One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Gillette you can estimate when you can plant corn by reviewing the USDA zone info.

Planting Calendar for Corn

Frost tolerance for corn:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

Since corn do not do well in cold weather you really should wait until after the last frost has passed before you can plant them.

The earliest that you can plant corn in Gillette is May. However, you really should wait until June if you don't want to take any chances.

The last month that you can plant corn and expect a good harvest is probably August. Any later than that and your corn may not have a chance to really do well. If you are starting your corn indoors then you might be able to get away with starting them a couple of weeks earlier.

Last Frost Date

In Gillette the average date of last frost happens on May 15. In the coldest months of winter you should expect an average low temperature of -25°F.

Since the USDA zone info for Gillette is not always accurate the actual date of last frost changes from year to year. Half of the time in Gillette there is a last frost after May 15 so always be ready to cover your corn in the event of a late frost.
