One of the best tools that you have as gardeners to help us estimate your gardening schedule is the 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 Fishers you can figure out when you can plant alstromeria by using the USDA zone info.

Alstromeria do well in moderate cold which tells us that you can plant them a little bit earlier than plants that are more sensitive to the cold.
