Corn performs best in soil that is well-drained, but also able to hold onto some moisture, as corn tends to use quite a bit of water during its active growth phase.  Working in a healthy dose of well-composted manure in the fall will ensure that the rapidly growing plants receive adequate water and nutrition. 

After danger of frost has passed and soil temps have reached 55 degrees, sow seeds 9-12" apart, 1" deep, in rows 24-36" apart.  To maximize pollination use a paired row or square plot configuration.  Under ideal conditions, germination will occur in 7-10 days.

Insect Pests

Biological controls such as Bacillus thuringiensis can be effecting in controlling common corn pests like corn borer and earworm.  Aphids, Japanese beetles, and other hard-shelled insects can be controlled with a simple homemade insecticidal soap solution.

Diseases & Other Problems

Corn is susceptible to a number of plant diseases.  Consult your local extension office to learn which diseases are most prevalent in your region. Crop rotation, tillage, and removal of plant debris are all effective tools in managing common corn diseases.

Sweet corn is ready to harvest approximately 21 days after pollination. At peak, the kernel tips should be rounded and glossy. Shelling corn can be harvested once the husks have dried and the kernels have sufficiently hardened.  To test for maturity, pull back the husk and remove a kernel from the ear.  If the tip at the base of the kernel breaks off to reveal a brown "abscission" layer, the ears are ready to harvest.

CONSIDERATIONS:

To maintain genetic diversity, save seed from at least 50 to 100 plants.  If open-pollinated, plants should be isolated from other corn varieties by at least 1/4 mile.  Otherwise, hand-pollination can be performed.

HARVESTING SEED:

Wait until ears have reached full maturity and the kernels cannot be pierced by your fingernail. Peel back the husk and harvest the ear by pulling down and twisting. Place in a mesh bag or basket and allow to continue to dry for two weeks. Shell ears using a manual corn shelling tool or tightly grip a gloved hand around the ear and twist to separate the kernels from the cob. Winnow to remove any chaff and store in an airtight container until ready to use.

SEED LONGETIVITY:

Corn seeds will maintain 50% viability for three years when stored in a cool, dark place.
