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 Snowflake you can figure out when it's a good idea to plant string beans by using the USDA zone info.
