One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Sierra Vista you can estimate when it's the best time to plant millet by using the USDA zone info.

It's probably not a good idea to plant millet until after all chance of frost has passed because they require warm weather.

The earliest that you can plant millet in Sierra Vista 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 millet and expect a good harvest is probably August. You probably don't want to wait any later than that or else your millet may not have a chance to fully mature. If you are starting your millet indoors then you might be able to get away with starting them a little bit earlier.
