow these tips:

  • Water Regularly: Keep the soil consistently moist, but not waterlogged. Water in the morning to reduce evaporation.
  • Mulch: Apply a layer of mulch around the plants to retain moisture and suppress weeds.


Cauliflower benefits from organic fertilization. Use compost tea or fish emulsion every 3-4 weeks during the growing season.


Cauliflower is ready to harvest when the heads are firm and tight. Here�s how to harvest:

  • Check Regularly: Harvest cauliflower when the heads are fully formed and tight. Use a sharp knife to cut the heads from the plant.

Storing Cauliflower

Cauliflower can be stored in several ways:

  • In the Fridge: Store fresh cauliflower in a plastic bag in the refrigerator crisper drawer. Use within 1-2 weeks.
  • Freezing: Blanch cauliflower in boiling water for 2-3 minutes, then cool in ice water. Freeze in airtight containers for up to 6 months.

Tips and Tricks

  • Blanching: To keep the heads white, tie the leaves over the heads to protect them from the sun.
  • Companion Planting: Grow cauliflower with beans, celery, or herbs to maximize garden space.


Growing cauliflower using organic methods will help you achieve a bountiful harvest of delicious, homegrown cauliflower. With proper care and attention, you can enjoy fresh cauliflower from your garden all season long.
