If you plan on growing heirloom corn this year, it is important to understand the different types of corn and how they are used. Are you looking for a "corn on the cob" type (sweet corn) or are you looking for one to make cornmeal? How about animal feed?

Growing Corn: usually germinates in 10-14 days.  Keep soil moist but not standing water.  Seeds can rot if they are left in soggy conditions.

Corn is wind-pollinated, so it should be planted in blocks, rather than in single row

Plant seeds outdoors approximately two weeks after the last spring frost date.

It’s important to get corn planted as soon as possible, since it requires a fairly long growing period with warm weather.

Plant seeds 1.5 to 2 inches deep and 4 to 6 inches apart.

Corn is considered a heavy feeder so plan to fertilize as soon as seeds sprout (2 inches tall) and plant in nutrient-rich soil.
