Cauliflower (Brassica oleracea var. botrytis) is a nutrient-rich cool-season vegetable belonging to the Brassicaceae family, which includes broccoli, cabbage, and Brussels sprouts. Known for its compact white curd (head), cauliflower is prized for its versatility, mild flavor, and high vitamin C content. Cauliflower is a delicious, nutrient-dense vegetable that thrives in cool temperatures and rich soil. Whether started from seeds indoors or sown directly outdoors, it requires consistent watering, blanching gardeners can enjoy fresh, homegrown cauliflower in their meals throughout the growing season.

How to Plant Cauliflower from Seed

When to Plant Seeds

  • Spring Crop: Start seeds indoors 4-6 weeks before the last frost date.
  • Fall Crop: Directly sow seeds 8-10 weeks before the first expected frost.
  • Succession Planting: Plant every 2-3 weeks for a continuous harvest.

Preparing for Planting

  1. Select a sunny, well-drained site with nutrient-rich soil.
  2. Loosen soil 12 inches deep and mix in organic compost or aged manure.
  3. Maintain a consistent soil pH of 6.0-7.0.

Direct Sowing Outdoors

  • Sow seeds ¼ inch deep, 12-18 inches apart, in rows spaced 24-36 inches apart.
  • Thin seedlings to 18 inches apart once they develop true leaves.

Starting Indoors

  • Sow seeds ¼ inch deep in seed trays filled with moist potting mix.
  • Maintain temperatures 65-70°F (18-21°C) for germination.
  • Seeds will germinate in 7-14 days.
  • Transplant seedlings when they have 4-5 true leaves.

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

Cauliflower is a cool-season vegetable in the Brassicaceae family, prized for its compact, edible white curds. It grows best in nutrient-rich, well-drained soil with full sun. The plant requires consistent moisture and cool temperatures to prevent premature bolting. Cauliflower heads, known as curds, develop within protective leaves that shield them from excessive sun exposure, preserving their white color. Some varieties produce orange, purple, or green curds. It is a heavy feeder, requiring ample nitrogen and phosphorus for optimal growth. Cauliflower takes 60-100 days to mature, making it more challenging to grow than other brassicas. It is used in various culinary dishes, from steaming to roasting, and is a popular low-carb substitute for rice and flour.

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.
Pests and Diseases
  • Common Pests: Cabbage loopers, aphids, flea beetles.
    Use floating row covers to protect plants.
    Spray with neem oil or insecticidal soap if needed.
  • Common Diseases: Clubroot, black rot.
    Rotate crops yearly and avoid planting cauliflower in the same spot every season.

Our Seed Safety Promise

We do not sell genetically modified seeds — ever. And we don’t use genetic engineering to breed new varieties. Instead, our skilled breeders use traditional, natural crossing methods to create hybrid seeds that are healthy, safe, and packed with potential.

Our Seed Quality Guarantee

At Shido, we believe great gardens start with great seeds — and that means quality comes first. Every seed lot we offer is ensure to generate top-notch germination because your garden deserves nothing less.

To keep our seeds at their peak, we run thorough pathology tests at trusted outside labs. When you open a Shido seed packet, you can trust it’s been nurtured, tested, and approved to give you strong, healthy plants from the very first sprout.

Types of Seeds We Offer

Hybrid Seeds (F1)

F1 hybrid seeds are the garden’s high achievers — created by crossing two specially chosen parent plants for superior vigor, uniformity, and performance. We use only traditional breeding methods to produce these powerhouse seeds.

Open-Pollinated & Heirloom Seeds

Our open-pollinated (OP) seeds naturally reproduce through wind, insects, water, or self-pollination. When grown in isolation, they produce true-to-type plants year after year.

Among our OP seeds are treasured heirloom varieties — old favorites that have been carefully passed down for generations. While OP plants can be less uniform than hybrids, we run our Open-Pollinated Project to select the most reliable, flavorful, and beautiful strains. Many are also available as certified organic seeds.

Non-GMO: What It Means and Why It Matters

GMO (Genetically Modified Organism) is created when scientists alter a plant’s DNA in a lab — often by inserting genes from completely unrelated species — to achieve certain traits, like pest resistance or herbicide tolerance. This is a far cry from natural plant breeding.

At Shido, we believe gardening should stay as close to nature as possible. All our seeds — whether hybrid, heirloom, organic, or open-pollinated — are Non-GMO. They’re bred using traditional methods that respect natural biodiversity, giving you safe, wholesome seeds that grow into plants just as nature intended.

When you plant Shido Non-GMO seeds, you’re choosing purity, sustainability, and peace of mind — along with a garden full of flavor, color, and beauty.
