Sow indoors in flats or pots with good potting soil February – September. Transplant into the garden about 3-4 weeks after sprouting. In our area kale can grow through the winter without protection, and survives best when sown in June for this purpose. Alternatively, direct sow March – August.
Collect seeds from 10-50 plants when seedpods have dried down. Cut seedheads, place on tarp, and dance to free them. Collect seeds from pile, winnow to clean. Isolate from other Brassicas of the same species by ½ mile.
