Needs rich soil and should not be planted in succession with other crucifers. Heads develop best in cool weather; excessive dry and hot periods can cause small "button heads" to develop. Sunlight can cause heads to turn yellow, so some varieties need their leaves tied together to shade the curd. 50 plants per 100 feet. One packet = 500 mg = 115 seeds and sows 28 feet. 1 oz. = 5600-10600 seeds. CULTURE: Start transplants 8-10 weeks before first frost; keep temperature 50-70 degrees Fahrenheit for 5-7 weeks. Direct seed 1/4 inch deep, 3-4 seeds per foot in rows 24-30 inches apart. Thin plants to 18-24 inches apart. Deep bed spacing 15 inches. SEASON: Cool season. Direct seed from May- June. MIN. SOIL TEMP: 40 degrees Fahrenheit. GERMINATION: 3-10 days. SOIL: Rich, slightly acid pH 6.0-6.8. COMPANION PLANT: Aromatic herbs, potatoes, celery, beets, onions.
