There are just some knowledge you need to have first before planting corn, such as;

  • They need warm soil. You should not plant corn during the cold weather cause corn grows in warm temperatures, so it will not thrive when there is a snowfall.
  • We should plant corn in blocks and not in single rows, and soil temperature must be over 60 degrees Fahrenheit. You should not plant them in bulk, but instead, plant your first round this week and then plant another round, a couple of weeks later.
  • Corn should be 1.5 to 2 inches deep in the soil and then must be 4 to 6 inches apart with rows spaced 30 to 40 inches apart. Mind the distance as well, if you want to grow different varieties of corn. They should be planted apart.
  • Sometimes, cross-pollination happens, and this causes an unfavorable result.
  • It is ideal to soak corn seeds overnight so germination will take place faster. When they are already planted, ensure that their water needs are being provided.
  • Use soil that is compost or manure ready and soil that is not soaked in water.
  • Just like any other plant, corn needs sunlight to grow fully. You should place them where they can get enough of it, as this will help in their growth speed.
  • Watering your corn for an inch every week is ideal. If there is not enough water during the first phase of corn growing, you will find your corn missing kernels. Applying water to the soil surface is the key instead of using a sprayer from above.
  • Weeds can be the enemy of corn, so be sure to remove weeds soon as you notice them creeping on the soil, you can also apply mulch to help prevent weeds from growing.

Problems That You Can Encounter When Growing Corn

Just like other plant varieties, corn can also have diseases, and there can be pests attacking them. Preventing such problems from happening is what you should watch out for.

Aphids

These pests can stunt the growth of your corn as it drains the sap from the leaves. They also leave sticky substances on the leaves that may cause mold to develop, which is another problem for your corn.

When there are also weeds around the soil, aphids can also get attracted to those. The easiest way to remove these aphids is by a blast of water and a bit of neem oil spray so they will not come back to infest your plants again.

Cutworms

These so-called “worms” are seed eaters that will kill emerging young plants before they can even fully grow.

They usually attack at night while hiding in the soil during the daytime.

You can protect your corn by surrounding your plant stem with a tin foil necklace so the cutworms cannot get closer to the seedlings.

There are also available products in the market that you can use to spray on the worms to eliminate them for good.

Caterpillars Or European Corn Borer (Ostrinia Nubilalis)

These pests will leave your corn stalks chewed and munched inside. They will leave your cob hollow, plus they will eat on the stems as well.

By being mindful of the appearance of your corn plants, you can prevent such disease from killing your entire corn plant.

Mosaic Virus

16 Tips For Successful Corn-Growing

During Planting

  • You must pick the right soil to plant your corn. It must be moist, well-drained, and have enough organic matter or aged compost. There should also be enough sun that the corn will require.
  • Pick the right time to do the planting, or else your corn will not emerge because of cold and damp soil. There should be enough warmth in the soil.
  • Using nitrogen-rich cottonseed or soybean meal is ideal. Insufficient nitrogen in the soil may cause yellow leaves while tassels are forming.
  • Watch out for phosphorous deficiency, and this will leave purple margins on the corn leaves, and it may stunt the growth.
  • Using raised beds or mounds as this will help your corn grow fast.
  • It requires enough space as you plant your corn. You can either use short, multiple rows or blocks that are 15 inches apart. Plant corn when the soil has a 60 to 2degree Fahrenheit temperature.
  • Do not plant them close together cause this will cause small-eared corn.
  • Plant just enough so that the pollen from male tassels will be distributed evenly and will not cause a shriveled kernel or incomplete kernel development.

Caring for your Corn

  • Watering your corn regularly is the key, but you must not get the plants soaked up, and 1.5 to 2 inches of water is enough every week. Using mulch is also perfect as this will keep the soil moisture intact.
  • Applying water at the surface of the soil is the best way to water your corn instead of spraying water above. This will cause the pollen from the flowering tops to get washed out.
  • Inadequate water may cause the leaf edges to roll inwards as it leaves the plant with not enough moisture.
  • Check on your plants every day and ensure that you are on the lookout for pests and disease as well as weeds. We also consider weeds “pests” as it competes with the nutrition that is supposed to be for your corn plants.

Your corn harvest

  • When you notice your corn tassels are turning brown and cobs are swelling, this is the best time to harvest your corn as they are milky and they will taste perfect.
  • You can also pierce a kernel and check for ripeness. If there is the presence of milky liquid on the kernel, then this shows that it is at its prime ripeness and is ready for harvest.
  • Usually, it occurs between 18-20 days after tasseling.
  • You only need to grab the ear, twist and pull in a downward motion and snap quickly.

You can either eat the harvested corn soonest time or preserve them immediately after picking.
