Corn Popcorn Robust Pop 400MR Seeds

Corn Popcorn Robust Pop 400MR Seeds

Zea mays (hybrid)

Item #0297

95-100 days. Once only commercially available, this type of popping corn is now available to the home gardener! Robust Pop 400MR produces large, round popped kernels that are 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 Jacks® box. Grow popcorn in your backyard to make kettle corn, caramel corn, popcorn balls, or to top with melted chocolate or cheddar seasoning. Grow just like other corn varieties.

This packet sows two 9-foot rows.

Days to Emerge:
5-10 days

Seed Depth:
1"-1 1/2"

Seed Spacing:
A group of 2 seeds every 12"

Row Spacing:
2'-3'

Thinning:
When 4" tall, thin to 1 every 12"

When to sow outside: RECOMMENDED. 1 to 2 weeks after average last frost, and when soil temperature is at least 60°F.

When to start inside: Not recommended.

Special sowing instructions: Since pollination occurs by wind, corn should be sown in short, parallel rows or blocks.

Harvesting: Let the ears dry on the stalks. They are ready for harvest when the kernels 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 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 stripping off the kernels to store in an airtight container. To strip off cured kernels, twist the cobs back and forth to loosen them (gloves are recommended).
