Size

Packet, 1,000 Seeds, 5,000 Seeds, 25,000 Seeds

SCIENTIFIC NAME

Brassica oleracea

CULTURE

Kale prefers a fertile, well-drained soil high in organic matter with a pH range of 6.0–7.5. Consistent moisture will produce the highest-quality leaves. For baby-leaf production, see the Baby Leaf Brassica Greens culture.

DAYS TO MATURITY

From direct seeding; subtract about 14 days for days to maturity from transplant.

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.

EARLY SPRING CROP

Use varieties suited to warm-season production. 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. Kale prefers 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 kale crops can be grown where winters are mild and temperatures rarely fall 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 kale that have tested negative for black rot (Xanthomonas campestris pv. campestris) and black leg (Phoma lingam).

INSECT PESTS

Kale is not as afflicted with pests as are other brassica crops such as cabbage. Apply row covers at the time of planting to exclude pests from the crop. Control cabbage worms and loopers with Bacillus thuringiensis (Bt).

HARVEST

Beginning about 2 months after planting, harvest by clipping individual leaves. Kale is 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.

AVG. SEEDING RATE

For bunching: 1,000 seeds/220', 1 oz./1,110', 1 lb./24,000'.

TRANSPLANTS

Avg. 6,400 plants/oz.

SIZED SEEDS

"Sized" seeds have been sorted so they are roughly the same size. This consistency allows for more accurate spacing with mechanical seeders and more even germination. Kale seeds are sized, except when noted in the product description.

SEED SPECS

SEEDS/LB.: Avg. 124,000.

PACKET

100 seeds, sows 22'.
