Corn Seedlings Are Dying – What To Do With A Sickly Sweet Corn Seedling


By: Mary Ellen Ellis

Growing your own sweet corn is a real treat in the summer. But, if you can’t get your plants past the seedling stage, you’ll get no harvest. Diseases are not common in sweet corn grown in the garden, but there are some problems that can cause sickly sweet corn seedlings.

Problems with Sweet Corn Seedlings

If your corn seedlings are dying, they are probably suffering from a type of disease that particularly affects the seeds of the sweet corn plant. These diseases can kill the seedlings or affect them enough that the stands don’t grow well. They are caused by a few different types of fungus and sometimes by bacteria, and may or may not cause rot.

Diseased or rotting corn seedlings are more likely to simply die if they are planted in cold soil, but if planted in warmer soil, they may still sprout and grow. In this case, they will develop rot in the roots and at the stem near the soil line.

Preventing Sweet Corn Seedling Diseases

Prevention is always best, of course, and with corn seedlings two main factors that promote disease are the quality of the seeds and the soil temperature and moisture level. Low quality seeds, or seeds that are cracked or carrying a pathogen, are more likely to develop rot and disease. Cold soil temperatures, less than 55 degrees Fahrenheit (13 C.), and wet soil also promote disease and make seeds and seedlings more vulnerable.

Caring for seedlings of corn the right way will help prevent any rot or disease. Start by choosing high-quality seeds, even if you have to pay a little more. Seeds that have already been treated with fungicide will guarantee they are not carrying pathogens into your garden. Don’t plant your seeds until the soil temperature is above 55 degrees F. (13 C.). Using a raised bed can help raise the temperature.

You may also consider starting your seeds indoors and transplanting them outdoors when the weather cooperates, but transplanting corn is not easy. The plants don’t always respond well to being moved. If you try this, be sure to be gentle with it. Any damage to it can harm the plant.

Sweet corn seedling diseases are not common issues in the home garden, but it pays to take precautionary measures anyway and to give your seedlings the best chance of growing into big, healthy corn plants.

Sweet Corn Growing Tips

Corn Growing starts with deciding which type of corn to plant: standard, sugary, or supersweet.

Corn Growing starts with deciding which type of corn to plant: standard, sugar-enhanced, or super-sweet.

Standard sweet corn varieties (sometimes called “normal sugar”) have old-time “corny” flavor. ‘Golden Bantam’ is a classic yellow-kernel standard sweet corn, also ‘Country Gentleman’ (white kernels), ‘Silver Queen’ (white) and ‘Double Standard’ and ‘Honey and Cream’ (both bi-color kernels).

Sugar-enhanced corn cultivars are sweeter and tenderer than standard varieties. ‘Bodacious’, ‘Early Choice’, and ‘Kandy Korn’ are yellow kernel sugar-enhanced cultivars. ‘Platinum Lady’ and ‘Alpine’ have white kernels. ‘Gold ‘N Pearl’. ‘D’Artagnan’, and ‘Peaches and Cream’ are sugar-enhanced bi-colors.

Super-sweet corn cultivars are the sweetest of all but can lack flavor and tenderness. Yellow kernel super-sweet cultivars include ‘Illini Xtra-Sweet’ and ‘Krispy King.’ ‘How Sweet It Is’, ‘Sugarburst’, and ‘Aspen’ are white kernelled. ‘Honey ‘N Pearl’ and ‘Skyline’ are bicolor.

Here are a few tips to take into the corn growing season:

Temperature. Sow or plant corn directly in the garden two weeks after all danger of frost is past and the soil has warmed to 60°F. In cool regions and where cool weather persists, spread black plastic on the planting area to speed ground warming, or sow seed in sun-warmed ridges about 3 inches above the planting bed. Protect young seedlings from chilly nights with a floating row cover.

Indoor Seed Starting Corn. Corn can be started indoors in peat pods to avoid disturbing the roots at transplanting time. Seeds germinate at 50°F. Seedlings should go into the garden within a couple of weeks of emergence this is important to avoid a check in growth. Time indoor sowing so that corn goes into the garden when the outdoor temperatures are very warm corn loves heat.

Sowing Corn. Early in the season, sow corn seeds 1 inch deep after the weather has grown hot in mid-summer, sow corn 3 to 4 inches deep. Set seed 2 to 3 inches apart in rows space rows 30 to 36 inches apart. (Closer spacing will result in smaller ears at harvest.) Make successive sowings every 2 to 3 weeks for a continuous harvest summer into fall or plant early, midseason, and late varieties at the same time.

Thinning Corn. Thin corn seedlings 10 to 14 inches apart. Thin unwanted seedlings by cutting them off at soil level don’t pull up unwanted seedlings, you may disturb the roots of plants nearby.

Feeding Corn. Corn is a heavy feeder. Place a band of aged compost in a furrow two inches from where you are going to sow the seed and an inch deeper than seed level. Feed corn with a high-nitrogen fertilizer or side-dress with aged compost when stalks are 8 inches high and again when they are 18 to 24 inches high. Corn will grow particularly well where nitrogen-setting beans and legumes have grown the season before. The winter before planting corn, add aged manure and compost into the planting bed and work it into the soil with a garden fork.

Weeding. Corn is shallow rooted competing weeds can rob corn of nutrients and moisture. Keep weeds out of the corn patch especially during the first month of growth. After that, control weeds by applying thick mulch of compost. A cover crop of nitrogen-setting clover planted a month after corn is planted will also keep weeds down.

Corn Pollination. Corn is wind pollinated (and easily cross-pollinates). Planting corn in short blocks of 3 to 4 rows rather than a single row will aid wind pollination and increase yield. To avoid cross-pollination, plant different corn varieties at least 100 or more feet apart or plant so they tassel two weeks apart. (A corn stalk is topped by a flowering tassel that produces pollen. Wind carries the pollen to silky threads on the ears a quarter the way down the stalk. Each silk is connected to an unfertilized kernel. The number of kernels in an ear is the same as the number of silks that were pollinated.)

Lodging Corn. If maturing corn stalks begin to fall over (called “lodging”), simply straighten them up and pack some soil around the roots and crown of the plant. Hilling corn early in the season may prevent lodging: use a hoe to draw up soil around the stalks as they mature.

Corn Harvest. Harvest is near when ears are plump and silks have withered, about three weeks after the silks appear. To know when to pick corn–apart from ears being plump, pull back part of the husk and pierce a kernel with your thumbnail. If there a milky juice spurts out, the sweet corn is ripe. (If the juice is watery, the corn is immature. If the juice is pasty, the corn is past its prime.) Corn is at is peak of sweetness for two to five days.

Corn Yield. Corn will yield 1 to 2 ears per plant, about 10 to 12 ears per 10-foot row. Plant 10 to 15 plants per person.


A week or two before planting, remove all rocks and debris from the garden bed and work the upper 8 to 10 inches of soil. Plants require a fair amount of nutrients due to their quick vegetative growth, so incorporate 3 to 4 inches of organic matter — finished compost or well-aged manure — into the soil.

After the threat of spring frost is over, direct sow seeds into the recently prepped garden bed. Sow seeds approximately one-half to one inch deep, covering with soil. Space seeds 4 to 6 inches apart within rows, 30 to 36 inches between rows. After germination, thin seedlings to a spacing of about 12 inches between plants.
