Organic (F1) Cauliflower

Product ID: 3529G

Organic mid-season variety.

For summer or fall harvest. Heads are smooth, large and heavy, and hold well in the field. The big plants have excellent wrappers (in good soils), resulting in very white heads. Performs best in fall, but is suitable for summer harvests. Best for northern regions. USDA Certified Organic. Avg. 125,000 seeds/lb. Packet: 50 seeds.

SCIENTIFIC NAME: Brassica oleracea
CULTURE: Cauliflower prefers a well-drained, fertile soil high in organic matter, a pH of 6.0–7.5 with consistent moisture throughout the growing season. Irrigate regularly for best results. Cauliflower does not do well in hot weather; the best success is with spring and fall crops.
EARLY SPRING CROP: Use early and midseason varieties. Sow in 72-cell plug flats. Seedlings should be ready to transplant in 4–6 weeks. If possible, keep soil at least 70°F (21°C) until germination, and 60°F (16°C) thereafter. Transplant outdoors when seedlings are no older than 4–5 weeks old. Older plants tend to be stressed and do not perform as well as actively growing seedlings. Harden plants carefully by gradually increasing cold before transplanting out, 18" between plants and 24–36" between rows.
FALL CROP: Use midseason and storage varieties. 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 cauliflower 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.
DIRECT SEEDING: Sow 3–4 seeds 18" apart, ½" deep, rows 24–36" apart, thinning to one plant in each group.
DISEASES: Adhere strictly to a preventive program including: (1) long crop rotations with non-cruciferous crops, (2) clean starting mixes and outdoor seedbeds, and (3) strict sanitation practices. Black rot can be seed-borne. We only stock seed lots that have been tested free of black rot in a sample of 30,000 seeds. Individual seed lots have been tested free of black leg in a sample of 1,000 seeds.
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: Repel flea beetles and root maggots on young seedlings by covering with floating row covers from day of planting. Treat flea beetles with insecticides such as pyrethrin or azadirachtin if heavy pressure is observed. For cabbage worms and loopers, use bacillus thuringiensis (bt). cutworm prevention: cultivate soil 24 weeks before planting to work in cover crops and destroy weeds.
BLANCHING: Exposure to the sun can cause white cauliflower heads to yellow. To prevent yellowing and promote better head quality in hot weather, follow this blanching technique: at the moment when small white heads are just visible through leaves, gather the outer leaves over the head and tie with string or a large rubber band to preserve white curd color. Another method is to crack the leaf midribs and fold them over the heads until completely covered. Be sure not to break the leaves, or they may blow away. Tied or covered heads may experience increased humidity and greater likelihood of contracting alternaria. As such, practice blanching only when necessary; not in the cool, shorter days of fall, or with colored varieties that need sunlight to achieve their full color.
HARVEST: Keep an eye on development, cutting heads when desired size is obtained but before the curds becomes loose, or "ricey."
STORAGE: Store at 32°F (0°C) and 95–98% relative humidity for 2–3 weeks.
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. Cauliflower seeds are sized, except when noted in the product description.
SEED SPECS: SEEDS/LB.: 84,000-164,400 (Avg. 105,800).
PACKET: 100 seeds, unless otherwise noted.

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.

62 Days

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).

Annual

Hybrid Status

Hybrid: The offspring of a cross between two or more distinct parent lines, usually of same species, and selected for improved traits.
Open-pollinated: A non-hybrid variety that can reproduce itself in kind, demonstrating relatively stable traits from one generation to the next.
