Grow It

Can I dry ears of Mirai sweet corn and plant the seeds?

How large is a mature ear of TGF Mirai Sweet Corn?

On average the ear is between 7 and 8 inches long and has 16 rows of kernals

How early can I plant TGF-Mirai Sweet Corn?

How do I grow TGF- Mirai Sweet Corn seed?

Corn seed, available at our Online Store, can be planted following instructions on our Grow Your Own Mirai Sweet Corn page.

Can I plant TGF-Mirai Sweet corn near other sweet corn varieties?

Isolate TGF-Mirai from other corn varieties to prevent cross-pollination which can change the sweetness and quality of the harvested ears.

How many days from planting to maturity?

On average 71 days depending on weather and soil conditions. When silk appears on the ear, it will be approximately 21-24 days until maturity which is key to the maximum sweetness.

Mirai will last 7 to 10 days in the refrigerator with the husks left on.

Is it really okay to eat the corn raw?

Absolutely — it’s delicious!

Do you have bi-color sweet corn?

We can’t guarantee that both yellow and bicolor sweet corn will be available every day. One day we have yellow, another day we have bicolor, and some days we have both. Most customers love both, but you may gladly call ahead to check.

How do I prepare Mirai sweet corn?

Remove husks and silk. Place the ears in enough boiling water to completely cover them, and boil for 2-1/2 to 3 minutes — avoid overcooking.

Remove husks and silk and rinse with water. Lightly wrap or cover ears with damp paper towels or napkins, and cook at full power for 2 minutes per ear. To ensure that the corn is evenly cooked, turn it once halfway through the cooking cycle.

Grilling (it’s delicious!)
For grilling, keep the husks on the ears of corn, but remove exposed silk and any long “flag leaves” that may be attached to the ears. Soak the ears in cold water for one hour — this allows the corn to steam on the grill for excellent flavor. After soaking, place the ears on a hot grill (don’t stack them). While cooking, rotate the ears 1/4 turn often, until husks are blackened and kernels have turned darker yellow.

Remove husk and silk. Blanch corn by placing ears in boiling water for 2 minutes. Remove the corn from the pot, cut kernels from cob. Package the corn immediately in freezer bags, and place in freezer.
