Before planting it is a good idea to find your USDA Zone info to figure out your garden 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 estimating when to plant corn is to use the USDA zone info for Cibolo.

Planting Calendar for Corn

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

Since corn are not cold tolerant it is necessary to wait until after the last frost when the weather gets warmer before you can plant them.

The earliest that you can plant corn in Cibolo 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 fully mature. You can get started a couple of weeks earlier by starting your corn indoors.

Last Frost Date

The average date of last frost is March 15 in Cibolo. It might get as low as 15°F during the coldest months of winter.

Always keep in mind that USDA zone info for Cibolo is not always accurate and the actual date of last frost changes from year to year. Half of the time in Cibolo there is a last frost after March 15 so always be ready to cover your corn in the event of one of those late frosts.
