Germinating kale seeds
Sow your kale seeds directly into the garden as soon as the soil is dry and can be worked, or about four to six weeks prior to the last expected frost date. They'll germinate best if the soil has reached temperatures between 60 and 65 degrees Fahrenheit. Plant them 1/2 inch deep and 3 inches apart, with about 18 to 24 inches between rows. Your kale seeds will germinate in five to 10 days, and you can expect to harvest your crop in 50 to 75 days.
