If you planted corn stalks in your garden this year, you may not have any ears\nof corn growing on the plants just yet. In that case, you may be\nwondering when your corn stalks will produce ears of corn, and if there is\nanything you should do to help them along.\n\n\n\nSo, when does corn produce ears? A\ncorn stalk produces ears between July and October when planted in late spring\nor early summer. When you grow corn from\nseed, it will take 58 to 92 days to produce mature ears of corn. If you transplant corn seedlings into the\ngarden, it will only take 30 to 71 days to produce ears of corn.\n\n\n\nOf course, depending on the variety of corn that you choose, it may take a\nlonger time for your plant to begin producing ears. Other factors such as\nover fertilization, lack of pollination, or other environmental conditions can\nall delay the growth of ears on your corn stalks.\n\n\n\nLet\u2019s take a closer look at corn, when it produces ears, and the factors\nthat can affect your harvest.\n\n\n\nWhen Does Corn Produce Ears?\n\n\n\nA corn stalk will produce ears for harvest 58 to 92 days\nafter planting from seed, depending on growing temperatures. It is recommended to plant corn no earlier\nthan the last spring frost date.\n\n\n\nA corn stalk will produce ears 58 to 92 days (2 to 3 months) after planting from seed.\n\n\n\nTo check the frost dates in your area, check out this frost date calculator from the Old Farmer\u2019s Almanac.\n\n\n\nUsually, you will plant corn in May, June, or July and\nharvest 2 to 3 months later in July, August, or September. For example, sweet corn can be ready for\nharvest by July 4 in Pennsylvania.\n\n\n\nFor more information, check out this article on sweet corn production from the Penn State University Extension.\n\n\n\nOf course, different climates can produce corn at different\ntimes of the year. For example, Florida\nproduces 80% of winter (January to June) corn harvest.\n\n\n\nThe Northeast produces most of summer\/fall production for\nfresh market. Upper Midwest (Minnesota,\nWisconsin) and Northwest (Oregon, Washington) produce most of the corn used for\nprocessing.\n\n\n\nFor more information, check out this article on corn from the Purdue University Extension.\n\n\n\nYou can also plant corn seeds indoors in April or May to get\nahead of a short growing season. The\nseeds will germinate in 10 days, and you should transplant the corn seedlings\nto your garden 3 weeks later.\n\n\n\nFor more information, check out this article from Michigan State University on how to grow sweet corn. \n\n\n\nCorn stalks can grow 4 to 10 feet in height at maturity. For more information, check out my article on how tall corn grows.\n\n\n\nSweet corn requires 5 days for pollination after the first\nsilk strands appear. A mature ear of\ncorn will be ready 20 days after the first silk strands appear. Remember that the ears will mature faster in\nhot weather.\n\n\n\nAn ear of corn is ready for harvest 20 days after the silk first appears.\n\n\n\nThe sugar in corn will quickly turn to starch after it\nmatures, making it less enjoyable for eating. \nSo, be sure to mark the date on your calendar when silk strands first\nappear on your corn. Then, mark the day\n3 weeks later as your harvest date!\n\n\n\nHarvest corn early in the morning, when it is cool. Cook and use the corn immediately to prevent\nthe sugar from turning to starch.\n\n\n\nHow Many Ears Does One Corn Plant Produce?\n\n\n\nTypically, a corn plant will produce one or two ears of\ncorn. Early maturing sweet corn will\noften only produce one ear of corn.\n\n\n\nMost corn stalks will produce only 1 or 2 ears of corn.\n\n\n\nSweet corn that matures later will have two harvestable\nears. The second ear is usually smaller\nand develops later than the first ear.\n\n\n\nField corn, (used for corn oil, silage, and corn flakes,\namong other things) yields one to two ears per plant. This corn has lots of starch but no sugar, so\neating quality is poor.\n\n\n\nAn ear of corn usually weighs 8 ounces (half a pound), with\na length of 5 to 9 inches. An average\near of corn has 400 to 600 kernels in 12 to 20 rows.\n\n\n\nFor more information, check out this article on corn from the Iowa State University Extension.\n\n\n\nOne corn stalk can yield multiple ears of corn if space,\nwater, and nutrients are not limited. \nFor example, baby corn (small ears often used in stir-fry) can produce 6\nto 10 ears per plant.\n\n\n\nFor more information, check out this article on corn from Utah State University.\n\n\n\nDo Corn Stalks Keep Producing After Harvest?\n\n\n\nNo, corn stalks do not keep producing after harvest. Most corn stalks will yield 1 or 2 ears of\ncorn, and then they are done for the season.\n\n\n\nWhat Kind Of Corn Should I Plant?\n\n\n\nYou have some decisions to make when deciding which corn varieties to\ngrow. First, you will need to decide on the sweetness of the ears of corn\nyou will get at harvest time. You will\nalso need to decide how long you want to wait to harvest your corn.\n\n\n\nThe kernels on an ear of corn can be yellow, white, red, and other colors!\n\n\n\nSome corn stalks can produce ears up to 9 inches in length. Others\nproduce kernels with white, yellow, or red kernels.\n\n\n\nHere are some different varieties of corn you can try.\n\n\n\nGolden Bantam Corn \u2013 this corn stalk produces 5 to 6 inch ears with yellow kernels. Matures in 80 days and reaches a height of 5 feet and a spread of 12 inches. Sprouts in cool weather and often bears two ears per stalk.

Matures in 75 days and reaches a height of 7 feet and a spread of 12 inches. For more information, check out Ruby Queen Hybrid Corn on the Burpee website.\n\n\n\nDoes Corn Need To Be Pollinated?\n\n\n\nYes, corn does need to be pollinated. However, the wind handles pollination of\ncorn.\n\n\n\nFor this reason, you should plant your corn in \u201cblocks\u201d, or\nmultiple rows and columns. This allows\ncorn plants to pollinate each other during tasseling.\n\n\n\nPlant corn in blocks to allow the stalks to pollinate each other by the wind.\n\n\n\nFor more information, check out this article on corn from Texas A&M University.\n\n\n\nCorn stalks are monoecious, meaning that they contain both\nmale and female flowers on the same plant. \nIn fact, these male and female flowers both develop from the same \u201cperfect\u201d\nflowers.\n\n\n\nThe ear is the female flower of a corn plant, and the tassel\n(green, purple, or yellow stigma at the top of the plant) is the male flower.\n\n\n\nRemember that dry soil can delay silk emergence and prevent\nproper pollination, which can affect the production of kernels on ears of corn. This is because each silk strand connects to\none potential corn kernel (ovule).\n\n\n\nWhat Other Factors Affect Corn on Plants?\n\n\n\nThe quality of care that you give your corn will help to\ndetermine how good of a harvest you get each year. Remember that corn needs full sunlight,\nmeaning exposure to 6 to 10 hours of sun per day.\n\n\n\nOther important factors for corn growth are temperature, watering, fertilizing,\nand spacing.\n\n\n\nTemperature For Corn Stalks\n\n\n\nSoil temperatures should be at least 55 degrees Fahrenheit\n(13 degrees Celsius) for germination of standard sweet corn. For super sweet corn (containing up to 40%\nmore sugar than sweet corn), soil temperatures should be at least 65 degrees\nFahrenheit (18 degrees Celsius).\n\n\n\nFor more information, check out this article on corn from the University of Illinois Extension.\n\n\n\nOptimal growth for corn will occur when temperatures are between\n75 and 86 degrees Fahrenheit (24 and 30 degrees Celsius). Corn will not grow when temperatures are\nbelow 50 degrees Fahrenheit (10 degrees Celsius).\n\n\n\nFor more information, check out this article on corn from the Purdue University Extension.\n\n\n\nWatering For Corn Stalks\n\n\n\nCorn stalks have extensive root systems, so they can handle some drought\nstress. However, it is still important to avoid letting the soil dry out\ntoo much when growing corn.\n\n\n\nIf you find that you have a problem with dry soil, check out my article on how to treat dry soil.\n\n\n\nOn the other hand, over watering your corn plants can lead to root rot and\neventual death. \n\n\n\nBe careful not to over water or under water your corn stalks!\n\n\n\nThe best way to decide when to water is to feel the soil with your\nfingers. If the soil feels dry 2 or 3 inches below the surface, then go\nahead and water.\n\n\n\nFor more information, check out my article on over watering your plants.\n\n\n\nTry to water early in the morning, rather than at night, to allow water to\nsoak into the soil. Avoid getting the leaves wet to prevent rot, mold,\nand diseases.\n\n\n\nFertilizing For Corn Stalks\n\n\n\nBefore you sow corn seeds or put transplants in your garden, add some\ncompost to your soil. It will provide organic material and nutrients for\nyour plants as they grow. The best part is that you can make compost\nyourself from ordinary yard and kitchen waste!\n\n\n\nCompost is a way to recycle yard and kitchen waste while providing nutrients and organic material for your garden soil.\n\n\n\nFor more information, check out my article on how to make compost.\n\n\n\nIt may be necessary to use fertilizers as a supplement to compost, in order\nto provide extra nutrients if your soil is lacking. The best way to tell if you\nneed fertilizer is with a soil test.\n\n\n\nFor more information, check out my article on soil testing.\n\n\n\nA soil test will also tell you the pH levels in your soil, which should be\n5.8 to 6.6 for growing corn.\n\n\n\nAlthough corn does need lots of nitrogen for growth, remember that it is\npossible to harm or kill your corn stalks by over fertilizing them.\n\n\n\nFor more information, check out my article on over fertilizing and my article on low-nitrogen fertilizers.\n\n\n\nSpacing For Corn Stalks\n\n\n\nFinally, make sure to leave enough space between corn stalks\nto allow for proper growth! Otherwise,\nyour corn stalks will compete with one another for water and nutrients in the soil.\n\n\n\nSpace your corn stalks a foot apart to give them enough room to grow, and to avoid competition for resources such as water and nutrients in the soil.\n\n\n\nFor best results, plant your corn stalks 1 foot apart, with\n30 to 36 inches between rows. Any closer\nthan this, and you may get small ears or no ears on the corn stalks.\n\n\n\nAs an added bonus, this space makes it easier to water,\nfertilizer, and harvest your corn.\n\n\n\nConclusion\n\n\n\nBy now, you have a much better idea of when your corn stalk will produce ears. \nYou also know a bit more about how to take care of corn stalks and how to avoid\nthe problems that can affect your harvest.\n\n\n\nI hope you found this article helpful \u2013 if so, please share it with someone\nwho can use the information.
