How to Store Sweet Corn
Corn is one of the most well liked vegetables during the summer months. It is available fresh on roadside stands, markets and grocery stores from June until August. Sweet corn is most tender and sweet if it is eaten the same day it is harvested or purchased. However, if not, it can be stored in several ways for long-term use.
Store sweet corn in the refrigerator. Keep the corn in the husks, and place them in the crisper drawer of your refrigerator. Sweet corn not only goes bad quickly, but it also loses its sweetness over time. For these reasons, use refrigerated corn within two days.
Freeze corn still on the cobs. Remove the husks, and blanch the ears of corn by boiling them for 7 to 11 minutes. Drain and then immediately dip them in cold water, or pour cold water on top to stop the cooking. Drain the ears well, and place them in freezer-safe bags. Remove as much air as possible to avoid freezer burn. Use frozen ears of corn within one year.
Freeze corn kernels. Remove the husks, and use a knife to remove the kernels. Generally, remove only about ¾ of the total depth of the kernels. Blanch the corn kernels for only about 5 minutes in boiling water. Immediately drain and cool in cold water. Place the kernels in freezer-safe bags, being sure to remove as much air as possible. Alternatively, you can store the kernels in freezer-safe containers; however, you should fill the container so that is 1/2 inch below the rim. Use frozen corn kernels within 3 months.
Water Sweet Corn
Amending and watering the soil before sowing sweet corn provides moist conditions for the sprouting seeds. Draw a hoe 1 inch deep through the soil to create rows 12 inches apart, or spaced according to the instructions on the seed packet. Water the rows thoroughly with fine spray on a garden hose and allow the water to drain away. Water young sweet corn plants regularly so that the soil stays moist, and spread mulch to help retain soil moisture. Water first thing in the morning so any moisture that gets on the leaves has time to dry during the day. Don't spread mulch near the plant stems where it could cause rotting. Weigh newspaper down with stones or spread an organic mulch over it.
