How to Fertilize Sweet Corn

Overview

Sweet corn is a fast-growing vegetable that is usually low-maintenance when it comes to fertilizer. Fertilizer helps raise the level of nutrients in the soil to harbor a beneficial growing environment for corn. Corn enjoys a nitrogen-rich soil environment with enough phosphorus. Growing well-fertilized corn involves attention to preparing the bed for the corn seeds and a keen eye to watch for signs of nutrient deficiency during growth.

Step 1

Spread a 2-inch layer of compost over the area in which you will plant the corn.

Step 2

Lightly sprinkle organic nitrogen fertilizer over the layer of compost.

Step 3

Mix the compost and nitrogen fertilizer mix with the ground soil until the compost/soil mix is about 5 to 7 inches deep.

Step 4

Plant the corn according to planting instructions for your strain of corn.

Step 5

Fertilize the plants with a natural liquid corn fertilizer when the corn plants have reached a height of 4 inches. Fertilize the plants again when they are around 10 inches tall.
