(F1) Broccoli Seed

Product ID: 3756

The most cold-hardy variety for overwintering.

These sweet and tender, 6-8", bright-purple florets are a welcome addition to the market stand in February and March, when fresh greens are scarce. NOTE: Best adapted to the Pacific Northwest and Mid-Atlantic regions where winter temperatures are low enough to vernalize the plant but do not typically drop below 20°F/-7°C; Red Fire will winterkill in colder climates. Avg. 89,800 seeds/lb. Packet: 100 seeds.

Additional Information

CULTURE: Prefers a well-drained, fertile soil high in organic matter with a pH of 6.0-7.5.
Transplant (recommended): Sow in 72-cell plug flats 3–4 weeks before transplanting out. If possible keep soil temperature at 75–85°F/24–29°C until germination, then reduce air temperature to about 60°F/16°C to grow seedlings. Ensure good air circulation and light. Transplant out, spacing 18" between plants and 36" between rows.
Direct seed: Sow 3 seeds ½" deep, every 18" in rows 36" apart, thinning to 1 plant every 18" apart. Note: For fall harvested crops time sowing dates so that the crop will mature in early fall when the weather is cooling. For winter crops sow in late summer. Crops maturing in warm weather will be unpleasantly bitter.

The best insect pest control on young plants is the use of fabric row covers, which prevents the insects' access to the plants. Control flea beetles with azadirachtin or pyrethrin, cabbage worms with Bacillus thuringiensis. Prevent disease with crop rotation and good sanitation.

Harvest central head when mature and hydrocool or ice as soon as possible. Harvest secondary side shoots regularly to encourage continued production.

Seeds/oz.: Avg. 6,900. Transplants: Avg. 850 plants/1,000 seeds. Packet: 100 seeds, sows 50'
