After you've planted and grown corn in your garden, the next step is harvesting. Harvesting corn is quick and simple after you've noticed its tassels turn brown and corn kernels mature. Pick and husk your corn using the proper technique, then store your corn by freezing, canning, or drying it. Once you've harvested your corn, you'll have plenty to use for baking or decoration!

Things You Should Know

  • To harvest corn, first, hold the ear tightly.
  • Then, pull the ear down hard while twisting so that the husk comes off of the stalk.
  • Use your fingers to pull away any remaining pieces of the husk.

  1. On average, sweet corn takes 60-80 days to mature. Make a note on your calendar to check for harvesting signs at around 60 days after planting. [1]
    • Corn harvests quickest in hot weather, especially temperatures over 90 °F (32 °C). [2]
  2. The corn tassel is the pollen-releasing stem on the tops of corn plants. As your corn matures, its tassels should turn from green to brown. Avoid harvesting the corn until the tassels' green color has disappeared completely. [3]
    • The tassels should turn brown about 3 weeks after the plant flowers. [4]

  3. Pull back the corn silk and squeeze a kernel between your finger and thumb. If the kernel releases a milky fluid, your plant is ready for harvest. [5]
    • If your corn kernels are not mature, they will be firm and won't release a milky fluid. If that's the case, smooth the silk and husk back over unripe kernels. Your corn will still mature without any problems. [6]
  4. Hold the stalk in your non-dominant hand to steady it while you harvest. With your dominant hand, grab a corn ear and twist it to the side. Pull the ear down and yank hard, then put your freshly-picked corn in a bucket or pile. [7]
    • Pulling on the cornstalk without twisting can kill the plant. [8]
  5. When left in room-temperature conditions for 24 hours, sweet corn loses 50% of its sugar. Store or prepare sweet corn the same day that you pick it for a fresher taste. [9]
    • You can store sweet corn in the fridge for 2-4 days by wrapping unopened husks in damp paper towels. [10]
  6. the corn husk and silk. Pull on the husk leaves one at a time until you have completely exposed the small silky hairs covering the kernels. Pick off the silk one hair at a time or use an old toothbrush to rub them off. [11]
    • Microwaving the corn can make it easier to husk. Set the microwave power to high and heat the unhusked corn for 2 minutes.
    • Put the silk and husks in a large container or trash bag to make cleanup easier.
  7. sweet corn to preserve it for 6-8 months. Blanch your corn in boiling water, then put your corn cobs in an airtight container and store it in the freezer. Freeze your corn for up to 6-8 months to have fresh-tasting corn no matter the season. [12]
    • You can also cut the kernels off of the cob with a knife before freezing for compact storage.
  8. sweet corn to preserve it for up to 5 years. If you don't plan on cooking your corn 2-4 days after harvesting, blanch your corn and remove the kernels with a sharp knife. Store the kernels in a jar and place them in a pressure canner to seal the jar. [13]
    • Canned corn tends to last longer than frozen corn at around 3-5 years. [14]
  9. Sweet corn makes a healthy, delicious side for most meals. You can cook fresh or preserved corn by boiling, microwaving, baking, grilling, or steaming it. [15]
    • If you do not want to store your sweet corn, cook it immediately after harvesting. [16]

Harvesting Flint Corn or Popcorn

  1. Unlike sweet corn, flint corn takes between 80-100 days to harvest. After 80 days have passed since planting, check your flint corn every day for signs of maturity. [17]
    • Corn harvests faster in temperatures over 90 °F (32 °C). If you live in a warm climate, your flint corn will mature closer to 80 days. [18]
  2. Corn tassels are the pollen-releasing stems on the tops of the plant. As your corn matures, its tassels should change colors from green to brown. Wait until tassels' green color has disappeared completely to harvest your corn. [19]
    • Corn tassels, on average, turn brown around 3 weeks after the plant flowers. [20]
  3. Flint corn and popcorn kernels should be dry and firm. Press on a corn kernel between your finger and thumb and, if it feels hardened, pick it as long as the tassels are brown and 80 days have passed since planting. [21]
    • If the corn kernels aren't quite matured, smooth the silk and husk back over. [22]
  4. Hold the stalk in your non-dominant hand to steady it and, with your dominant hand, twist the ear once to the side. Pull the ear downward and yank it off of the stalk, placing your freshly-picked corn in a bucket or pile. [23]
    • Pulling on the cornstalk without twisting can kill the plant. [24]
  5. Find an empty indoor space, like a garage or storage shed, to store your corn. Tie a length of twine around each corn cob and hang them from the ceiling or rafters. Let them hang for about 2-3 weeks, then transfer them to a dry container like a bucket or a storage bin. [25]
  6. If you have a corn mill or a high-powered blender, you can use your flint corn for cornmeal. Otherwise, flint corn can make a cheap feed for livestock. [26]
    • Cornmeal is a healthy, filling flour that you can use for cornbread, polenta, tamales, and other dishes. [27]
    • You can also use flint corn as an autumn decoration.
  7. After drying your popcorn cob, pull the kernels off with your hand or cut them off with a knife. Store them in a dry, airtight container until you're ready to cook with them. [28]
    • Although popcorn is a type of flint corn, it is the only corn variety that pops when you heat it. Do not try making popcorn from other varieties.
  8. Heat popcorn kernels to cook them. Depending on your preferences, you can microwave popcorn or heat it over a stove top. Keep the kernels under constant heat until they pop into light, fluffy popped corn.
  9. Like other flint corn varieties, you can grind popcorn into corn meal. If you want to use popcorn for baking, grind it using a high-powered blender or a corn mill.
    • You can also use popcorn as livestock feed, if preferred.

    Unpopped popcorn kernels are best stored in an airtight container, such as a sealed plastic bag or a glass jar with lid. Once you've opened the commercial packaging, it's a good idea to transfer unused popcorn kernels to the glass or plastic airtight storage container. Store such popcorn kernels in a cool, dry place. Once popped, popcorn can be stored in an airtight container or in the freezer but you'll find more instructions for freshly popped popcorn in the wikiHow: How to Keep Popcorn Fresh .

    The best time to harvest corn is right before you're about to use it, as that allows it to be at its best and sweetest. Some claim corn is best picked in the early morning but since few people will be cooking and eating it then, it's probably best to harvest just before use.

  • Question
    Is there any reason to cut the top off the corn stalk after the corn starts growing?
    Alex Glover
    Community Answer
    No. The only trimming you want to do is to pull smaller stalks that are within about six inches of bigger ones. Trimming the top risks losing the tassel (the male part of the plant) and then you'll have a tough time getting corn. Corn has to cross-pollinate. That's why you'll get very little corn if you only plant one row. It generally takes four or more rows to get a good harvest, or you can plant them in unorganized groups of six or more plants. The wind, bees, and other insects will carry the pollen from the tassel to the silk (the female part). The silk, which is between the husk and the ear of corn, is actually the flower.

      Tips

      • Your corn plants may not mature all at once. Check each plant individually and harvest them as they mature. [29]
        Thanks

      • Each corn stalk should provide 1-2 ears of corn, depending on the variety and size of the plant. [30]

      • If you liked how your harvest turned out, keep 10% of your seeds for next year's planting season. Pick the seeds from an ear of corn and store them in an airtight bag. Keep the bag in a dark, dry storage area until next planting season.

      About This Article

      Article Summary X

      To harvest sweet corn, wait until 60-80 days after planting it or until the tassels on the corn plants start to turn brown. You can also squeeze the kernels to see if a milky fluid is released, which is a sign that the corn is ready to be harvested. Then, twist each corn ear off of its stalk while pulling down on it, and put the corn in a bucket or pile. When you're finished, try to prepare the corn on the same day so it doesn't lose all of its flavor. To learn how to harvest flint corn or popcorn, scroll down!
