Tips for Growing Sweet Corn

• Corn seeds should be planted in a spot that receives full sun, in well-draining soil.
• Plant sweet corn seeds approximately one inch deep, spaced about 9-12 inches apart
• Soil should have a temperature of about 60 degrees or above
• Sweet corn requires frequent watering to produce full, healthy ears. Once the tassels appear, you should provide at least one inch of water per week. Make sure the soil doesn’t dry out between waterings.
• Cross-pollination between supersweets and other genetic classes will turn corn kernels tough and starchy. This effect works both ways. Since corn is wind-pollinated, the supersweets should be isolated at least 250ft from all other non-sh3 corn (field, su, se, sb, sy, pop, ornamental etc.), use natural wind barriers and/or plant with 10-14 days maturity difference between varieties.
