Growing the Sweetest of the Sweet Corn
Most of us don’t have a big farm that we can grow acres of sweet corn, but we still want that fresh sweet corn taste out of the garden. It is still possible with a small garden but you have to follow a few rules.
First of all corn plants are monoecious, meaning that there are both male and female flowers on the same plant. In corn, male flowers are the tassels at the top of the plant. The female flowers are in the junction of the leaves and stems. The female flowers become the silks of the corn, and when the wind blows, the pollen falls from the tassels to the silks for pollination. Each silk leads to a kernel of corn. Poor pollination leads to an ear that is not fully formed. In a small garden for the best pollination do not plant one long row but several short rows.
Plant corn around May 5th, or when the soil temperatures reach at least 50 degrees F. Corn seed will rot in cold soils. The Xtra sweet varieties require warmer soil temperatures, at least 60 degrees F.
Corn seeds require frequent watering for germination, so soak thoroughly. You should plant 2 or 3 seeds 12 to 15 inches apart in rows about 3 feet apart. Plant an inch deep, except for the Xtra sweet varieties. They will need to be planted at three quarters of inch deep.
Corn prefers a rich soil with plenty of nitrogen and moisture. As always add plenty of compost. It is very important to water plenty for healthy corn plants during the growing season. Fertilize when your plants reach 12 – 18” tall with a fertilizer high in nitrogen.
When picking the perfect sweet corn for your appetite you may choose from the following.
SU – This is the non enhanced sweet corn, the standard. These are best used and eaten in a short amount of time, due to the starches converting to starches rapidly
SE – These are the sugar enhance varieties. They have an increased sweetness and tenderness. The sugar conversion to starch is at a slower rate and will store longer.
Xtra-sweet – The very sweet varieties. Plant away from other varieties, they should not be near other types for cross pollination.
You will be able to pick your sweet corn when the juice in the kernel appears milky as you puncture a kernel with your thumbnail. This “milk” stage lasts only a short time, especially in hot weather.
The corn earworm is probably the most destructive corn pest. The insect develops from moths that lay eggs on the silks of the ears. The eggs hatch and the larvae move into the tips of ears, feeding on the kernels. Insecticides or mineral oil can be applied to the ears to lessen the earworm damage, but little can be done once the worms are inside the husks. Applications are necessary from tasseling until the silks begin to dry up, usually about a two-week period.
We have corn seed available in bulk and on our seed racks, as well as the fertilizer and compost you will need to get that perfect sweet corn. As always you can stop by to ask further questions.
