Frost Dates & Growing Zones

Understanding Frost Dates & Growing Zones

USDA hardiness zones describe how cold winters get, but frost dates are more important for vegetable gardening.

What You Need to Know

  • USDA zones help with perennial plants

  • Frost dates determine when to plant vegetables

  • Your local climate matters more than zone alone

Find Your Frost Dates

We recommend using a ZIP-code based frost date tool to find:

  • Your average last spring frost date

  • Your average first fall frost date

Once you know these dates, you can use our planting guides to confidently plan your garden.
