Days To Maturity

Days To Maturity

Average number of days from seeding date to harvest, within a specific crop group. If a transplanted crop: average number of days from transplant date. Not sure if crop is direct-seeded or transplanted? Check the Growing Information box for details. If crop can be both direct-seeded or transplanted, days to maturity refers to direct seeding. Days to maturity for all flowers and herbs is calculated from seeding date.

Life Cycle

Plants can be Annuals (single growing season), Perennials (grow year after year), Tender Perennials (grow year after year in warmer climates; and in some cases when given special protection in colder climates), or Biennials (require two years to mature).

SCIENTIFIC NAME: Brassica oleracea
CULTURE: Collards prefer a fertile, well-drained soil high in organic matter with a pH range of 6.0–7.5. Consistent moisture will produce the best quality leaves. In the South, collards are best for fall, winter, and early spring harvests, to avoid the temperature extremes of midsummer—even though they will tolerate some measure of heat. Because collards are very cold tolerant, they also do well in the North, where their flavor is enhanced by frost and cold weather.
DIRECT SEEDING: Plant from early spring to approximately 3 months before expected fall frost. For bunching, sow 3–4 seeds every 12-18", ½" deep, in rows 18–36" apart. Thin to 1 plant per group. For baby leaf production, sow 60 seeds per foot in a 2–4" wide band ¼–½" deep.
EARLY SPRING CROP: Sow 2 seeds per cell in 50- to 72-cell plug flats, 3–4 seeds/in. in 20 row flats, or in outdoor beds ¼" deep. Seedlings should be ready to transplant in 4-6 weeks. If possible keep soil temperature over 75°F (24°C) until germination, then reduce air temperature to about 60°F (16°C). Transplant outdoors 12–18" apart in rows 18–36" apart. Collards prefer cooler growing temperatures, between 55–75°F (13–24°C), optimum being 60–70°F (16–21°C), but will produce good crops under warmer, summer conditions.
FALL CROP: Start seedlings as above in May and transplant to the garden in June–July. To ensure mature heads, seed the crop early in areas where heavy freezes occur early in fall.
WINTER CROP: Successful collards crops can be grown where winters are mild (temperatures rarely below 32°F (0°C)). Transplants can be set out from September to February in these regions.
DISEASES: Adhere strictly to a preventive program including: (1) long crop rotations with non-brassica crops, (2) clean starting mixes and outdoor seedbeds, and (3) strict sanitation practices. Johnny's Selected Seeds only sells seed lots of collards that have tested negative for black rot (Xanthomonas campestris pv. campestris) and black leg (Phoma lingam).
NOTE: A disease-free test result means that in the sample tested, the pathogen targeted was not found. It does not guarantee a seed lot to be disease-free. However, no method of seed treatment can positively insure freedom from disease. We are glad to help with specific questions.
INSECT PESTS: The best insect control is achieved with the use of fabric row covers applied at planting, to exclude insects from the plants.
HARVEST: Beginning about 2 months after planting, harvest by clipping individual leaves. Collards are very hardy, and the eating quality will improve into the late fall with light frost. Late summer sown or planted collards can be wintered in cold frames or hoophouses, or in the open in mild regions, to extend the season. Protecting with row covers can extend the harvest period.
DAYS TO MATURITY: From direct seeding; subtract about 14 days if transplanting.
AVG. DIRECT SEEDING RATE: For bunching: 1,000 seeds/220', 1 oz./1,110', 1 lb./24,000'.
TRANSPLANTS: Avg. 4,450 plants/oz.
SEED SPECS: SEEDS/LB.: Avg. 92,400.
PACKET: 100 seeds, sows 22'.
