What is the USDA Hardiness Zone Map?

The USDA Hardiness Zone Map is a map that divides the United States into 10 different zones based on the average annual minimum temperature. The zones are numbered from 1 to 10, with Zone 1 being the coldest and Zone 10 being the warmest.

The USDA Hardiness Zone Map is used to help gardeners determine which plants are best suited for their climate. Plants that are hardy in a particular zone can withstand the average annual minimum temperature for that zone. For example, a plant that is hardy in Zone 5 can withstand temperatures as low as -20 degrees Fahrenheit.

The USDA Hardiness Zone Map is a valuable tool for gardeners in Wisconsin, as the state has a wide range of climates. Wisconsin is located in USDA Hardiness Zones 4a, 4b, 5a, and 5b. This means that gardeners in Wisconsin can grow a wide variety of plants, from cold-hardy perennials to warm-season annuals.
