How to Grow Hopi Blue Corn Seeds:
Hopi Blue Corn is a traditional flour corn that needs warm soil, full sun, and enough space for good pollination. Direct sow outdoors after all frost danger has passed and soil is consistently warm (ideally above 16–18°C / 60–65°F). Choose a full-sun spot with well-drained soil and mix in compost if your soil is poor. Plant seeds about 2.5–4 cm (1–1.5 in) deep. Corn pollinates by wind, so plant in blocks instead of a single row—at least 4 short rows side-by-side. Space seeds 20–30 cm (8–12 in) apart in rows, with 60–90 cm (24–36 in) between rows. Keep soil evenly moist until germination, usually 7–10 days in warm conditions.
How to Care for Hopi Blue Corn:
Water deeply and regularly, especially when plants are knee-high, tasseling, and forming ears—drought at these stages reduces yield. Aim for steady moisture, not soggy soil; mulch helps hold water and suppress weeds. Corn is a heavy feeder, so side-dress with compost or a balanced fertilizer when plants are 20–30 cm tall and again when they start to tassel; avoid overdoing nitrogen late, which can delay ear fill. Hill soil lightly around the base when plants are 30–45 cm tall to support roots and keep stalks upright. Watch for pests like cutworms (seedling stage), corn earworms, and birds; netting or paper bagging ears can help if pests are heavy. Harvest timing depends on your goal: pick young ears for fresh eating when silks turn brown but kernels are still soft, or let ears fully mature and dry on the stalk for blue corn meal. For dry harvest, wait until husks are papery and kernels are hard, then cure ears in a dry, airy place before shelling.
