Wisconsin, also known as the Badger State, is located in the Midwest region of the United States. The state has a varied landscape, with forests, lakes, and prairies. It is an excellent place for gardening and agricultural activities. However, to ensure that your plants thrive, it is important to know your planting zone. In this article, we will explore what planting zone is WI and how it affects gardening.

What is a Planting Zone?

A planting zone is a geographical area that is defined by the average minimum temperature that occurs in that area. The United States Department of Agriculture (USDA) has created a map that divides the country into 13 different zones, each with a temperature range of 10 degrees Fahrenheit. The map is based on the average minimum temperature that occurs in each zone. The map is used to help gardeners and farmers determine which plants are best suited for their area.

How is Wisconsin Divided into Planting Zones?

Wisconsin is divided into four different planting zones: Zone 3, Zone 4, Zone 5, and Zone 6. These zones are determined by the average minimum temperature that occurs in each zone. The northern part of Wisconsin is in Zone 3, which has an average minimum temperature of -40 to -30 degrees Fahrenheit. The southern part of Wisconsin is in Zone 6, which has an average minimum temperature of 0 to -10 degrees Fahrenheit.

Zone 3

Zone 3 covers the northernmost part of Wisconsin, including cities like Ashland, Superior, and Hayward. This zone has an average minimum temperature of -40 to -30 degrees Fahrenheit. This means that the growing season is short, and gardeners need to choose plants that can survive in cold temperatures. Some plants that are suitable for Zone 3 include blueberries, chokecherries, and gooseberries.

Zone 4

Zone 4 covers the central part of Wisconsin, including cities like Wausau, Stevens Point, and Wisconsin Rapids. This zone has an average minimum temperature of -30 to -20 degrees Fahrenheit. This means that the growing season is slightly longer than Zone 3, and gardeners can choose plants that can survive in colder temperatures. Some plants that are suitable for Zone 4 include raspberries, currants, and hazelnuts.

Zone 5

Zone 5 covers the southern part of Wisconsin, including cities like Madison, Milwaukee, and Green Bay. This zone has an average minimum temperature of -20 to -10 degrees Fahrenheit. This means that the growing season is longer than Zone 3 and Zone 4, and gardeners can choose plants that are not as cold-hardy. Some plants that are suitable for Zone 5 include apples, pears, and cherries.

Zone 6

Zone 6 covers the southernmost part of Wisconsin, including cities like Kenosha, Racine, and Beloit. This zone has an average minimum temperature of 0 to -10 degrees Fahrenheit. This means that the growing season is the longest in Wisconsin, and gardeners can choose a wide variety of plants. Some plants that are suitable for Zone 6 include tomatoes, peppers, and cucumbers.

How Does Planting Zone Affect Gardening?

Knowing your planting zone is important because it helps you choose plants that are best suited for your area. Plants that are not suited for your planting zone may not survive the winter, or they may not produce as much fruit or vegetables as they would in a different zone. By choosing plants that are suited for your planting zone, you can ensure that your garden is productive and healthy.

It is also important to pay attention to microclimates in your garden. A microclimate is a small area where the temperature and moisture levels are different from the surrounding area. For example, a south-facing wall may be warmer than the rest of the garden. By planting heat-loving plants in this area, you can extend your growing season and increase your yield.

How to Find Your Planting Zone?

The USDA has created an interactive map that allows you to find your planting zone. To use the map, simply enter your zip code or city and state, and the map will show you your planting zone. You can also find your planting zone by looking at the USDA Hardiness Zone Map, which is available online or at your local nursery or garden center.

Conclusion

Knowing your planting zone is important for successful gardening in Wisconsin. By choosing plants that are suited for your planting zone, you can ensure that your garden is healthy and productive. It is also important to pay attention to microclimates in your garden and plant accordingly. Use the USDA Hardiness Zone Map or the interactive map to find your planting zone, and start planning your garden today!
