Corn plants come in many different varieties. They all grow as individual stalks with leaves and eyes. The major difference, other than the use, flavour and appearance of the corn, is the height that the stalks attain once the plant is fully mature. Keep reading to find out how tall does sweetcorn grow. While there are other types of corns, sweetcorn is the most popular variety grown for eating fresh, and freezing or canning for later use. The height of sweetcorn is a major factor in determining its feasibility for growing among gardeners.
How Tall Does Sweetcorn Grow – What’s In Its Height?
So why talk about the height of sweetcorn at all? Isn’t it just the ear of corn that should concern us? While it’s the only those sweet corn kernels that go in our tummy, height is just as important. It will affect maintenance, and in many cases, also the success possibility.
Growing taller sweetcorn is very problematic in windy areas. The tall stalks may even break under the pressure of a strong wind before the ears fully develop. The best solution is to choose low-growing varieties at the time of planting. A smaller height will make sure that the stalks aren’t blown off the ground in the face of a storm.
Height Of Sweetcorn Compared To That Of Other Corn Varieties
Sweetcorns generally grow much shorter than the field corn varieties. Field corns are grown as livestock feed, and it’s the stalk that’s the productive part. Taller stalks are the most desirable ones in this case since they contribute to a bigger yield, i.e. more feed for livestock. The field corn stalks can reach to a height of around 14 feet. Sweetcorn, on the other hand, usually only grows to about 4 to 5 feet for early season varieties and up to 7 feet for late-season varieties.
Besides field corn and sweetcorn, popcorn plants are also widely grown for their exploding kernels. “Tom Thumb” varieties grow shorter, attaining a height of barely 3 feet. In comparison “Strawberry” varieties grow a bit taller to around 5 feet.
