When Can I Plant Corn In Utah?

Corn is a tender vegetable plant, which means that it cannot tolerate temperatures below freezing (32 degrees F or 0 degrees C - the temperature at which water freezes).  If it is still freezing at night then it it too cold for tender vegetables.  Therefore, you should plant corn starting several weeks before the average last frost date for your area.  This way when the tiny plants germinate, they will be safely past that frost date.   Generally, the last average frost date for the Wasatch Front is sometime around Mother's Day.  You can ask your neighbors or the folks at your local independent garden center when your average last frost date is.  You can extend your corn harvest in summer and fall by succession planting your corn seeds.
