Understanding Plant 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 Map Updates
The USDA updates the hardiness zone map periodically to reflect climate changes. The current map is based on temperature data from 1991-2020, providing the most accurate growing 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.
Need Your Exact Zone Information?
While the map shows general zone boundaries, ZIP code lookup provides the most precise zone information for your specific location.
