How to Fertilize Silver King Corn


Why buy corn in the grocery store when you can raise your own corn harvest at home? The Silver King corn variety comprises one of many choices available to backyard gardeners. It has exceptionally sweet white kernels, and is known as a sugar-enhanced variety, according to Iowa State University. Like all sweet corn varieties, Silver King corn has a high nutrient need to sustain its fast growth and ensure plump, juicy corn ears.

Step 1

Prepare the gardening area before planting the Silver King corn seeds. Use a spade and breakup the soil to a depth of 6 inches, then mix in 3 to 4 inches of compost. This improves the soil condition, adds nutrients, increases drainage, boosts aeration and helps the dirt retain moisture for a more hydrated corn crop.

Step 2

Apply fertilizer immediately before sowing the Silver King corn seeds. Purdue University recommends spreading 2 lbs. of 12-12-12 all-purpose fertilizer for every 50 square feet of gardening space.

Step 3

Fertilize the Silver King corn again once it's 8 to 12 inches tall. Apply the amount of 12-12-12 fertilizer as used in Step 2, spreading it in an even strip alongside each row of corn.

Step 4

Water the Silver King corn rows after fertilizing to help carry the fertilizer down to the plants' root level for immediate feeding.
