How to Plant Organic Sweet Corn Seeds

Start your corn planting in spring when the ground thaws. Prepare the soil after the last frost, then wait a week or two for planting, to give the ground a chance to warm and dry. All corn requires a starting temperature of at least 60 degrees Fahrenheit.

Find a site that gets full sun for eight hours every day, and drains quickly after watering or rain. Choose a site that gives you 10 to 20 square feet for planting corn.

Amend the soil in the entire site to produce the deep, rich and well-worked foundation that corn needs. Check the labels on your soil amendments to ensure that you're using only animal- or plant-derived material for organic growing, then till 1 inch of quick-draining soil and 2 inches of organic compost into the top 6 inches of soil in your site. Break up any dirt clods you find.

Add 5 to 6 lb. organic fertilizer per 100 square feet of growing space. Mix the fertilizer into the top 6 inches of soil to increase the fertility available.

Plant organic sweet corn seeds 1 inch deep at every 8 to 10 inches, with rows spaced at 2 to 3 feet. Align your rows with the prevailing wind in your area to encourage wind pollination during the bloom.

Water the corn with 4 to 5 inches of water to moisten and settle the soil, then put it on a schedule of 2 inches of water a week. Lay out 2 to 3 inches of organic mulch in the plot to maintain soil moisture and discourage weed growth.
