How to Tell When Corn Is Ready to Pick: Expert Tips for Optimal Harvest

How to Tell When Corn Is Ready to Pick?

To determine if corn is ready to be picked, there are several indicators to look for.

First, check the seed package or consult the seed supplier for the recommended number of days until harvest for your specific variety of corn.

Secondly, tassels at the end of the ear of corn indicate readiness for harvest.

Additionally, the cornsilk should turn from light blond to dark brown.

When checking the kernels, make sure they are filled from the base of the ear to the tip, and tender kernels should release cloudy milk when pressed with a thumbnail.

The corn should have firm, dark green husks, and the silk should be dark and tightly held against the ear.

Ripe ears of corn are usually found at the top of the stalk.

To pick the corn, firmly grab the ear and snap it against the stalk before pulling upwards.

It is important to pick corn at its peak as the sugar content begins turning into starch within 24 hours of being picked.

Key Points:

  • Consult seed package or supplier for recommended harvest time
  • Look for tassels on the end of the ear of corn
  • Cornsilk should turn from light blond to dark brown
  • Kernels should be filled from base to tip, and release cloudy milk when pressed
  • Corn husks should be firm and dark green, silk should be dark and tightly held
  • Ripe ears of corn are usually found at the top of the stalk


Did You Know?

1. Did you know that the number of leaves on a cornstalk can help indicate when the corn is ready to pick? Fully matured corn usually has around 20 leaves on each stalk.

2. One peculiar way to determine the ripeness of corn is by paying attention to the corn silk. When the silk starts to turn brown and dry, it is a good sign that the corn is nearing its optimal harvesting time.

3. Interestingly, the “milk stage” refers to the stage of corn development when the kernels start producing a white, milky liquid when punctured. This is a reliable indication that the corn is ripe and ready to be enjoyed!

4. Have you ever heard of the “thumb test” for corn readiness? Once the kernels start to fill up the entire cob and you can press your thumb into one and see a milky liquid squirting out, it’s a sure sign that the corn is at its peak for picking.

5. In addition to visual cues, sound can also be a revealing factor when it comes to harvesting corn. A telltale sign that the corn is ready is when you gently shake the ear of corn, and you can hear a slight rustling sound as the kernels rub against each other.

Determining Corn Readiness

When it comes to picking sweet corn, determining its readiness can be a bit tricky. However, there are several methods you can use to ensure you harvest your corn at the optimal time.

First, it’s important to check the seed package or consult the seed supplier to determine the number of days until harvest for your specific variety of corn. This information will give you a general idea of when to expect your corn to be ready.

Another way to determine if your corn is ready for picking is by looking at the tassels. When the tassels have turned brown and dry, it is an indication that the corn is ready to be harvested. This is usually around 20 days after the first silks emerge.

Checking Corn Silk And Kernels

To confirm the readiness of your corn, check the cornsilk. The silk is the fine, hair-like strands that protrude from the top of each ear of corn. Initially, the silk will be light blond in color, but as the corn matures, it will turn dark brown. The change in color indicates that the corn is ready to be eaten.

In addition to the cornsilk, check the kernels themselves. Gently pull back the husk of the corn and ensure that the kernels are filled from the base of the ear to the tip. The kernels should be plump and juicy. To test their tenderness, press your thumbnail against a kernel. If it releases a cloudy milk-like substance, then the corn is at the perfect stage of ripeness.

Identifying Ripe Corn

Apart from checking the silk and kernels, there are a few other visual cues that can help you identify ripe corn. The corn should have firm, dark green husks that are tightly wrapped around the ear. The silk should also be dark and tightly held against the ear. Avoid corn with brown spots on the husk or dried up or black silks at the top, as these are signs of over-ripeness or potential disease.

Moreover, the ripest cobs are usually found at the top of the stalk. Start by examining the ears at the top of the plant and work your way down to ensure you harvest the corn when it’s at its prime.

Picking And Harvesting Corn

Once you have determined that your corn is ready for harvest, it’s time to pick it. To properly pick corn, firmly grab the ear with your thumb at the top and your middle finger closer to the base. With a quick snapping motion, pull the ear upwards, breaking it away from the stalk. Be careful not to damage the ear or the plant as you harvest.

Remember that once corn is picked, the sugar in the kernels begins to turn into starch. Within the first 24 hours of being picked, corn loses 25% of its sugar content. Therefore, it is best to consume freshly picked corn as soon as possible.

  • Firmly grab the ear with your thumb at the top and middle finger closer to the base.
  • Use a quick snapping motion to pull the ear upwards, breaking it away from the stalk.

Cooking Fresh Corn

When it comes to cooking fresh corn on the cob, boiling is the simplest and most popular method. To start, choose a pot that is large enough to hold the corn and enough water to fully cover the ears. Remove the husk and silk from the corn and drop the husked ears into boiling water. Cook until the water returns to a boil, which should take approximately 5-7 minutes.

If you prefer to grill or bake your corn, you have those options as well. When grilling, you can either remove the husks or leave them on and soak them in water beforehand to prevent burning. If baking, rub softened butter on the corn kernels before cooking to add extra flavor. Grilling should be done for about 20 to 25 minutes at 375°F.

After cooking, the corn can be eaten directly off the cob or the kernels can be sliced off with a knife and used in various recipes. If you have leftover cooked corn, it can be wrapped in aluminum foil and stored in the fridge for three to five days.

Storing And Freezing Corn

When choosing corn, look for bright green husks that are tightly wrapped around the cob. Additionally, gently squeeze the ear to ensure that the kernels inside are plump and healthy.

To store uncooked corn, keep it unwashed and unpeeled in a sealed plastic bag in the crisper drawer of your refrigerator for about five to seven days. This will help maintain its freshness and flavor.

If you have excess corn and want to freeze it for future use, start by shucking and blanching the corn. Blanching involves briefly boiling the corn ears in water and then immediately placing them in ice water to stop the cooking process. After blanching, cut the kernels off the cob and place them in freezer-safe bags or containers. Frozen corn can be stored for up to six months.

Frequently Asked Questions

How do you pick up good corn?

To pick out good corn, you want to look for plump kernels that give a little bit of resistance when pressed gently with your thumb. The kernels should have a certain firmness to them, indicating that they are not overly mature or dried out. Avoid corn that feels mealy or hard under the husk, as this could be a sign of picking it too early or keeping it stored for too long after harvesting, respectively. The key is to find a balance where the corn is ripe and juicy, but not too mature or dry.

What color is corn when harvested?

When corn is harvested, it takes on a vibrant golden hue. The kernels, once lush and green, ripen to a warm and inviting shade of yellow. This color transformation signals the peak of corn’s sweetness and tenderness, making it a delightful visual treat on the dinner table. So, when harvested, corn reveals its true colors, radiating a sunny and appetizing yellow that beckons to be enjoyed.

How long does corn last when you pick it?

The freshness of corn can be preserved by storing it in a sealed plastic bag, unwashed and unpeeled, within the crisper drawer of your refrigerator. By doing so, the corn can maintain its quality for approximately five to seven days, allowing for more extended usage. It is advisable to utilize the corn as soon as possible after purchasing or harvesting it to fully enjoy its optimal taste and texture.

What color corn is healthiest?

When it comes to the healthiest color of corn, the answer lies in the vibrant yellow variety. The yellow color of the kernels is indicative of the presence of beta carotene, a naturally occurring pigment. This compound not only adds nutritional value but also converts into essential vitamin A during digestion, providing an extra edge in terms of health benefits compared to white corn. Therefore, choosing yellow corn can offer a slight nutritional advantage towards meeting your daily vitamin A requirements.
