Sweet corn grows best on well-drained soils that have a good water-holding characteristic. If you grow sweet corn on sandy soil, irrigation is important for optimum pollination and kernel development. We generally look to plant when soil temps reach at least 55°F and the possibility of hard frosts has passed in Wisconsin.
For mid- or late season sweet corn production, no-till planting can be a benefit in relation to time, equipment, and labor. Sweet corn can be planted with a no-till planter in a minimally prepared bed.
