There are several varieties of sweet corn, some white, some yellow and some that combine both colors. Growing sweet corn in Kentucky is no different from growing sweet corn anywhere else. Corn is grown in every county in the state, according to the University of Kentucky. It grows best in deep, rich soil that is easy to work by hand. However, any soil that drains well is suitable for corn cultivation in Kentucky.
Turn over the soil to a depth of 6 inches.
Add 1 to 2 inches of compost to the soil and break it up with a shovel and hoe.
Mound the soil in rows 2 to 3 feet apart after the soil temperature reaches more than 50 degrees F.
Poke a hole about 1/2 inch deep with a finger. Place three or four seeds in the hole and cover them. Continue spacing the seeds between 8 and 12 inches for the length of the rows.
Keep the soil moist until the seeds germinate. Give the corn 1 to 2 inches of water per week once it has germinated. Water the corn if the soil feels dry 1/4 of an inch deep.
Thin the weaker plants when the corn reaches about 1 foot tall to encourage growth of the strongest plants. Add 1 to 2 inches of mulch around the plants to discourage weed growth and help the soil retain moisture.
