In Atlanta you can determine when it's the best time to plant alternaria by looking at the USDA zone info.

The last month that you can plant alternaria and expect a good harvest is probably August. If you wait any later than that and your alternaria may not have a chance to really do well. If you are starting your alternaria indoors then you might be able to get away with starting them a couple of weeks earlier.
