One of the best tools that you have as gardeners to help us determine your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Atlanta you can figure out when you can plant alstromeria by referring to the USDA zone info.

When to plant:	Up to 5 weeks before last frost.

Alstromeria do well in moderate cold which means that you can plant them earlier than plants that are more sensitive to the cold.

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

The last month that you can plant alstromeria and expect a good harvest is probably September. You probably don't want to wait any later than that or else your alstromeria may not have a chance to fully mature. If you are starting your alstromeria indoors then you might be able to get away with starting them a little bit earlier.
