The USDA Zone info is a great tool for gardeners to help us figure out your gardening schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of getting a good idea when it's possible to plant corn is to check out the USDA zone info for Zone 8a.

Planting Calendar for Corn

Frost tolerance for corn:	Not tolerant of frost.
When to plant:	After the last frost.

Corn do not do well in cold weather which tells us that you need to wait until it warms up after the last frost before you can plant them.

The earliest that you can plant corn in Zone 8a is April. However, you really should wait until May 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 few weeks earlier.

Last Frost Date

In Zone 8a the average date of last frost happens on March 15. In the coldest months of winter you can expect an average low temperature of 10°F.

Remember that the actual date of last frost is an average because it is based on the USDA zone info for Zone 8a and it will vary from year to year. Half of the time in Zone 8a you get surprised by a frost after March 15 so just be sure to be ready to protect your corn in the event of one of those late frosts.
