How Much Sun Does Corn Need?

Corn is one of the most popular plants to grow in your garden. It’s used for food and animal feed, and it has plenty of uses as a decorative plant. If you’re trying to grow corn in your yard, you might be wondering how much sun does corn need?

How Much Sun Does Corn Need?

Corn is a perennial crop, meaning that it grows and produces more seeds in the same place year after year. This makes it possible to grow corn as a crop on your homestead or farm, but if you’re not sure how much sun corn needs for this purpose, here’s what you need to know:

  • Corn needs full sun to grow. To produce ears of sweet golden kernels, corn plants require at least 6-8 hours of direct sunlight each day during their growing season (typically May through September). In addition, they should be planted in soil that has rich nutrients and adequate moisture levels; otherwise, they may struggle with disease or yield less than ideal results.
  • Corn can be planted in both spring and fall depending on where you live—this depends on your climate zone and whether there are any diseases affecting local crops right now—but most people plant theirs around June so they have plenty of time before frost sets in again later that autumn/winter season!

Do Corns Prefer Full Sun?

You’ll need to give your corn plants 6-8 hours of sunlight a day. If you want the best results, try to find a spot for them that gets at least six hours of sun every single day.

Corn is an annual plant that grows in warmer climates and can tolerate high temperatures. This means it can grow in almost any region where there is enough water and space for it to grow without being damaged by strong winds or other weather conditions.

Do Corns Do Well In Shade?

Corn is a heavy feeder and needs full sun. However, it can also tolerate partial shade and even some dappled shade.

Corn will do well in a forested area where there is some light filtering through the leaves of trees, but not so much that it doesn’t get direct sunlight for at least part of the day.

Corn tends to do poorly in deep shade; if you want to grow corn in an area that receives less than five hours of direct sunlight per day, consider growing other crops instead or supplementing with artificial lighting.

Where Do Corns Grow Best?

Corn is a warm-season crop, which means it grows best in hot and dry weather. Corn requires lots of sunlight and also requires good soil drainage. The most suitable crops for corn are sandy soils that drain well, like loam or silty sand. These types of soils will allow water to evaporate from the surface quickly so that more moisture can be added as needed by irrigation.

Corn needs about 85-95 days from planting to harvest, depending on variety and growing region, so make sure that you plan ahead before you plant your corn seeds!

Can Corns Get Too Much Sun?

Yes, corn plants can get too much sun.

If you live in an area with a climate that receives more than 6 hours of sunlight per day, you may have noticed that your corn plant is growing very tall and thin. This can lead to poor pollination and reduced yields (fewer seeds). The best way to prevent this from happening is by planting your corn earlier in the season so that it has time to mature before your area gets so hot.

Signs Your Corns Aren’t Getting Enough Sunlight

If you’re growing your own corn, you need to make sure that it gets enough sunlight. If your corn isn’t getting enough sunlight, it’s going to produce fewer ears of corn and the ears that do grow will be smaller than they could have been.

Here are a few signs that your corn isn’t getting enough sunlight:

1) The leaves of the plant are yellowing or turning brown.

2) The leaves are curling up on themselves or looking like they’re wilting.

3) The leaves aren’t growing as fast as they should be.

How Often Does Corn Need To Be Watered?

Watering your corn often is a necessary part of keeping it alive and growing.

It’s not enough to just rely on rainfall. Even if you get an inch or two of rain every few days, that’s still not enough water for your corn plant to thrive. If you don’t water it every day (and sometimes twice a day), then the roots will dry out and die from a lack of moisture in the soil.

If you dig down into your soil with a stick or trowel, then check how wet it is before watering again. You want the top 2 inches (5 cm) of soil to be moist but not soggy or wet with standing water so that there won’t be any fungal diseases developing in there either!


With all this info in mind, it’s easy to see that corn needs a lot of sun. And as we know from the first post in this series, you can grow corn indoors! So next time you’re thinking about what kind of plants would do well for your growing space or garden, consider planting some corn seeds.
