✔Sow seeds indoors or outdoors 4 to 6 weeks before the last frost in spring or as soon as the soil can be worked.
✔Kale prefers rich, well-drained soil with a soil pH between 5.5 and 6.8. Plant kale in full sun; plant kale in partial shade in warm regions. For optimal flavor, grow kale in cool weather.
✔Kale is a cool-weather crop that can tolerate temperatures as low as 20°F (-6°C).
✔Planting and Spacing Kale Sow kale seed 0.5 inch (2 cm) deep spaced 3 inches (8 cm) apart; thin plants to 12 inches (30 cm) apart when they are 4 to 5 inches (10 cm) tall.
✔Keep kale well watered for sustained growth and to keep leaves from getting too tough.
✔Kale will be ready for harvest 70 to 80 days from seed. Cut individual leaves for use when the plant is 8 to 10 inches (20-25 cm) high; cut the outside leaves first.
✔If you harvest the entire plant, cut 2 inches (5 cm) above the soil and the plant will sprout new leaves in 1 to 2 weeks.
✔Harvest kale before it gets old and tough.
Good harvest!
