Indian Corn Growing Techniques

Planting

• Ornamental corns can be grown in any area where other corn crops such as sweet corn or popcorn are grown. Plant approximately 20,000 seeds per acre, with one seed every 4 inches in rows spaced about 2 feet apart for garden-type growing operations. To prevent cross-pollination, plant ornamental corn at least 250 feet from other corn types. Plant ornamental corn no later than May 25 for harvest in the middle of September.

Pests

• The same pests that plague other corn types can be a problem for ornamental corn. Deer, raccoons and birds can cause crop loss. Corn borers and Japanese and flea beetles are also an issue. Insecticides and herbicides for weed control are commonly used in commercial operations. Electric fences are the most commonly used methods to control deer and raccoon damage, while bird repellents such as scarecrows, inflatable snakes and noise makers are used to combat bird depredation.

Harvest

• Ornamental corn is harvested by hand. Break the ear free of the stalk by twisting it down while leaving the husk attached. Allow the ear to dry about one more week before removing the husk for storage.

Moisture and Fertilizer

• Ornamental corn is commonly grown as a dryland corn, meaning it's grown without irrigation. Supplement rain, if possible, with watering if the corn shows signs of stress such as curled leaves. Corn in general requires approximately 1 inch of moisture per week, although after teaseling the requirement may double. Apply nitrogen at a rate of about 60 lbs. per acre for a yield of approximately 80 bushels per acre on soil containing about 50 tons per acre of organic matter. Increase the nitrogen for higher yields or if the soil contains less organic matter. Reduce the nitrogen in fields or gardens with high organic content.
