Here in this segment let us talk about growing corn and that too specifically how to grow Corn in Square Foot Gardening.
What is Square Foot Gardening?
This is a technique that makes gardening productive and efficient in small spaces. It was developed by Mel Bartholomew who was a retired engineer and also an expert in backyard gardening with efficiency experts who gave us a better way to do vegetable gardening from the traditional ways.
How do you do Square Foot Gardening?
Square Foot Gardening means you can take a garden bed that could be 4 feet by 4 feet or even 4 feet by 8 feet commonly or any size for that matter, and what you do is divide this bed in grids of the size of 1 feet squares with some sort of divider.
You can now use these grids to grow either the same variety of vegetables or grow different vegetables in each grid or just grow some common vegetables in a few grids and different in others, whatever suits you best depending upon how you would like to arrange it and what you would want to grow and in what the quantities.
When you choose the seeds or the seedlings that you are planting in each grid the idea is each grid is assigned a single kind of vegetable. While doing this you must know the density of the size of the plant you are wanting to grow.
For eg. If you are growing radishes in one grid, you can sow up to 16 seeds per square but if you are growing tomatoes you should plant just one plant in 1 square grid.
There is also an updated version of this technique that Mel Bartholomew updated in his book 20 years later.
It says that alternatively you can also make frames or raised beds of about 6 inches deep and these can be filled up with peat moss, vermiculture, and compost as that will be of a much richer quality than the basic garden soil.
The process is the same for corn square foot gardening.

How to Grow Corn in Square Foot Gardening?
Now that we understand what is square foot gardening we must realize that this technique was developed to make gardening easy for gardeners also thereby increasing efficiency.
Therefore if you are a home gardener or a beginner in gardening too this can be a very effective way to use up the limited space issues and turn it into an effective gardening area.
When we grow corn it is generally planted 4 to 6 inches apart in rows that are 30 to 36 inches apart which would mean you need a large space for growing corn. Square foot gardening gives you the efficiency to grow lots more corn plants in smaller spaces.
Let us see how we can grow Corn in the square foot gardening technique.
#1 Temperature Requirement for Growing corn
Depending upon the zone of America that you live in you must choose the best time to grow corn but generally, you can grow corn from 15th May to 10th June. This is because corn prefers a warm temperature and if you plant corn seeds in cold soil there are chances the seeds might rot and die.
Therefore it is preferred to plant the seeds of corn when the temperature is warm ideally 65 degrees Fahrenheit or 18 degrees celsius. If the temperature gets warmer that would be better but it should not go lower than that as it may adversely affect the growth.
If the cold spring season is unusual during this time in your location and it is not warm yet outside, you can start with the seeds in trays indoors as the warm temperature inside can make the conditions ideal for their germination.
#2 Preparing Soil to grow Corn in Square Foot Gardening
You should use a soil mix of peat moss, coarse vermiculture, and blended compost in equal ratios in your 6-inch deep square feet garden.
You can buy all three things from the market locally or online and you can also make your blended compost at home out of kitchen waste and some waste wood chips and mix them with some worm compost.
Healthy soil is absolutely crucial for the success of your square foot gardening. You can use mulch with wood chips to make your soil mix too. You won’t need additional chemical fertilizers as the moisture in this mix will help in providing the plant with nutrients.
If still, you feel the need to add something to the plants you can make compost tea for them that can act as a natural and effective fertilizer.
For making compost tea you must put the compost into a nylon cloth and place it in warm water. This makes the nutrients come inside the water which becomes compost tea. You can add this water to the base of the plants when the water cools down.
#3 Growing corn from Seeds
The plant grows through pollination and the corn plant has a part where the pollen is made that is called the tassel and the part that receives the pollen is called silk.
The silk part of the plant when receiving the pollen becomes the seeds or the kernel of the corn and if the silk does not get pollinated it doesn’t bear kernels or seeds.
This process happens from the bottom-most part of the silk that is attached to the cob of the corn and it grows upwards to the ear of the corn where we generally see lesser kernels.
The tassel starts shedding the pollen two to three days before the silk starts forming. The tassel sheds pollen for 5 to 8 days and the silk receives the pollen for 10 days and is no more receptive after that period. The silk of one stalk is rarely pollinated by the tassel of the same stalk.
Later on when the silk gets pollinated and the baby kernel starts forming. The silk part starts leaving the kernels and gradually turns brown and dry.
This way the plants keep getting pollinated and keep growing. To start with you must sow the seed of corn 1 inch deep into the soil.
Planting Process to Grow Corn in Square Foot Gardening

When the silk part of the corn turns brown and dry get ready to be harvested and picked up. Also, you can pull back the husk part of the corn and check the corn kernels by pricking them simply with your fingernails and if they start to drip out some milky color substance they are ready for harvesting.
