To find out your garden's hardiness zone, there are a few helpful resources you should use:

1. USDA Plant Hardiness Zone Map:

   • This map is created by the U.S. Department of Agriculture.
   • It splits the country into 13 zones based on how cold it gets in winter.
   • Each zone has two parts, called ‘a’ and ‘b’. For example, 7a and 7b are different by 5°F.

2. Local Extension Services:

   • Many states have services that help with local gardening info.
   • They can give you specific maps and details about your area that affect plant growth.
   • It’s a good idea to check with your state’s service.

3. Online Tools:

   • Websites like the Arbor Day Foundation and other gardening sites let you enter your zip code.
   • This will help you quickly find out your hardiness zone.

4. Gardening Books and Guides:

   • Local libraries and bookstores have many guides about gardening.
   • These books often include information on which plants grow well in your area.

By using these resources, you can pick plants that will thrive in your garden's climate!
