Soil preparation

Remove weeds, rocks and trash, and work the top 8 to 10 inches of soil before planting. Work the soil only when it is dry enough not to stick to garden tools.



Use 2 to 3 pounds of fertilizer, such as 10-10-10, for every 100 square feet of garden area. Spread the fertilizer evenly over the soil and work it into the soil 3 to 4 inches deep. Rake the soil to smooth the surface.



Sweet corn is a warm-season crop and must be planted after the soil warms and there is no more danger of frost. If you have room, plant again when the first corn plants have three to five leaves. This usually takes 2 to 3 weeks. You will need 1 to 2 ounces of seed for every 100 feet of row. Do not use seed saved from last year’s sweet corn as these seeds will not grow a good crop. Sweet corn grows best when planted in several short rows instead of one long row. This makes it easier for the corn plants to pollinate, and good pollination is necessary for ears of corn to have plump, juicy kernels.




Requires moderate levels of water: approximately 1″ per week. Keep soil evenly moist but not soggy. This is particularly important in the early stages of growth as overwatering the seeds can cause damage and decrease your germination rates.


Pest & Disease Management

The European Corn Borer and the Corn Earworm are two insects that attack sweet corn. Corn borers usually occur twice, in mid-June to early July and again in mid-July to September. Corn earworms occur during this later time period. In small garden plantings, these pests may not occur in a given year, and they may not require management. For more information about integrated management of these pests, please see the publication Integrated Management of Sweet Corn Insects in New Hampshire. Biological and chemical control strategies should be based on the presence of the insects, which can be determined by trapping. For more information, see the publication Setting up Traps to Monitor Sweet Corn Insects in New Hampshire.

Sweet corn is generally free of serious diseases. Occasional a grayblack mass appears on the ears. It is caused by a fungal disease known as smut. The best control is to cut off the ear and dispose of it.



Corn is ready for harvest about 3 weeks after the tassel grows on top of the corn plant. Corn is ripe when juice from the kernels is milky white, the silk on the ears has turned dark brown, the kernels get large, chewy and pasty like dough. The best time to pick corn is in the early morning or evening when it is cool. To harvest the ears, hold the stalk below the ear and twist the tip of the ear toward the ground until it breaks off. Cook the corn right away, or store it in the refrigerator until mealtime. Corn loses flavor and nutrients quickly when left at high temperature. Watch the corn closely because the quality changes fast.




Yellow corn is a good source of the carotenoids lutein and zeaxanthin, which are good for eye health and help prevent the lens damage that leads to cataracts. Corn also has smaller amounts of vitamins B, E, and K, along with minerals like magnesium and potassium. When it comes to nutrients, color matters.



Corn is particularly high in lutein and zeaxanthin, two carotenoids that may prevent cataracts and age-related macular degeneration (AMD).

Dietary fiber intake has been linked to a lower risk of several diseases, including heart disease and some cancers. Even more, eating enough fiber promotes healthy digestion and may protect you against gut issues.

Research specifically focusing on corn intake and diabetes is limited, but studies suggest that low-carb diets are more effective at managing diabetes.
