Types of Corn
There are many different types of sweet corn you can grow your garden, as well as popcorn, and dent corn (used for corn flour). The most limiting factor to growing corn is the amount of space you have in your garden. In order for proper pollination corn needs four to five rows, or ten to twelve hills depending on your planting method. If you have the space, growing sweetcorn is a great thing to do because you can grow much better varieties than you can buy in the store. There are three main types of sweetcorn su, sh2 and se. Su is a standard old-fashioned type sweetcorn and can be grown with no isolation from other types of corn. Sh2 must be separated from other types of corn because cross pollination will ruin the flavor. Se types are a cross between su and sh2, and do not require isolation from other types of sweetcorn. Su sweetcorn is the standard old-fashioned type sweetcorn, it has very good corn flavor but loses sweetness very fast and must be cooked the day it is picked. Sh2 to is called super sweet corn and is sweeter than the standard sweetcorn and will hold its sweetness for up to 10 to 12 days in the refrigerator. Se sweetcorn is a hybrid between the two and holds its sweetness for longer than the standard sweetcorn, but it’s not quite as sweet as the super sweet. Sweetcorn comes in three main colors types but that’s mostly a choice of aesthetics, the three colors are white, yellow, and bi-color which is both yellow and white.
Planting Corn

The main thing to consider when planting your sweetcorn is not to plant it too soon in the spring, because of the high sugar content of the kernels. If it’s too cold the kernels will rot. It is recommended that the soil be 50°F for treated seeds and 60°F for untreated seeds. Corn is not too picky about soil types and will grow in almost any kind of soil. Corn should be planted an inch to two inches deep depending on the soil temperature and the dryness of the soil. If the soil is fairly cool you want to plant it shallower so it doesn’t rot in the soil, and if the soil is fairly dry you want to planted deeper so that seeds won’t dry out. Corn should be planted between six and twelve inches apart depending on the variety of the corn. Taller plants need more space to grow and spread out, and the shorter plants need less room to grow. Therefore it is always a good idea to read the seed package that you have. Rows should be spaced 32 to 36 inches apart, don’t space them too far apart or the corn will not pollinate properly and you will have very many empty spots on your ears. If you plant your corn in hills, space the hills about ten to twelve inches apart with two or three seeds in each hill. The rows between hills should also be 32 to 36 inches apart.


Once the corn gets to be about 10 to 12 inches tall it’s sometimes a good idea to mound soil around the rows at a depth of to about 4 to 6 inches, this helps prevent weeds and also helps the the corn to stand up to wind. Corn does require more nitrogen than most vegetables so it’s a good idea to fertilize your soil, if your soil is poor. When you’re corn is growing make sure that it gets an inch of water every week. Your seed package should have a number days until the corn is ripe. This is usually fairly accurate less it’s a fairly cool summer in which case you’re corn will take a week to 10 days longer to mature.

Problems to Watch For

Corn does have a few pests which can be a problem, the corn borer for one, this can be treated with Thuricide or BT. Corn smut can be a problem in wet damp years, this can be treated with a fungicide either a commercial type or an organic copper solution. The other main pests for corn are critters. The main one being raccoons, as well as woodchucks, possums, and blackbirds. The best solution for the ground animals is a good fence with electric wire on the top. Solar electric fencing can be bought at most home centers and hardware stores. Birds are a different matter. It’s usually easiest to try to scare them off. You can use a scarecrow, one of those plastic owls, or one of those shiny whirligig things.

Once your corn is ripe you’ll be enjoying some of the best sweetcorn you’ve ever had. I like to grow extra corn so that I can freeze some and enjoy the super sweet corn throughout the year. So get out there and get growing, and remember if you have any questions or problems, feel free to let us know at Contact , and ask any questions that you may like to ask..

The Debbie 2000 Corn Planter

Here is a video of expert gardener Mel planting his corn with the Debbie 2000 corn planter. It’s a hollow plastic broom handle with a bolt duct taped the bottom. The bolt is used for spacing. It sticks out about five  inches, which is the spacing between the seeds, and is about two inches above the bottom of the plastic broom handle, which is the depth that the seeds are planted.

It’s called the Debbie 2000 because Mel’s wife Debbie planted the corn, as Mel has a bad back and can’t bend over to plant corn. So she planted the corn until her knees got bad. That’s when Mel built the Debbie 2010.
