Sow in early spring as soon as the ground can be worked or in mid-summer. Plant seed 1/4" deep, 4" apart in rows 1-1/2' apart, or in wide-row beds or circular islands. Allow 1-2 weeks for germination. Thin to 1-2' apart. Kale is very hardy. Withstands frosts well, which serves to enhance its flavor. A packet sows a 30' row.
