How to Grow Perfect Sweet Corn in Your Backyard Garden

Sweet Corn

Corn is a popular crop to grow and eat, especially when it’s fresh. It’s also simple to grow in your backyard garden, as long as you have straight, tall stalks. The ears of corn will have soft silk-covers and husks on the outside.

Most types of corn look similar from the outside, but sweet corn can be white, red, yellow, or bicolor. Modern sweet corn varieties are created to mature at different times during the growing season; however, those that mature later tend to be sweeter.

The annual sweet corn plant grows quickly and can be harvested two months after planting or three months after it’s suitable for consumption.

  • If your soil is heavy or clay-like, consider amending it with some organic matter before planting.
