How to Start Corn From Seeds Indoors

Overview

Corn has fed humans for centuries. Don't buy corn in the grocery store when you can grown your own and enjoy crisp, sweet corn fresh off the corn stalk. Get a head start on the growing season by starting your corn seeds indoors. Begin sprouting the corn indoors a couple of weeks before the last frost date in your area--if you don't know your area's frost calendar, consult the Farmer's Almanac--so you can begin harvesting your corn as soon as possible.

Step 1

Arrange several peat pellets, available from most garden stores and nurseries, onto any tray that has a small lip. You will need one peat pellet for each corn seed that you want to start.

Step 2

Moisten the peat pellets by sprinkling them with water. The pellets will absorb water and expand to a height of about one to two inches.

Step 3

Bury a corn seed inside each peat pellet. Sink the seed approximately 1/2 inch to 1 inch deep.

Step 4

Place the tray in a warm area that's 65 to 75 degrees F, such as near a sunny window. Keep the peat pellets moist. The corn will germinate within 10 to 14 days.

Step 5

Transplant the sprouted corn outdoors once the last frost date in your area has passed. Bury the peat pellet to a depth at which the base of the corn seedling's stalk is level with the surrounding soil.
