Growing Non-GMO Rainbow Jewel Popcorn Corn Vegetable Seeds

While corn prefers to be directly sown, some have been able to grow it from a start. Start seeds indoors about four weeks prior to the expected transplant date or three weeks before the last frost date. Keep the soil warm until germination. The seeds will struggle to germinate in cold soil. Harden off the starts carefully, then transplant them outdoors. Plant these in blocks of at least four shorter rows rather than one long row; this encourages proper pollination between the cobs. Sow seeds in spring/summer after the last frost (60 degrees F minimum soil temperature).

Keep the soil moist. Fertilize if the plants look pale or have pale veins. For a continuous harvest, plant a new batch of seeds whenthe first planting peaks through the soil. Maintain a weed free area around the plants to avoid competition. Optionally, seed a ground cover over the bare ground to decrease weeds and retain soil moisture.

Rainbow Jewel Popcorn Corn in the Vegetable Garden

Rainbow Jewel Popcorn Corn plants are just as ornamental as they are useful. The delicious kernels can be popped for consumption, or the cobs can be enjoyed as a delightful spectacle. These tall plants work well in garden scenarios as backdrops, supports, or barriers as well.

Harvesting Rainbow Jewel Popcorn Corn

Rainbow Jewel Popcorn Corn cobs can be harvested once the husks have dried and turned brown. Grasp the cob in one hand and the stalk in the other, and then firmly twist the cob off the plant. It should break off the stalk easily.

About Rainbow Jewel Popcorn Corn Garden Seeds

Native Americans would companion plant squash, beans, and corn to utilize the height of the corn, the climbing power of the beans, and the sprawling habit of the squash, all in the same square footage.

This variety of corn has resistance to foreign pollen contamination from it’s parentage.

The Rainbow Jewel Popcorn variety took almost ten years to develop and is a relatively new seed on the market.

Remove the dried kernels from the cob and pop them in a large lidded pot over medium-low heat with salt and butter… Delicious!

As indicated in the growing instructions above, corn plants must be planted in blocks, not one or two long rows; this is because they pollinate each other via the wind. The closer the plants are together, the lower likelihood that there will be unpollinated and unusable cobs. Opt for squares of corn rather than rows in your garden planning!

Tips From Our Gardeners

"A lot of hobby gardeners worry about having to hand pollinate corn; this is usually not necessary. While hand pollination does guarantee a full crop of cobs, if the plants are arranged in blocks, the wind should do all that work for you!"
