Understanding USDA Hardiness Zones
What Are Hardiness Zones?
USDA Plant Hardiness Zones are geographic regions based on the average annual minimum winter temperature. They help gardeners determine which plants are most likely to thrive in their location.
How to Use Zone Information
When selecting plants, choose varieties rated for your zone or colder. This ensures they can survive your area's winter temperatures and return each year if they're perennials.
Zone Accuracy
Our ZIP code lookup provides precise zone information based on your specific location. The current USDA map uses temperature data from 1991-2020 for the most accurate guidance.
Beyond Temperature
While hardiness zones are crucial, also consider factors like humidity, rainfall, wind, and heat tolerance when planning your garden for the best results.
