What Planting Zone Am I In?

Ready to transform your yard into a green paradise but feeling overwhelmed when selecting plants? Understanding your planting zone is essential to home gardening success. Let's learn the USDA Hardiness Zones and discover which plants will likely flourish where you live.

USDA Plant Hardiness Zones: What Are They?

Imagine the United States as a giant patchwork quilt, each square representing a different climate zone. Thirteen zones range from Alaska to Puerto Rico, representing a 10°F difference in the average annual minimum temperature. You can reference the official growing zone maps on the USDA website anytime.

Half zones exist along with the thirteen different zones, ranging from coldest (zone 1) to warmest (zone 13). The zone is divided into "a" and "b," representing a five-degree difference within each area.

The USDA updates the Plant Hardiness Zone map approximately every ten years, taking into account changes to the climate. The most recent update was in 2023.
