Sweet corn is an easy vegetable to grow.
The harvest season can be extended either by planting several plantings of the same variety at ten day intervals until June 15 or by planting an early, a mid-season and a late variety of sweet corn all at the same time. Sweet corn is a tender vegetable and should not be planted until the soil is warm. It may be planted around May 10 in the southern part of the state and around May 20 in northern areas. Sow seed in hills 2 feet apart or drop seed singly in rows. Thin corn plants to no more than two plants per hill or single plants one foot apart in a row.
