  Normal Sugary (SU) – Isolate from field corn, popcorn, ornamental corn, and supersweets.

Germination / Soil Temp. - 55 to 60 degrees or warmer.
Shelf life – Not long at all, eat right away.

Sugary Enhanced (SE) – Isolate from field corn, popcorn, ornamental, supersweets & all SU types
Germination / Soil Temp. – Varies with variety.
Shelf life – A day or two.

Standard Supersweet (SH2) – Isolate from all other genetic types.
Germination / Soil Temp. – Finicky; best at 65 degrees or higher.
Shelf life – Several Days.

Augmented Supersweet (SE+SH2) – Can mix w/ other supersweets, but isolate from genetic types
Germination / Soil Temp. – Finicky; best at 65 degrees or higher.
Shelf life – Several Days.

Synergistic Enhanced (any combo of SU, SE, or SH2) – Isolate from field corn, popcorn, ornamental corn, supersweets, and SU types.
Germination / Soil Temp. – Varies with variety.
Shelf life – Several Days.

Soil Temperature - Wait until soil is moist and warm (65 degrees or higher). Another option is to plant under a clear plastic row cover to trap in solar heat.

How & Where to Plant – Your corn patch should be square or rectangular. Plant approx. 8”apart in rows 3 feet apart. (Check recommendations on seed pack).
Isolate varieties from other corn genetic types by at least 250 feet, or time plantings a few weeks apart so it tassels at different times. This will keep corn from cross pollinating. Also, you may choose early and late varieties to avoid overlap.

Fertilize and Water – Fertilize with 10-10-10 (or similar) right after seeds sprout. Fertilize again when stalks are tasseling. Use about 2 cups per 25 feet of row. Water especially from the time silks are forming until about 2 weeks after they turn brown. This is a crucial time when kernels form and fill out.
