Days to Maturity: Approximately 60-65 days from transplant (or direct sowing in some cases) to harvest when heads are firm and solid.
Sun Needs: Full sun with at least 6-8 hours of direct sunlight daily—essential for tight head formation, good size, and flavor development in Utah's sunny conditions.
Season Type: Cool-season crop; plant early spring (as soon as soil is workable, around 40°F+) or late summer for fall harvest—tolerates light frosts well but prefers moderate temperatures (50-75°F) to avoid bolting or loose heads.
Plant Habit & Support: Compact plants 12-18 inches tall and wide; no support needed—space 12-18 inches apart in rows 18-24 inches apart for proper head development and airflow.
Other Notes: Resistant to some yellows (fusarium wilt) in many strains; watch for cabbage worms, aphids, clubroot, or splitting from uneven moisture—organic mulch (like straw or compost) helps retain moisture and suppress weeds; harvest promptly when heads firm up, as it doesn't store long in the field like later varieties.
Best Planting Method: Transplant in early spring or late summer when soil is cool and workable. Space plants 12-18 inches apart in rows or beds; plant at the same depth as in the pot. Amend soil with compost for fertility and excellent drainage—raised beds are ideal in heavier or alkaline Utah soils to prevent rot and clubroot. Organic mulch (such as straw, compost, or grass clippings) around plants retains moisture, moderates soil temperature, and suppresses weeds.
Watering Needs: Maintain consistently moist soil (1-2 inches per week) without waterlogging—even moisture throughout growth prevents splitting, loose heads, or bitterness; drip irrigation or base watering keeps foliage dry in dry Utah conditions to reduce disease. Mulch helps during warmer spells; avoid letting soil dry out completely, especially during head formation, and containers (if used) dry faster so check frequently.
Fertilization Needs: Incorporate compost or balanced organic fertilizer at planting for nutrient-rich soil. Cabbage is a heavy feeder—side-dress with a nitrogen-rich option (like compost tea or fish emulsion) 3-4 weeks after transplanting to support leaf and head growth, and possibly again midway, but avoid excess late to prevent soft, pest-prone plants. Harvest when heads are firm and dense (cut at base with a sharp knife)—remove outer leaves if needed, and use promptly for best crispness and flavor since it's not a long-storage type.
