Botanical Name: Brassica oleracea var. italica (hybrid)
Days to Maturity: 65–70 Days
Hardiness: Frost-tolerant annual
Plant Dimensions: About 18" wide, 20" wide
Variety Information: 6"–8" blue-green, domed heads are tightly packed with medium-sized florets and followed by smaller florets. Widely adapted.
When to Sow Outside: 4 to 6 weeks before your average last frost date, or when soil temperature is at least 40°F, ideally 60°â€"85°F. Also in late summer for fall harvest. Mild Climates: Best sown in fall or winter for cool–season harvest.
When to Start Inside: RECOMMENDED. 4 to 6 weeks before our average last frost date. Transplant 1 to 2 weeks before your average last frost date.
Days to Emerge: 7 – 14 days
Seed Depth: &?#8539;"
Seed Spacing: A group of 3 seeds every 24"
Row Spacing: 24"–36"
Thinning: When 2" tall, thin to 1 every 24"
Special Instructions: Keep area weeded, especially when plants are young and have shallow roots. To guarantee good pollination, gently shake the tassels to release the pollen onto the silks. You can also hand pollinate by pulling off a tassel from one plant and wiping it on the silks of several ears. If you notice "skips" or blank spaces on an ear where a kernel should be, that is an indication of inadequate pollination.
Special Care: Corn is pollinated by wind, so to get the best pollination and ""kernel fill"" (each silk when pollinated becomes a kernel), sow corn in parallel rows or blocks rather than one long row. Cross-Pollination: Sweet corn will cross-pollinate with other sweet corns, field corn, and popcorn, which results in poor eating-quality corn. To minimize cross-pollination, stagger sowings of different corn varieties so they mature at least 14 days apart. It's important to note that even corn that is grown in a nearby garden or farm can cross-pollinate with yours. To grow corn using the traditional "3 Sisters" Native American method, sow 4â€"5 seeds in 18"" circles, 4' apart. When the plants reach 1'â€"2', mound the soil up around them in a hill. Then sow pole beans at the base to grow up the stalks and provide nitrogen for the corn. Grow squash around them to shade the roots, conserve moisture, and control weeds."
Harvesting: When the main head gets to 6"-8" in diameter and florets are enlarged but are still closed, harvest the head. This will encourage large numbers of side florets.
