One of the first steps you take when you are figuring out your gardening schedule is find your 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 Savannah you can figure out when it's the best time to plant digitalis by checking out the USDA zone info.

Digitalis do well in some cold which tells us that you can plant them a little earlier in the year than plants that are more sensitive to the cold.

The last month that you can plant digitalis and expect a good harvest is probably September. You probably don't want to wait any later than that or else your digitalis may not have a chance to fully mature. Starting your digitalis indoors is a great way to get them started a few weeks earlier.
