Feeding Sweet Corn

Answer 1

Unless you already know about your soil's health, I would have it tested. Fertilizing corn should be done on the basis of soil tests. Every type of soil is different and has a different chemical make up that requires different fertilizers. That being said, it is usually better to use manure or compost whenever possible; but in addition, fertilize with a commercial fertilizer such as 10-10-10. Corn should be lightly fertilized prior to planting. It should be fertilized again when the plants are approximately 4 inches tall and again when they are 8 to 10 inches tall. Approximately 1/4 pound of complete fertilizer for every 10 feet of garden row is sufficient in most areas. If you are not using manure, you may also want to consider side dressing with a nitrogen fertilizer 3 inches from plants once they reach about a foot tall.
