Some varieties have different textures, starch-content, color, and of course flavor. While sweet corn is the type that is used for eating off the cob, other varieties are great for grounding into flour, for popping as popcorn, for feeding to animals, or even using as decoration. Learn to grow different corn varieties with these tips on growing corn.

To grow your regular sweet corn garden varieties you will need nitrogen-rich soil. Ideally, plant corn where beans or peas were grown the previous year - these vegetables will increase the soil's nitrogen content. If you haven't practiced vegetable crop rotation , you can still grow delicious corn. Add organic compost or aged manure and mix into the soil before planting.

This crop does require adequate space. Seeds can be planted 12 inches apart, but there should be about 36 inches in between each row. Plant two or three seeds together, thinning to the strongest plant. One thing to keep in mind when planting your corn is that this vegetable is wind-pollinated; one species can cross-pollinate with another. If planting more than one corn variety at once, be sure to keep sweeter varieties separate. Also, to promote desirable cross-pollination between each plant, form a block of properly spaced plants, rather than one long row.

Once the seeds are in the ground water the soil well. Plenty of water is important for germination, more so for sweeter varieties. Water well every couple days when there is no rain. Add fertilizer once the plants are one foot tall. Harvesting time varies with different corn varieties.
