The first opportunity to plant alternaria in Biloxi should be determined by looking at the USDA zone info.

Since alternaria do not do well in cold weather you really should wait until after the last frost before you can plant them.

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