USDA Plant Hardiness Zones for Wisconsin

USDA plant hardiness zones are used to select perennials, landscape plantings and fruit trees that will survive over winter in your location. Check the color of the section in your area on the state of Wisconsin map. USDA Hardiness Zones and Average Annual Minimum Temperatures are also included on this site.

Soil Sample Testing Available

Fertile soils are the foundation for a healthy lawn and productive garden. Getting your soil analyzed to know what you have to work with is often the first bit of advice given to anyone starting a new lawn or garden or trying to rejuvenate an existing one. Testing soil about once every three is usually adequate. Getting the soil analyzed is one thing, but interpreting the numbers and understanding the basis for recommendations based on those numbers is another.
