| SCIENTIFIC NAME | Brassica oleracea |
| CULTURE | Kale prefers a fertile, well-drained soil high in organic matter with a pH range of 6.0โ7.5. 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 3โ4 seeds every 12โ18", ยฝ" deep, in rows 18โ36" 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, 3โ4 seeds/in. in 20-row flats; or, in outdoor beds ยผ" deep. Seedlings should be ready to transplant in 4โ6 weeks. If possible, keep soil temperature over 75ยฐF (24ยฐC) until germination, then reduce air temperature to about 60ยฐF (16ยฐC). Transplant outdoors 12โ18" apart in rows 18โ36" apart. Kale prefers cooler growing temperatures, between 55โ75ยฐF (13โ24ยฐC), optimum being 60โ70ยฐF (16โ21ยฐC), but will produce good crops under warmer, summer conditions. |
| FALL CROP | Start seedlings as above in May and transplant to the garden in JuneโJuly. 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 32ยฐF (0ยฐC). 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'. |
