📅

Days to maturity: 50-65 days from transplant (100-120 days from seed)

🌱

Planting depth: 1/4 inch for seeds; transplants at same depth as in starter pot

Soil

Type: Well-draining, fertile loamy soil rich in organic matter

pH: 6.0-7.5

Growth Stages

Seedling

2-3 weeks

Tiny true leaves emerge from cotyledons; plant is delicate and pale green

Start seeds indoors 4-6 weeks before last frost. Keep soil moist, provide bright light (12-14 hours), maintain 65-70°F. Thin seedlings to prevent damping off. Avoid overcrowding

Transplant/Establishment

2-3 weeks

Young plants develop 4-6 true leaves and strengthen; ready for field planting when 3-4 inches tall

Harden off gradually over 7-10 days before transplanting outdoors. Plant in cool weather (spring or late summer). Water gently after transplanting. Mulch around base to retain moisture

Vegetative Growth

3-4 weeks

Large, blue-green leaves develop and plant expands; no curd visible yet. Plant grows to 18-24 inches tall

Water consistently and deeply. Apply balanced fertilizer every 2-3 weeks. Keep weed-free. Monitor for cabbage worms and aphids. Maintain steady 60-70°F temperature for optimal growth

Curd Formation & Development

2-3 weeks

Compact white head (curd) begins forming at center of plant; rapidly enlarges and becomes dense. Curds reach 4-6 inches diameter at maturity

Increase nitrogen fertilizer slightly. Water more frequently (daily in heat). Tie outer leaves over curd to blanch and protect from sun (prevents yellowing/browning). Check for clubroot and other diseases

Harvest Maturity

2-3 days optimal window

Curd is compact, dense, bright white, and dome-shaped. Florets are tightly packed with no separation or flowering

Monitor daily once heads reach 4-5 inches. Harvest before florets begin to separate or yellow. Cut with 2-3 inches of stem and some leaves for freshness. Early morning harvest captures best quality

Common Pests

Row covers over young plants. Hand-pick caterpillars. Bacillus thuringiensis (Bt) spray weekly. Neem oil for light infestations
Row covers. Hand-picking. Bt spray. Monitor undersides of leaves for eggs and young caterpillars
Row covers for seedlings and young plants. Kaolin clay spray. Insecticidal soap. Diatomaceous earth around base
Strong water spray to dislodge. Insecticidal soap. Neem oil. Encourage natural predators (ladybugs, lacewings)
Improve soil drainage. Raise pH to 7.0-7.5 with lime. Do not plant brassicas in same spot for 4-5 years. Remove and destroy affected plants
Use disease-free seeds. Avoid overhead watering. Remove affected leaves. Rotate crops. No chemical cure; prevention is key

Uses

🍳

Fresh Cooking & Roasting

💊

Nutritional & Cancer Prevention

Medicinal

Cauliflower is rich in vitamin C, folate, and antioxidants. Research suggests glucosinolates and sulforaphane compounds in brassicas may support cancer prevention and cardiovascular health. [source]

🏠

Vitamins & Dietary Health

Household

A low-calorie, nutrient-dense vegetable high in fiber, potassium, and B vitamins. Supports digestive health, bone strength, and weight management in a balanced diet. [source]

🦋

Pollinator Support

Wildlife

If allowed to flower, cauliflower blooms attract bees and beneficial insects. Leaving a few plants to bolt provides late-season nectar and pollen for pollinators. [source]

Harvest Tips

Cut curds when heads are compact, dense, and 4-6 inches in diameter, before florets begin to separate or show any yellowing. Harvest early morning for crispness and best quality. Include 2-3 inches of stem and several leaves to protect the tender curd. Head remains harvestable for only 3-5 days at peak quality, so check plants daily once sizing begins

Fun Facts

🌱 Early Snowball A was introduced in the 1880s and remains one of the most reliable and widely-grown cauliflower varieties for home gardeners after 140+ years.
🌱 The white color of cauliflower curds comes from a lack of chlorophyll; gardeners 'blanch' the head by tying leaves over it to shield it from sunlight, which keeps it pure white and tender.
🌱 Cauliflower is actually an immature flower cluster (curd) harvested before the tiny flowers bloom and separate—it's essentially an edible bouquet of unopened flower buds.
