The other day, I was reading about different varieties of\ncorn in online seed catalogs. I started\nto wonder how tall corn could get, so I did some research to find out.\n\n\n\nSo, how tall does corn grow? \nDepending on the variety, most\ncorn plants will grow to a height of 4 to 10 feet (1.2 to 3.0 meters) tall,\nalthough some varieties may grow even taller. \nHowever, environmental conditions such as temperature, soil quality,\nwatering, and competition can all affect the height of corn.\n\n\n\nDepending on your needs, you can choose corn varieties that\ngrow taller (8 to 10 feet) or shorter (4-5 feet). We\u2019ll look at some different corn varieties\nand their height, ear size, and time to maturity. We\u2019ll also look at how to ensure that your\ncorn grows to full height at maturity.\n\n\n\nHow Tall Does Corn Grow?\n\n\n\nAs mentioned before, the maximum height of corn can vary\ngreatly by variety, ranging from 4 feet to 10 feet or more. The shorter varieties only grow to a height\nof 4 to 5 feet, while medium height varieties grow 6 to 7 feet tall, with the\ntallest varieties growing to a height of 8 to 10 feet. Here are some varieties, arranged in order of\nincreasing height.\n\n\n\nEarly Sunglow Hybrid \u2013 this corn can start early, since it does well in cooler weather.\u00a0 This makes it ideal for short growing seasons.\u00a0 The plant reaches a height of 4 feet, with ears that are 7 inches long.\u00a0 At 63 days to maturity, this corn is ready in only 2 months.\u00a0 For more information, check out Early Sunglow Hybrid on Burpee\u2019s website.Baby Corn \u2013 this corn is great if you love baby corn for stir fries.\u00a0 These plants only grow to a height of 4 to 5 feet, with ears that are just 3 to 4 inches long.\u00a0 At 30 to 35 days to maturity, you will have baby corn ready just a month after planting!\u00a0 For more information, check out Baby Corn on Burpee\u2019s website.Golden Bantam \u2013 this heirloom variety is another early starter, which can do well in cool weather.\u00a0 The plant grows to a height of 5 feet, with ears of corn that are 5 to 6 inches long.\u00a0 At 80 days to maturity, it will take a few months from planting to harvest mature ears.\u00a0 For more information, check out Golden Bantam on Burpee\u2019s website.Sugar Buns \u2013 this early sweet corn matures quickly, making it another ideal choice for short growing seasons.\u00a0 The plant grows to a height of 5 feet, with ears of corn that are 7 inches long.\u00a0 At 60 days to maturity, it is one of the fastest-to-maturity varieties of corn.\u00a0 For more information, check out Sugar Buns on the Bonnie Plants website.Silver Queen \u2013 this variety yields large ears of corn with white kernels.\u00a0 The plant grows to a height of 5 feet, with ears of corn that are 8 to 9 inches long.\u00a0 At 92 days to maturity, you will have to wait a few months after planting to harvest mature ears of corn.\u00a0 For more information, check out Silver Queen on the Bonnie Plants website.Peaches & Cream \u2013 the name says it all: this corn yields ears that have both yellow (peaches) and white (cream) kernels.\u00a0 The plants grow to a height of 6 feet tall, with ears that are 8.5 inches long.\u00a0 At 70 days to maturity, the corn will be ready to harvest at just a little over two months after planting.\u00a0 For more information, check out Peaches & Cream on the Bonnie Plants website.Picasso Hybrid \u2013 the stalks and husks of this corn variety are deep purple.\u00a0 The plants grow to a height of 6 to 7 feet, with ears of corn that are 7 to 8 inches long.\u00a0 At 75 days to maturity, you will only need to wait 2.5 months after planting to harvest mature ears of corn.\u00a0 For more information, check out Picasso Hybrid on the Burpee website.Ruby Queen Hybrid \u2013 the kernels of this corn variety are red and sweet.\u00a0 The plants grow to a height of 7 feet, with ears of corn that are 8 inches long.\u00a0 At 75 days to maturity, you only have to wait 2.5 months before you can harvest mature ears of this unusual corn with red kernels.\u00a0 For more information, check out Ruby Queen Hybrid on the Burpee website.Glass Gem Ornamental \u2013 the kernels of this corn variety take on just about any color you can imagine, and they look like tiny gemstones!\u00a0 This tall corn variety grows to a height of 8 to 10 feet, with ears of corn that are 6 to 8 inches long.\u00a0 At 110 days to maturity, this variety is the slowest to mature on our list \u2013 you will wait almost 4 months from planting to harvest mature ears of corn. For more information, check out Glass Gem Ornamental on the Burpee website.\n\n\n\nAs you can see, most corn takes 2 to 4 months to reach full\nmaturity, so if your plants aren\u2019t as tall as you hoped for after a month or\nso, give them more time. Of course,\nthere are some things you can do to make sure that you are providing your corn\nwith everything it needs to grow as tall as possible.\n\n\n\nThere are some steps you can take to get your corn to grow bigger - more on this below.\n\n\n\nHow To Grow Big Corn\n\n\n\nVarious environmental factors can affect the height and\nhealth of corn, including temperature, spacing and competition, soil, and\nwatering.\n\n\n\nSoil Temperature For Growing Corn\n\n\n\nThe soil temperature must be at least 50 degrees Fahrenheit (10 degrees Celsius) for corn seeds to germinate and grow. In order to ensure that you don\u2019t kill your corn seeds or inhibit their growth, be sure to wait to plant corn seed until a few weeks after the last frost in your area. To find the last frost date for your area, check out this frost date calculator from the Old Farmer\u2019s Almanac.\n\n\n\nOnce corn plants germinate, they can withstand light frosts.\n However, soil temperatures should\nideally be 60 to 85 degrees Fahrenheit (16 to 29 degrees Celsius) in order to\nallow corn to thrive.\n\n\n\nOnce corn has germinated and sprouted, it can tolerate frost, but ideally soil temperatures will be 60 to 85 degrees Fahrenheit (16 to 29 degrees Celsius).\n\n\n\nFor more information, check out this article on growing corn from the University of New Hampshire Extension.\n\n\n\nIf you are worried about extreme temperatures, you can put mulch over the soil around your corn to insulate against temperature fluctuations on cool nights or hot days. Wood chips, grass clippings, leaves, straw, pine needles, or even compost will all work as mulch to insulate your soil.\n\n\n\nFor more information, check out my article on mulch and compost.\n\n\n\nSpacing and Weeding For Corn\n\n\n\nWhen planting your corn seeds, space them 3 to 4 inches (7.5\nto 10 centimeters) apart in a row, sown to a depth of 1 inch (2.5 centimeters). Leave 2.5 to 3 feet (0.8 to 0.9 meters)\nbetween rows, to give you space for watering, fertilizing, weeding, and\nharvesting your corn.\n\n\n\nCorn given plenty of space between plants is more likely to grow taller and yield healthy ears.\n\n\n\nIf you plant your corn too close together, the plants will\ncompete with one another for water and nutrients. Most likely, you will end up with ears of\ncorn that are small or missing some kernels.\n\n\n\nFor more information, check out this article from Texas A & M University on corn spacing.\n\n\n\nAlso, make sure to weed regularly to prevent your corn from\nhaving to compete with other plants. \nSome weeds may try to grow up your corn, using the plant itself as a\ntrellis.\n\n\n\nSoil For Growing Corn\n\n\n\nThe ideal soil pH for growing corn is between 5.5 and 7.0\n(somewhat acidic to neutral). Outside of\nthis range, some nutrients in the soil may become unavailable to the roots of\nyour corn.\n\n\n\nIf your pH is too low (acidic), you can add lime (calcium carbonate) to raise the pH. For more information, check out my article on raising soil pH.\n\n\n\nIf your pH is too high (basic), you can add sulfur to lower the pH. For more information, check out my article on lowering soil pH.\n\n\n\nOf course, before you add anything to your soil, you should always do a soil test to find out if your soil pH is off-balance. For more information, check out my article on how to do a soil test.\n\n\n\nIn addition to telling you the soil pH, a soil test will\ntell you the nutrient levels in your soil. \nIf you send a soil sample to your local agricultural extension, they can\nalso give you detailed advice about how to treat your soil. Just make sure to tell them what you are\ntrying to grow in your garden.\n\n\n\nSome common signs of nutrient deficiencies in corn are leaves that turn different colors. Use a balanced fertilizer, such as 10-10-10, to cure such nutrient deficiencies.\n\n\n\nWhite leaves can often mean a nitrogen deficiency. Purple leaves often mean a phosphorus deficiency. For more information, check out my article on diagnosing nutrient deficiencies.\n\n\n\nRemember that soil compaction can also cause growing problems for corn. To keep your soil loose, be sure to add compost to provide organic material to your soil.\n\n\n\nThis will help the soil to drain away excess moisture during wet weather and to retain water during dry spells. For more information, check out my article on how to make your own compost.\n\n\n\nAdding compost to your soil provides extra organic material and nutrients for your corn.\n\n\n\nWatering Your Corn\n\n\n\nAs with most plants, the best way to tell if corn needs\nwater is to test the soil with your fingers. \nDig down to a depth of 2 to 3 inches, and if the soil is dry, you can\nwater your corn.\n\n\n\nWater your corn when the soil is dry to a depth of 2 to 3 inches.\n\n\n\nIf you see your corn leaves wilting in the middle of a hot\nday, check the soil and if it is dry, water immediately. Otherwise, plan on watering deeply in the\nmorning, when the sun is not yet hot enough to quickly evaporate the water.\n\n\n\nWatering deeply and less frequently encourages stronger roots than shallow, frequent watering. Remember that it is possible to over water your plants - for more information, check out my article on over watering.\n\n\n\nConclusion\n\n\n\nBy now, you have a better sense of the height, ear size, and\ndays to maturity for some difference varieties of corn. You also have some ideas about how to give your\ncorn the best chance to grow tall and healthy.\n\n\n\nI hope you found this article helpful \u2013 if so, please share\nit with someone who can use the information. \nIf you have any questions or advice of your own about growing corn,\nplease leave a comment below.
