Broccoli Rabe (Raab) - Key Growing Information
CULTURE: Tolerates light frost and likes a soil pH of 6.0–7.5. Direct sowing is recommended: plant ¼–½" deep, 1–2" apart, in rows 18–24" apart, and thin to 4–6". For transplants, sow anytime from early spring to late summer, 2–3 seeds per cell in 72-cell plug trays, thinning to one, 3–4 weeks before planting out. If possible, keep the soil above 75°F/24°C until seedlings emerge, then grow them on at about 60°F/16°C air temperature with good light and airflow. Set plants 6–12" apart.
DISEASES AND PESTS: Fabric row cover is the most effective protection for young plants because it physically keeps insects off. Azadirachtin or pyrethrin controls flea beetles, and Bt controls cabbage worms. Rotation and good sanitation prevent most disease. See product pages for more detail.
HARVEST: Pick young leaves, stems and buds regularly for a harvest that lasts 2–4 weeks.
SEED SPECS: About 15,450 seeds per oz. Direct seeding rate: about 1 oz. per 1,000'; 1,000 seeds per 166'; 5,000 seeds per 830'; 175,000 seeds per acre at 6 seeds per foot in rows 18" apart. Packet: 250 seeds, enough for about 20'.
