Growing Info
Harvesting: Let the ears dry on the stalks. The kernels are ready for harvest when they are hard and you can no longer leave a mark on them with your fingernail. Before the first fall frost, give each ear a twist until it breaks off. Peel back the husks, then hang the ears in a cool, dark, dry place for 4 to 6 weeks to cure. This is important to prevent mold and to dry to the optimal moisture percentage for popping. (In a perfect popcorn world, that would be 13½–14%.) After that, the cobs are ready for popping or storing. To strip off cured kernels, twist the cobs back and forth to loosen them (gloves are recommended).
