Kale is of poor quality in hot weather so fall crops are usually best. Kale is planted in late March to early April, or late plantings are made at the end of June. Plant seed 1/2 to 1 inch deep with plants 8 to 15 inches apart in rows 18 to 24 inches apart. Thinnings may be used as greens. Kale may be started early indoors with 4 to 6 weeks needed to get a suitable transplant. If no other fertilizer was applied, use 3 to 4 pounds of 12-12- 12 per 100 feet of row. Sidedress one or two times during the season to keep plants growing.
The outer leaves may be cut and used to allow the center of the plant to continue to grow. The younger leaves are best for eating. Another method is to cut and use the whole plant. The flavor is improved by frost. The plant is not stored.
