Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Snowflake you can estimate when it's a good idea to plant potatos by looking at the USDA zone info.
