Hopi Blue Dent Corn (Heirloom 100 Days)
The Hopi Blue Dent Corn is a royal blue colored heirloom flint corn that can be eaten as sweet corn when picked young, ground into meal for tortillas and bread after being dried, or used ornamentally for fall decoration. Bushy, five foot tall stalks with 8 to 10 inch ears.
Germination: 7-14 days
Germination Temperature: Optimum soil temperatures 60-85ºF. Planting in soil under 60ºF results in poor germination.
Seed Sowing Depth: 1” deep
Sowing Outdoors: In late spring , after the last frost date , when soil reaches at least 60ºF. Sow 4-6” apart, thin to 10-12” apart. Plant in blocks, 4-5 rows, 24-36” apart to aid with pollination. Corn is pollinated by wind therefore planting in blocks ensures proper pollination rather than one long single row where the pollen can easily blow away resulting in small, poorly filled out ears.
How much does a packet plant: 30-40 foot single row, block of 5 rows at 8 foot.
Harvest: Ready for picking 2 1/2 - 3 weeks after silks appear. Silks become dry and brown. The kernels should be plump and full. Test by pressing your fingertip into a kernel, looking for a "milky" appearance. Best picked in the morning and refrigerate/cool right away.
Harvest Dent or Ornamental Corn: When husks become dried or after one or two frost.
Harvest Popcorn: When ears are mature, kernels appear shiny and are hard. Remove the husk and let the ears dry for a few weeks. Test pop kernels after a few weeks to see if they are dry enough. Store popcorn by removing kernels or leave them on the ears.
Tips: The Hopi Blue Dent Corn needs an abundance of nitrogen. Add manure (in the fall) or rich compost a few weeks before planting. Add a high-nitrogen organic fertilizer every few weeks until tassels form. Keep well weeded, especially when they are seedlings and well watered, 1 inch a week especially during the silk stage.
