For people who live in apartments or simply need an escape from the winter blahs, the idea of growing corn indoors may seem intriguing. This golden grain has become a staple of the American diet and is as much a part of our rural landscape as cows and tractors. But, to grow corn indoors, you have to be dedicated. Growing corn in containers in your home is not impossible, but can be difficult. Let’s look at what it takes to start indoor corn growing.

Planting Corn Indoors

Start with corn seed. If you are growing corn indoors, it is probably a good idea to plant a dwarf variety of corn such as:

  • Miniature Hybrid
  • Golden Midget
  • Early Sunglow

When indoor corn growing, the corn plants will be relying entirely on you for nutrients. Add plenty of composted manure or fertilizer to the soil for growing corn in containers. Corn is a heavy feeder and will need it to grow well.

Corn seedlings do not transplant well, so if you are growing corn in containers, just plant the seed straight into the container you will be growing the corn in. The container you choose should have ample room for 4 – 5 full size corn stalks. Use a wash tub or other large container for planting corn indoors.

Plant the corn seed 4 – 5 inches apart about 1 inch deep.

Once you get the corn seed planted, place the corn in plenty of light. This can be difficult when you grow corn indoors, as the available sunlight will not be enough. You will need to supplement the light. Add grow lights or fluorescent lights to the area where you will be growing corn indoors.  The lights should be as close to the corn as possible. The more artificial “sunlight” you can add, the better the corn will perform.

Check plants weekly. Water the corn as needed, when the top of the soil is dry to the touch. When planting corn indoors, the corn will typically need less water than corn planted outdoors. You will also need to keep a careful eye on not overwatering when growing corn in containers. This will cause root rot and will kill the plants.

As we said, growing corn indoors is no easy task. To grow corn indoors, you need to make sure that you have created the right condition for the corn to grow well. But once you have done this, planting corn indoors can be fun and rewarding.
