Collards are a cool-weather crop. Start seed indoors 4 to 6 weeks before the last frost in spring. Sow seed outdoors when the soil can be worked in spring. Place transplants in the garden when they are 3 to 4 inches tall as early as 3 to 4 weeks before the last frost in spring. In most regions, collards can be planted in early spring and again in late summer for fall or winter harvest.
