GROWING INSTRUCTIONS

Sow Sunglow Corn seeds directly in the garden after the last frost date, when soil temperatures reach at least 60°F. Space rows 36 inches apart and plant seeds 1.5 inches deep, 12 inches apart in rows.

Germination occurs within 7-10 days. Thin seedlings to maintain proper spacing. Corn is wind-pollinated, so plant in blocks rather than single rows to ensure good pollination. Harden off seedlings before transplanting if starting indoors.

Water regularly and fertilize every 10 days with a corn-specific fertilizer. Harvest when ears are full and kernels are plump. Enjoy fresh, grilled, or boiled for the best flavor.
