Growth Stages

1

Seedling

7-14 days

Tiny cotyledons emerge, developing true leaves with the characteristic Brassica texture. Plant is very delicate.

Keep soil moist but not soggy. Provide bright light (grow lights if indoors). Maintain 65-75°F. Thin seedlings to prevent crowding.

2

Vegetative Growth

3-4 weeks indoors; 2-3 weeks after transplanting outdoors

Plant develops 4-8 true leaves, growing vigorously with a sturdy stem. Leaves are blue-green and deeply lobed.

Harden off transplants over 7-10 days before planting outdoors. Keep consistently moist. Apply balanced fertilizer every 2-3 weeks. Protect from pests with row covers if needed.

3

Head Initiation & Development

2-3 weeks

Central growing point begins forming a compact, white, cauliflower-like head (curd). Surrounding leaves grow larger and support the developing head.

Ensure consistent watering—critical for uniform, tight heads. Apply side-dressing of compost or balanced fertilizer. Begin blanching when head is 2-3 inches across by loosely tying outer leaves over the curd to keep it white and tender.

4

Head Maturation

1-2 weeks

Head swells rapidly, curds tighten and become dense. Head should reach 4-6 inches diameter with a compact, snowball-like appearance.

Maintain blanching by keeping leaves tied or pulled over the head. Continue consistent watering. Watch for premature flowering (bolting) if temperatures spike above 75°F. Harvest when head is firm and curds are tight, before they begin to separate.

5

Harvest

Harvest window 3-5 days

Head reaches market-ready size (4-6 inches), snow-white color, and tight, dense curds. Ready to cut and use.

Cut the main head with 2-3 inches of stem attached. Check for secondary heads that may develop after the main head is harvested. Use fresh or store in cool conditions.

Companion Planting

Plan your garden →

Plant with:

Basil beets celery chamomile dill garlic marigold nasturtium onion thyme

Avoid planting near:

Fennel kohlrabi other Brassicas (cabbage, broccoli, kale) strawberry tomato

Common Pests

  • Row covers until flowering. Bt (Bacillus thuringiensis) spray weekly. Hand-pick larvae. Encourage parasitic wasps.

  • Bt spray. Neem oil. Handpick. Companion plantings like dill attract parasitoid wasps.

  • Row covers on young plants. Diatomaceous earth. Neem oil. Reflective mulches. Remove damaged leaves.

  • Crop rotation (3-4 years). Raise soil pH to 7+. Use resistant varieties if available. Avoid waterlogging. Solarize soil.

  • Ensure good air circulation. Sulfur dust or spray. Neem oil. Avoid overhead watering. Remove affected leaves.

Harvest Tips

Harvest when the head is 4-6 inches in diameter, dense, and firm, with tight curds and bright white color. Squeeze gently—a properly mature head will feel solid. Cut with a sharp knife, leaving 2-3 inches of stem and some wrapper leaves. In cool weather, heads can be left on the plant a few days longer. Secondary mini-heads often develop after the main head is harvested. Best harvested in early morning when crisp. Store at 32°F and high humidity for up to 1 week, or blanch and freeze for longer storage.

Fun Facts

  • 🌱 Early Snowball A is an heirloom variety dating back to the 1880s, bred for reliable early maturity and beautiful white heads—the whiteness comes from blanching (shading the curd from sunlight), which prevents chlorophyll development.
  • 🌱 Cauliflower is technically an immature flower bud cluster; if left unharvested, the 'curd' will elongate into yellow flowers and eventually produce seeds.
  • 🌱 The name 'Snowball' perfectly describes the round, compact head shape, and this variety was historically one of the most popular choices for American home gardeners due to its speed and consistency.
