How to Garden the Leaves on My Corn That Are Turning Yellow

Corn is a tall, bushy, summertime crop that takes up a lot of space, but gives sweet rewards to the careful gardener. Different cultivars offer white, yellow, and bicolored ears, with early-, mid- and late-season harvests. All corn cultivars require the right site, soil, water, and nutrition, and will fail without the correct growing conditions. Yellow corn leaves in mid season generally signify lack of nutrition or water. Amend the soil with both compost and fertilizer to heal the plants and continue with healthy growth and harvest.

Instructions

    • 1

      Amend the soil around the corn plants to increase long-term soil nutrition. Lay 3 inches of organic compost on top of the soil in a 10-inch circle around each plant, and turn it into the top 3 inches of natural soil. This amendment adds gentle, safe organic material with vitamins, minerals, and moisture retention.

      Fertilize the corn plants. Yellow leaves mean a lack of nitrogen and potassium in the soil. Apply a complete fertilizer like 12-12-12, or a nitrogen-heavy fertilizer like 10-5-5, according to manufacturer directions. Turn the fertilizer into the top 3 inches of soil.

      Water the corn after soil amendment and feeding to help the nutrients soak down to the roots. Give each corn stalk 2 to 3 inches of water. Sprinkle the water around the 10-inch circle you built with the compost, to hit all the amendments.
