Weed a sunny garden bed and rake out any debris or impediments. Till the soil to a depth of 12 inches and incorporate 5 inches of compost at the same time. Rake the bed to a smooth, even state.
Push the maize seeds into the soil 1 to 1 1/2 inches deep. Space the seeds 12 to 15 inches apart in multiple rows of 36 inches apart. Plant three seeds per area to ensure germination, and thin them to the largest after they sprout.
Water until the top 4 inches of soil are wet immediately after planting and as the seedlings grow. Keep the bed evenly moist to a depth of 12 inches once the plants are 2 feet high.
Side dress with a high nitrogen fertilizer like 12-8-8 after the plants are 12 to 18 inches tall. Provide 3 inches of organic mulch between the rows to minimize weeds.
Harvest the ears when the inside juices run milky. Snap off the ears as needed by twisting them off the stalk quickly.
