Growth Stages

1

Seedling

2-3 weeks

Tiny cotyledons emerge; first true leaves appear small and wrinkled.

Maintain consistent moisture and warmth (65-70°F). Provide bright light indoors. Thin seedlings to prevent crowding.

2

Vegetative (Early Growth)

3-4 weeks

Seedlings develop 4-6 true leaves; transplants establish and begin growing rapidly.

Harden off transplants gradually before field planting. Apply steady nitrogen fertilizer every 2 weeks. Mulch to retain moisture and regulate soil temperature.

3

Head Formation (Mid-Season)

2-3 weeks

Plant forms a visible central head; outer leaves overlap to create the compact ball shape.

Monitor for pests and diseases. Ensure consistent watering. Reduce nitrogen to avoid loose heads. Watch for calcium deficiency (tip burn).

4

Head Maturation

2-3 weeks

Head becomes firm, dense, and reaches full size (2-4 lbs typically). Outer wrapper leaves remain green.

Continue steady watering. Reduce or stop fertilizing. Scout for late-season pests. Heads should feel hard when gently squeezed.

5

Harvest Ready

Variable; harvest within 1-2 weeks of maturity

Head is solid, compact, and field-tested firm. Outer leaves may show minor cosmetic marks.

Harvest when heads reach desired size and firmness. Can be left in ground briefly if weather is cool. Avoid overmature heads, which may split.

Common Pests

  • Use row covers on young plants, Bt (Bacillus thuringiensis) spray, hand-pick, or neem oil. Encourage parasitic wasps.

  • Bt spray, spinosad, row covers, and hand-picking. Monitor regularly for early detection.

  • Row covers, diatomaceous earth, neem oil, or insecticidal soap. Remove debris where they overwinter.

  • Strong water spray, insecticidal soap, neem oil, or targeted pyrethrin spray. Encourage beneficial insects.

  • Plant resistant varieties, avoid replanting brassicas in infested soil for 3-4 years, improve drainage, raise soil pH to 7+.

  • Use disease-free seeds, remove infected leaves, rotate crops, improve air circulation, avoid overhead watering.

Uses

🍳

Fresh eating and slaws

Culinary

Westar's tender, sweet leaves are excellent raw in salads, coleslaw, and slaws. The mild flavor and crisp texture make it ideal for fresh preparations without the bitterness of storage varieties. [source]

🍳

Cooking and fermentation

Culinary

Use in stir-fries, soups, stews, and braised dishes. Westar's early-maturity timing makes it excellent for spring and early summer cooking when tender cabbage is desired. [source]

💊

Phytonutrient content

Medicinal

Westar cabbage contains glucosinolates, which break down into compounds with potential anti-inflammatory and cancer-preventive properties. Raw or lightly cooked cabbage provides optimal bioavailability. [source]

🏠

Storage and preservation

Household

Westar stores reasonably well for an early variety when kept cool and humid. Suitable for short to medium-term storage (3-4 weeks) or can be fermented into sauerkraut. [source]

🦋

Insect habitat and food

Wildlife

Flowering bolts and uncultivated plants attract pollinators and beneficial insects. Cabbage plants provide shelter for ground beetles and spiders that help control garden pests. [source]

Harvest Tips

Harvest when heads are firm and reach 3-4 inches in diameter (typically 2-4 lbs). Cut heads at the base with a sharp knife just above the lowest leaves. Westar tolerates slight frosts and can be harvested late into fall. Heads store well in cool, humid conditions (32-40°F, 95% humidity) for up to 3 months. For best quality, harvest in the morning when heads are cool and turgid.

Fun Facts

  • 🌱 Westar was developed at Cornell University specifically for early harvest and disease resistance, making it one of the most reliable and widely recommended varieties for home gardeners and small farms.
  • 🌱 Cabbage is one of the oldest cultivated vegetables, dating back over 2,500 years, and Westar represents modern breeding for consistency and flavor while honoring traditional cabbage-growing practices.
  • 🌱 A single mature Westar head can contain 20+ outer leaves folded around the central head, creating a natural protective structure that allows some storage without additional processing.
