One of the best tools that you have as gardeners to help us determine 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.

The USDA zone info for Dallas can be looked at to estimate when it's the best time to plant corn.

Planting Calendar for Corn

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

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

The earliest that you can plant corn in Dallas 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. You probably don't want to wait any later than that or else your corn may not have a chance to grow to maturity. Starting your corn indoors is a great way to get them started a little bit earlier.

Last Frost Date

In Dallas the average date of last frost happens on March 15. It might get as low as 15°F during the coldest months of winter.

Since the USDA zone info for Dallas is not always accurate the actual date of last frost changes from year to year. Half of the time in Dallas last frost occurs after March 15 so just be sure to be ready to cover your corn in the event of one of those late frosts.
