Cauliflower is a cool season vegetable, easiest to grow for harvest in the late summer or fall. Its success often depends on a slow steady growth that is difficult to achieve in mid-summer. Cauliflower does best in humus-rich, moist soil. CULTURE: For early crops, start indoors 4-6 weeks before planting out. For fall crops, plant in early to mid summer. Transplant when soil is 50F/10C (early May). SOIL: Cauliflower will grow in many types of soil, as long as it is not depleted of organic matter. FERTILITY: Openpollinated varieties use twice as much nitrogen as hybrid varieties. Use moderate amounts of nitrogen, phosphorous, and potash. GERMINATION: 7-10 days at 70F/21. Do not allow seedlings to get old in packs as this causes them to button up. Only plant fresh stock. SPACING: Space rows 32” to 36” wide; 45cm/18” between plants. For blanched white heads, tie wrapper leaves together forming a dome as the head is beginning to form. Pick when head has completely formed.
