Tender, blue-green leaves that will withstand light frost. The mild cabbage-like flavor actually improves with a light frost. Plant in spring and again in late summer for a fall to winter harvest. Avoid areas where any of the cabbage family members were grown the previous year.
Sow collards seeds in average soil in early spring; midsummer for fall crop. In frost-free areas, Sow from fall to early spring. In rows 36" apart, plant seeds evenly and thinly and cover with 1/4" of fine soil. Firm lightly. Collards plants emerge in 10-21 days.
How to Grow
Thin to 18" apart when seedlings are 1-2" high. To acclimate seedlings outside, "harden off" by moving them to a secluded, shady are for one week prior to transplanting. Transplant hardened-off seedlings 6-8" apart after all danger of heavy frost. Provide plants with 1-1 1/2" of water weekly. Do not plant cabbage family crops in the same place 2 years in a row.
Harvest whole plants at 6-8" tall, about 60 days after transplanting. You can also pick the bottom leaves of your collards as desired; the inner buds will continue to grow foliage. When harvesting fall crops, wait until a light frost comes if you prefer a sweet flavor for your collards.
