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

The earliest that you can plant dahlias in Miami should be determined by referring to the USDA zone info.

Planting Calendar for Dahlias

Dahlias are not cold tolerant which tells us that it is important to wait until it warms up after the last frost has passed before you can plant them.

The earliest that you can plant dahlias in Miami is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant dahlias and expect a good harvest is probably November. You probably don't want to wait any later than that or else your dahlias may not have a chance to really do well. Starting your dahlias indoors is a great way to get them started a couple of weeks earlier.
