One of the first steps you take when you are determining 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.

A way of figuring out when you can plant primroses is to consult the USDA zone info for Savannah.

Since primroses do well in cold you can plant them earlier in the year than other frost tender plants.

The last month that you can plant primroses and expect a good harvest is probably September. You probably don't want to wait any later than that or else your primroses may not have a chance to really do well. You can get started a few weeks earlier by starting your primroses indoors.
