Growing sweet corn is a fun and rewarding gardening project that can provide you with delicious, fresh corn to enjoy all summer long. Sweet corn is a popular variety of corn that is typically consumed as a fresh vegetable, rather than being dried and ground into cornmeal. It is sweet, crunchy, and a favorite among many home gardeners. Here is a guide to help you grow sweet corn in your own garden.

Before planting:

  1. Choose a sunny location in your garden for your sweet corn plants. Sweet corn needs at least six hours of direct sunlight each day to grow well.
  2. Prepare the soil by tilling it to a depth of at least 6 inches. Add compost or well-rotted manure to the soil to improve its fertility. Sweet corn is a heavy feeder, so it benefits from nutrient-rich soil.
  3. Plant your sweet corn seeds in rows, spacing them about 8-12 inches apart. Plant the seeds about 1 inch deep in the soil. Water the seeds well after planting.

During growth:

  1. Water your sweet corn plants regularly, providing them with about 1 inch of water per week. Water the plants at the base, avoiding getting the foliage wet to prevent fungal diseases.
  2. Fertilize your sweet corn plants every two weeks with a balanced fertilizer, such as a 20-20-20 formula. Follow the instructions on the fertilizer package for the correct amount to use.
  3. Control weeds by hoeing or hand-pulling them regularly. Sweet corn plants can be sensitive to weed competition, so it is important to keep the weeds under control.
  4. Protect your sweet corn plants from pests and diseases. Corn earworms and cutworms can be a problem, so you may need to use an insecticide to control these pests. Keep an eye out for diseases such as corn smut and corn rust, and treat as necessary.


  1. Sweet corn is ready to harvest when the silks at the top of the ear turn brown and the kernels are plump and milky. This usually occurs about two months after planting.
  2. To test if the corn is ready to harvest, gently squeeze a kernel with your thumb. If the kernel is soft and yields to the pressure, it is ready to be harvested. If the kernel is still hard, it needs more time to mature.
  3. Use a sharp knife or scissors to cut the ears of corn from the plant, leaving about an inch of stem attached to the ear.
  4. Enjoy your sweet corn fresh, or preserve it by freezing or canning. Sweet corn is best when eaten within a few days of harvesting, as it will lose its sweetness over time.

With a little bit of care and attention, you can enjoy a bountiful harvest of sweet corn in your own backyard. Happy gardening!
