Grow Guide
CULTURE:
Broccoli prefers a well-drained, fertile soil that is high in organic matter with a pH of 6.0–7.5. A consistent supply of moisture throughout the growing season is important; irrigate regularly for best results. While more heat-tolerant varieties are now on the market, broccoli does not generally do well in hot weather. The best success is with spring and fall crops.
EARLY SPRING CROP:
Use early and midseason varieties. Sow 2 seeds per cell in 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 3–4 weeks. If possible keep soil temperature 75–80°F (24–27°C) until germination, then reduce air temperature to about 60°F (16°C). Ensure good air circulation and light. Transplant outdoors 10–18″ apart in rows 18–36″ apart. Broccoli 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.
