What is a Frost Map?

A frost map helps determine the estimated first and last frost date in a given region and is a helpful tool to plan a garden. For maximum gardening success, combine the estimated frost dates with the hardiness zone of the plant(s) you want to grow.

You can find plants that are hardy in your region by inputting your zip code into My Garden Life's USDA Zone Finder.
