Product Details
Once only commercially available, this type of popping corn is now available to the home gardener! 'Robust Pop R400MR' produces large, round popped kernels sturdy enough to hold a coating and stay in one piece, unlike the more common 'butterfly'-shaped popcorn. This is also the type of popcorn found in the popular Cracker JacksĀ®. Grow it in your backyard to make kettle corn, caramel corn, popcorn balls, or to top with seasonings.

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 13Ā½ā14%.) 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).
